Astigmatism is a refraction of the eye is not normal conditions, related to the curvature of the cornea. The human eye is not perfect, if the cornea more curved in a certain angle in radians, while others relatively flat angle, the light will not be accurately focused on the retina, in which case it is called astigmatism.
Ordinary glasses can correct rule astigmatism:
Ordinary glasses can correct rule astigmatism, irregular astigmatism can not use it to correct, and the best way is the use of rigid contact lenses to correct, to good effect. Ordinary lens correction rule astigmatism effect is not the same, the greater the degree of astigmatism worse the effect of mild to moderate astigmatism can generally be corrected to normal, and a high degree of astigmatism correction is more difficult to good effect.
The astigmatic not is corrected will develop into moderate myopically:
High hypertrophy, astigmatism, far and near vision can not see the objects dependent regulation if not corrected as soon as possible, the development of visual function in early childhood will be some inhibition, grew up with Fake Oakleys glasses before until corrected visual acuity worse tend to form moderate myopically. Highly myopic astigmatism, although the look is far from clear, but near vision is also better visual function may also get some exercise is not completely suppressed, corrected visual acuity is generally better than the highly hypertrophy astigmatism. Whatever high astigmatism, corrected the sooner the better. Because the error corrected early, not only to promote the development of visual function, and deformation of objects and spatial orientation reaction to a small degree, the patient can withstand.
Astigmatism prescription glasses according to the following principles to give:
General hyperopic astigmatism less than +0.5 D, 90-degree axial myopia and astigmatism less than-0.5D axial at 180 degrees (the cornea by the oppression of the upper and lower eyelids, the degree of curvature of the cornea to the vertical direction than the horizontal radial the vertical radial refractive power, horizontal weak refraction) generally do not affect vision, can not correction; visual fatigue or affect vision, astigmatism should be corrected to the mirror.
Premise eliminate symptoms or do not affect vision, astigmatism should be low corrosively particularly high degree of astigmatism, astigmatic axis tilt in the direction, should be low corrosively, found that the shape of the object or to see things due to the full correction patients changes and the size of this case, hypertrophy astigmatism change than myopic astigmatism.
Within 3.00D axis myopic astigmatism, adolescents and isotropic should be given to correct. The individual oblique axis with different axis based on the ability to adapt appropriate by many more. Than 3.00D axis hypertrophy astigmatism, Fake Oakley Sunglasses, juveniles and isotropic who should be appropriately reduced by 0.50 ~ 1.00D; the individual oblique axis or hard-axis recipients, should be cut some, wearing glasses after 3 to 6 months in increase should be cut more hypertrophy astigmatism. Oblique axis, different axis degrees on the high, although the degree of reduction trials of patients, the symptoms are mild, but the prescription should be talking to customers to understand the phenomenon of deformation of objects and spatial error will undergo wear, wearing some time 'all adapt.
Under normal circumstances, if the spherical 1.00 ~ 3.00D, astigmatism 0.25 ~ 0.50D; spherical 3.25 ~ 6.00D, astigmatism 0.50D; spherical 6.25 to 8.00D, astigmatism 0.75D; ball 10.00D more astigmatism 1.00D column-plus vision to promote small and ignore the fatigue, you can not mirror column; appropriate given a certain degree of the cylinder, where the column more than value. Some patients with poor sensitivity can be difficult to distinguish Axial given close to the axial shaft. In summary astigmatism of the mirror: mild astigmatism, asymptomatic without astigmatism, have symptoms should wear full correction of astigmatism increase; highly astigmatism, wearing glasses for the first time to be appropriate, to reduce the glasses, to be then used to completely corrected; 2.00D following a simple astigmatism can be fully corrected, 2.00D more simple astigmatism can be divided into secondary correction; complex astigmatism where spherical in 3.00D cylinder 0.50D or less spherical in 6.00 above D, astigmatism 0.75D or more, or spherical in more than 10.00D cylinder 1.00D, where vision enhance required plus astigmatism correction.
If a patient is first wearing Replica Oakley Sunglasses, and high degree of astigmatism, if not meet, according to the ball column equivalents rules to reduce astigmatism, the so-called ball column equivalents rules: add 1/4 of the original column diapers spherical As a new spherical, 1/2 of the original column diapers constant as the axial direction of the rod lens. Example:-1.00DS to-6.00DC of * 90d, patients wear discomfort, the ball column equivalent of rules can be used to do the following changes:-2.50DS to-3.00DC * 90d.
How to choose glasses?
How to choose glasses optometry it? Glasses purchase of appropriate or not directly affect the comfort of the eye, or there will be adverse reactions. Some so-so to elect a cheap, or savings point of view, the use of someone else's glasses frame; some people talk about fashion the frames bigger and more beautiful. These cases are caused by glasses often not comfortable.
Wear Replica Oakley Sunglasses can make people look educated and gentlemanly, selection of glasses should not only pay attention to the style of the beautiful, but also can not forget the glasses with correction of refractive errors and the role of health care, we must put quality first. The glasses also the refractive media, to wear to the eyes, to have a beneficial effect on the refractive system must be eye, only to meet the refractive state of the eye glasses eye to beneficial.
Also, pay attention to the quality of the glasses. First diaper error must be within the standard range, generally no more than plus or minus 0.1D; second, binocular lens optical center distance and pupil distance consistent, not one high and one low; addition optometry measuring instruments must be detected qualified, the density of the lens to be uniform. The failure of the glasses do not use, even if the exchange is being used. In short, the correct selection of glasses should be co-ordinate from all aspects of optical lenses, aesthetics and mechanics consideration. Frames should pay attention to the mirror beam frames and nose, temples and ears-anatomizes, the weight of the glasses evenly distributed in the nose and ear, not too tight and not too loose, not to a high a low, so that the frame is fixed and held in the correct position, so that wear only comfort.
How to give the child chosen frames?
Many children in the optometry process can not be a good match, doctors have to spend a lot of effort in order to complete the of optometry checks and frame measurements, sometimes doctors can only observe the child's nose characterized to determine whether the temporal distance is not proportional to the IPD. This is to encourage children to choose their own favorite color, to seek the views of the child as much as possible, and then according to the measure of the bridge of the nose, the papillary distance discusses with parents glasses. The frames must pick the right. IPD is too small; the effect is opposite to the above case. Two lens optical center is not a horizontal line will be generated when the bottom upward, downward prism effect. Especially young children, can not speak, parents often mistaken for naughty children loved glasses. Sustained so bad to wear eye position, and so must be taken seriously, can not make the child emotional aversion to wearing glasses. Pediatric patients, aged only 2 - 5 years old, but also not very sensible to offer more encouragement. School-age children, 6-8 years old, they understand the importance of wearing glasses, will be a very good fit. Children's spectacle frames need to select the frame nose pads should be low, because the development of children's nasal yet full, not with adults. Rapid changes due to the growth process, using the annual pounds milliseconds characteristics to be hanging ears, it's the end of the buckle like a vertical direction, penetrates through the end of the elastic band, and then around the button in the young children on the back of the head. The tied straps should not be too loose, side Fake Oakley Sunglasses from a child's head slid down.
School-age children in the style and color of the glasses frame more children choose eyeglass frames also attach great importance to their pursuit of beauty as much as adults. Glasses for children, however, must proceed from reality, the majority of children are naughty fun, the lens shattered eye injury things often occur. Therefore, the best choice of lenses resins piece frame plastic frame affixed to the face and nose fit. Not suitable for children wearing metal frame, metal frame nose pads easily cause allergies and nasal pressure. Metal frame nose pads adjust inaccurate, nasal pressure phenomenon is even more serious.
Crystal glasses can keep eyes?
Crystal glasses can support the purpose of saying ancient spread so far. Ancient science developed, there is no better than the crystal material produced glasses, and the price is very expensive, only nobles to wear. So that it is very expensive and it is amazing, wearing the effectiveness of rising purposes. So far, a lot of people have not changed this ancient view. In fact, this is more than understand the crystal structure; crystal glasses do not know can not keep the purpose of truth. Crystal is a natural ore, uneven density, texture very different, limited production, and firm in texture, processing difficult and time-consuming and labor. Brown crystal with color, reducing the ultraviolet ray transmittance, but can not absorb infrared. Crystal stone often wispy streaks with tiny bubbles gather, into translucent (commonly known as the cotton fields), impede vision. This shows Fake Oakleys glasses and not raising projects.
You are not done cyclopedia refraction glasses? Not select the best lens? Bad eyesight is not your eye specialist to do an inspection? Is not used with contact lenses? These questions may seem simple, but not every personally attach great importance to wear eye easily broke into misunderstanding.
Misunderstanding one: "Some people say that young students become myopic, wearing glasses, will make deeper degree."
In fact, this argument is no scientific basis. We know that the incidence of myopia development is the result of genetic and environmental factors; most students myopia environment determinants. Young people are in the process of eye development, due to prolonged close reading, overuse of spasm and the role of the extra ocular muscles in the wall of the eye, so that the axial length, as well as poor posture, the partial eclipse picky eaters habits lead to myopia gradually deepened. Not because of wearing glasses after myopia. Contrary, wearing the right glasses, because the eyes adjust to relax, relieve eye fatigue, plus attention to eye health and correct bad habits, will be able to delay and control the development of myopia.
This is not a reason; first of all we have to clarify the purpose of wearing glasses to improve vision, vision correction. If you do not wear glasses, long time to learn, it is easy to cause eye fatigue. The long-term effect, the young students can not concentrate poor academic performance; further deepen myopia. If you wear the right pair of glasses, it is completely different. Buy frames professional consultant level sales staff will provide you with personalized service and products recommended for your facial features, can also be reached to make up for deficiencies, increase the aesthetic effect.
Misunderstanding number three wear glasses inconvenient not accustomed.
Moderate (300 degrees) above myopia or myopic astigmatism patients, not for a while to wear, for a while not wearing, that could create myopia. Young people less than 300 degrees, homework, reading do not wear, but pay attention to maintaining a distance of 33 cm and upright posture, or to look too far for good should always wear. Wear Replica Oakley Sunglasses also accustomed to the process used to always feel after a few days to adapt to the initial wear, of course, this process should not be more than two weeks, otherwise it should be checked diaper, IPD correct. Wearing, do not wear, is not easy to cultivate wearing glasses habits, often wear off his glasses, the glasses are easily damaged, deformed, but also deepen myopia.
Misunderstanding of the four it was convenience, casual use of borrowed glasses.
This practice is wrong. If you borrow casually borrow other people's glasses definitely add to the eye adjustment burden to promote the further development of myopia. Even if the refractive the consistent nor borrow each other, because of the distance of each IPD two lenses optical center inconsistent, both center distance can not completely overlap, wear likewise inappropriate Over time, the eyes will feel fatigue, reaching less than the purpose of correction of myopia.
Regular eye glasses even after review, young people are generally inspected once every three months, vision loss, should be equipped with the appropriate degree of glasses, wearing a low degree of glasses; the same can not be corrected visual acuity, unable to alleviate the burden on the eyes the degree will deepen. In addition, young people in the growth stage, his IPD is also growing, so eyesight checked regularly, periodic re-optometry, not only to adjust the diaper number, but also to update the IPD.
Misunderstanding six: wear glasses do not have to review the
In myopia in children with glasses, many parents are no longer with their go to the hospital for check-ups. This practice is wrong. Clinical practice, often so myopic children wearing glasses to go to the hospital to have the following benefits: 1, can clear whether the children's original pseudo myopia has been cured; 2, can clear the false mixed myopia in children myopia has been cured; 3, can clear the children's original true myopia development.
Therefore, parents are myopic children wearing glasses, often with its go to the hospital to review, at least annually review once, so as to keep abreast of changes in condition of myopia in children. For school-age children do not suffer from myopia, parents should always take their eyes go to the hospital to check. If school-age children with normal vision do not adhere to the scientific eye, its vision is also likely to decline.
Seven Mistakes "beautiful eyes in order child can give their children wear invisible Fake Oakley Sunglasses Once the children wear glasses, the child's eye will affect the appearance of the eyes of a child, so some parents think that children wearing contact lenses
Talk about their point of view in the Director in the issue of contact lens wear, he said: It is a commonplace problem, he suggested, considering their children choose to wear contact lenses, special needs. Students do not need to choose to wear contact lenses because of the safety of the lenses require a relatively high use, some use unscientific methods will bring serious damage to the cornea. Age small children, in particular, are not allowed to wear contact lenses, not very good due to the conservation of domestic wear contact lenses because severe dermatitis cases are common.
Misunderstanding 8: Child lingers pupil can glasses
One to leave, busy parents, many parents seize the time to arrange a variety of classes for children, but child vision bad glasses need to go to the hospital dilated eye exam, due to the scattered pupil child can not participate in kinds of classes, and some parents have given a free hand for the children to choose a the computer optometry distribution Fake Oakleys mirror.
Domestic and international studies have shown that more than 90% of keratin can significantly benefit from contact lens optical correction and treatment, this technology can quickly and effectively improve vision and restore the functions of binocular vision, and effectively control the development of lesions and adolescent patients recovery normal learning, life and work. Clinical investigation keratin morphological changes in the characteristics and the extent of visual impairment, will explore how organic the choice of using a variety of different materials, different designs, different combinations of contact Replica Oakley Sunglasses.
Bio-microscopy, visual acuity and ocular refraction, corneal topography examination of computer-aided A super and corneal thickness, ocular surface tear film examination and corneal endothermic cells in check, will be the keratin divided into suspicious, mild, degrees, severe and acute edema of five clinical suspicion and mild keratin usually spherical and non-spherical design permeability rigid contact lens (RGPCL), three-point contact fit under the principle of small diameter can state of partial steep and large diameter gentle status, analyze its own advantages and disadvantages, according to the actual needs of choice. Can be applied to the soft contact lens (SCL), and may be non-spherical design, the tonic design or special design. Individual cases to trial Sotho-K lenses (Ortho-K CL), but must be treated very carefully.
Moderate and severe keratin preferred is also RGPCL the 3-point contact and point contact principle of fit, such as vision correction satisfied patients can accept ordinary spherical lens and spherical lens can be. The prominent corneal overall deformation obvious, ordinary RGPCL can not be stable at the surface of the cornea, poor fit state, foreign body sensation, pain and other symptoms, the corneal surface injury-prone, consider selecting a specially designed type RGPCL, such as the rear surface of 3 arc or 4 arc spherical and non-spherical design (Comfort cone, Mufti-Curve CL Ⅰ, Ⅱ, Ⅲ), the rear surface of the cone-shaped design (Rose K, M curve Ⅰ, Ⅱ), eccentric design. Also consider using piggyback ask is a CL (SCL + various RGPCL, hard and soft mirror combination system), used properly will significantly improve the examination of paired power to improve the state of the fit, relieve symptoms and prolong the time wearing glasses. But long-term use concerns corneal chronic hypoxia response. Acute the edema period of keratin may utilize the SCL or Piggyback CL alternative compression bandages with drug therapeutic effect and orthopedic effect the general the edema basic subsided after 2 weeks to 6 weeks, the lesion flattens, scarring, if not completely block the optical center, can continue to take advantage of the RGPCL or Fake Oakley Sunglasses.
CL improves eyesight. During treatment should pay attention to the frequent observation of a variety of changes in the cornea after penetrating Elastoplasts graft and prevention purposes to restore transparent but still low vision patients needed further optical correction, based on experience most still in corneal topography under the supervision to rely RGPCL good vision correction. Wearing glasses and wearing glasses should be closely observed corneal health status, changes in corneal endothermic cell density and morphology, cell density is less than 1000/mm2 in particular should pay special attention and close observation of the presence or absence of the primary disease recurrence and immune rejection, strict control infection. How to choose a variety of contact lens fitting lens materials, design, base arc, peripheral arc, diameter, refractive variable parameters, how to observe the state is in the evaluation of CL and corneal appropriate fit, based on symptoms, signs, with appropriate state, lens changes, adjustments and fine correction, specific analysis and discussion will be based on specific cases. Orthodontic treatment for keratin, both strict cautions must be patient and meticulous, is a long-term medical services hard work. Patient compliance requirements, and to emphasize the periodic review, the timely replacement of lenses, conventional self-test, the importance of careful care and cleaning lenses. Both doctors and patients closely cooperate to ensure to maximize the power of the contact Fake Oakleys mirror.
1, high myopia above (-6.00ds)
Completely corrected initial glasses, such as significant adverse reactions, you can start by 2/3 of the diaper with Fake Oakley Sunglasses With the reduction of the adverse reactions gradually achieve satisfactory correction after 3 months. Sometimes incremental degrees to fully correct up to 3 times, each time raising the general-3.00D or less, this is because the culinary muscle to restore normal regulation requires a process of adaptation. Had worn high myopia patients, it is also likely to increase once the diaper can achieve satisfactory vision correction.
In fact, the elderly long as they can meet the needs of daily life, the degree glasses may be appropriate to lower both so far but also nearly with. For example, 60-year-old customer-12.00ds real with-9.00ds, such as distance vision corrected to 0.8 near normal, no adverse reactions. As for the Pd take far, the near Pd of the average, only choose the far or near to take corresponding Pd. For Students should strive to be completely corrected. Take the hole mirror on corrective lenses when is difficult to judge whether the vision correction can further increase if the vision does not improve, the judge corrected visual acuity stop here. To do so, will help speed up the appropriate choice of diaper lens.
2, high hypertrophy (+5.00 ads)
Phonic: unusually active due to the adjustment of children eye is still required in the preliminary optometry dilated or cloud method to ease the adjustment to be pupil returned to normal (with compound tropic amide in the first two days, with atropine After one week, three weeks after atropine) and then line optometry, and then comparing the before and after dilation diaper prescription. The general prescription on refractive located between before and after dilation refraction, because it is necessary to exclude regulating intense interference, but also consider the daily objective existence of the remaining adjustment. The dominant hypertrophy degree +1 / 4 recessive hypertrophy degree as the degree glasses, or take 2/3, the day after dilation diaper, but are not as good as the former method is accurate and reliable. Cloud method to ease the adjustment, can be determined on the day the prescription, but not as good as the dilated effect. As ever with Replica Oakley Sunglasses can be suited to a marginal decrease in the degree mirror, mirror degrees to gradually increase in the short term fully corrected to prevent isotropic and myopically occurs. For youth and adults, due to adjust gradually reduce, without cyclopedia refraction, the cloud method when necessary, take the highest degree of normal vision or better vision.
Aphasia: common in the cataract lens extraction in patients with general admission +10.00 ads (+11.00 ads) plus half of the original diaper glasses degrees. For example, a patient in the lens removed before the myopia-2.00ds can try to take; original +2.00 ads, try to take or.
3, anisotropic significantly
Carleton and Mandy anisotropic due to the size of the image on the retina to produce 5% of the difference between the maximum limit for two melt like. Usually advocate the use of an ordinary lens correction of anisotropic, Fake Oakleys on both sides of the lens degree difference can not exceed 2.00d, which has become a routine can do of course, very good. Found 100 cases of anisotropic patients, two diaper difference 4.00d often full correction video more than 3%; diaper difference 4.00 ~ 5.00d, most can be corrected video usually difficult to correct in the 3 to 4%; diaper difference in 5 ~ 6d, the critical value is accepted and not accepted, should strive the full corrected video than 4 to 5%, diaper difference in more than 6d , and more than the loss of stereo sis, the mulch video more than 5%, should be an appropriate part of the correction. The author has provided patients with two glasses diaper difference 6.00d above, there is no adverse reaction. Example 1, the 42-year-old male patient, uncorrected visual acuity right 0.1, left 0.25 glasses right-13.00ds-2.00dc → 0.4, the left-2.5ds-0.5dc → 1.0; Example 2, a 30-year-old male The right of patients, uncorrected visual acuity of 2.0, left 0.1 glasses right Pinging, left +9.00 the ads +2.00 dc × 163 → 0.8. The cases two diaper difference in 10d above, but it feels good, and can prevent the deterioration of the waste with myopically tendency. Seen great individual differences in the ability to adapt to the spectacle-corrected, especially age-related, it may be because the main eye play the sake of visual function advantages.
Dazzling variety of skin protection sunscreen, sunscreen, sunscreen gloves, hats, and umbrellas ...... summer could fill volumes. In most people's understanding, the tan is for the sole purpose of the summer sun. However, the burning sun, especially in the strong light of noon, the damage to the eyes can not be ignored, so, prepare a Replica Oakley Sunglasses; sunscreen is essential to doing for their own eyes.
Sunglasses, also known as sun mirror, prevent sunlight intense stimulation, protective equipment used to protect eyesight; use can be divided into three categories: sunshade mirror, light-colored sunglasses and special purpose sunglasses. Among them, the sun mirror is used for shading, light intensity more than the human eye adjust ability, you can play a protective effect on the human eye; light-colored sunglasses, the blocking effect of sunlight than shade mirror, but its rich colors, suitable for use with all types of clothing, with a decorative role; special purpose sunglasses block the sun, is commonly used in place at beaches, ski resorts and other strong sunlight, UV resistance and other indicators have higher requirements.
With the aesthetic taste of the development, the decorative role in the light-colored sunglasses gradually enlarged to become a factor of sunglasses top priority, especially in the summer, in addition to a variety of hot pants, tidal skirt, shoes outside the United States, the sunglasses seize certain dress "Oxide.
Reporters interviewed found the increasingly strong market this year, the requirements of the sunglasses this decorative function, only the compact design, unique sunglasses to take a slice of the market, and the sunglasses trend just as much as changing clothing and jewelry.
Before in Xian in a sunglasses shop, rows of colorful Fake Oakleys sunglasses is placed on top of the frame, in addition to the traditional black, brown, red, pink, green, blue, and green with blue color. Not only that, some gradient lenses also appeared in the market, people produce the feeling of an intersection with your eyes through the lens.
Lens color and full of tricks, many manufacturers have begun in the frame to start the article, Chen child Airlines, Inhuman Department Store, a sunglasses store boss told reporters that the recent trend of sunglasses is the gradual relaxation of the thickening of the border and mirror legs. The reporter also noted that store sunglasses, round box or the box, there are more and more generous, more and more exaggerated the potential large scale several border width, even Neighed to block the small side face.
Novelty style can attract the attention of countless young people, but some of the classic traditional styling allows 60, 70, 80 after their collective nostalgia a lot of big sunglasses manufacturers have joined this "tribute retro "ranks. Round frame rounded from the 1950s to the 1980s, the Founder of the square frame, a wide range of products, interpretation of the entire course of development of the sunglasses.
Sunglasses sold online product people overwhelmed everything ordinary products from tens of dollars to a thousand dollars of luxury brands, not only the shape of Variety and texture also spared the article. "Usually the jewelry field use of the material, in addition to the traditional precious metal available for designers free play space is not large, sun glasses can be regarded as an exception, a high-tech titanium alloy and carbon fiber material can be used, and different color stitching, the combination of different materials, in addition to stability and superior performance, but also can show a stylish texture can not be copied.”
In addition to its own function and style on the corporate ladder, Fake Oakley Sunglasses often in combination with other jewelry appearance, a combination of a visor with sunglasses on the market, not only to give face to bring a comprehensive sun protection, also lenses designed to wind-integrated structure, great sports atmosphere.
A lot of people in life, almost always and the glasses became involved. The experts remind therefore, currently optometry workers most basic to the most commonly used, but one of the important works. Patients with poor vision need glasses to formal institutions optometry must be noted that it may not know, in fact, the day different time, optometry; the result is not the same.
When optometry best results?
Day morning refraction effect is usually the best.
Optometrists and Fake Oakley Sunglasses the best selection in the morning, this is because the eye is far and near different objects, primarily depends on contraction and relaxation of the culinary muscle, lens thickness in stretch to adjust the focal length. Eyes enough rest after a night of culinary muscle available completely relaxed the most accurate results of optometry.
If the election in the afternoon or evening, the eyes after a day of use, especially in some children a holiday after a long time sitting in front of a computer screen playing games, culinary muscle in a state of fatigue, then glasses, optometry results may be too high. Wearing such glasses might not feel any discomfort, but two or three days, dizziness, dry eyes and other symptoms may occur.
Hindus examination before the glasses is very important
Decreased vision, see things, not simply a problem of myopia, is likely to be the funds went wrong, and who have this condition, should go to the Eye Hospital for treatment. With Replica Oakley Sunglasses passed before the eyes of the inspection can prevent accidents from happening, while screening out cyclopedia refraction.
Disable contact lenses before optometry
The computer optometry commonly used method, which uses the optical focus measured specific degree. But the mechanical read the data, and does not take into account the subjective feelings of the human eye, with glasses, do not rush to go with good glasses, try them for some time, was not to hurry to leave, if you feel unwell to re-optometry. Experienced optometrist will take full account of the status of the customer's eyes, give a reasonable prescription. Therefore, it is best to professional organizations with Fake Oakleys glasses.
In recent years, the increasing incidence of myopia, especially due to pay attention to eye health and lead to vision loss in the older and more pupils. Meanwhile, optical shops in the streets of the more open the more, and most of them offer free optometrist services, a lot of people directly into the optical shop glasses. But these glasses optometrist shop has qualified qualification refraction results are accurate? Indeed, there are many patients with myopia have encountered because of improper glasses cause dizziness, discomfort, decreased vision, increased the degree of myopia, etc.. Therefore, experts advise, optometry with Replica Oakley Sunglasses or professional institutions, formal the optometry scientific glasses is particularly important to the children of the true myopia.
Tell wear glasses myopia, science
If children see things often squint eyes, Robyn, frequent blinking, decreased vision, that affect academic performance, you should be checked in time, the difference is that true or false myopia. The pseudo myopia children dilated avoid eyestrain, to adjust habits with the eyes; the true myopia in children the need to go through the formal medical optometry wear glasses. The vision is still wearing glasses decline may be due to inappropriate glasses.
Formal glasses five program essential
1, do eye health checks, including slit lamp ophthalmologist, slit lamp examination can exclude dermatitis, trichina, cataract and other eye diseases, ophthalmologist glaucoma and other diseases can be excluded, these diseases can cause decreased vision; cyclopedia refraction and check. For the initial glasses adolescents, regardless of age must dilated time under the age of 12 should be more than a week, more than 12 years old can be short, mid-rise, continuous drops of atropine the migrate liquid 5 times, each time interval of 5 minutes. ; 3, visual inspection, look for lenses. Is often said that inserts optometry, and examine a variety of lenses to try them adapt; 4, do binocular vision adjustment check, can find out by checking the binocular objects collection, with the extent of spread, with the glasses can be more appropriate; 5, the above four-step prescription glasses, the only way with Fake Oakley Sunglasses it is more appropriate.
The advantage of medical optometry
Firstly, medical optometry can properly address the needs of the patient's refractive correction, in particular, is the ability to meet the functional status of the relevant visual adjustment, which is to ensure that the basis of refractive normal and healthy and normal visual.
Second, the children of refractive errors not only affect children's vision, and some can even lead to Arabic’s and myopically. Many children Arabic’s, myopically associated with refractive errors. So, we need to understand the refractive status, at the same time understand more visual features, to make appropriate and timely assessment and intervention
Third, the refractive error may be one of the manifestations of many diseases of the eye, such as corneal opacity, lens disease, glaucoma, and oracular disease and so can be expressed in the refractive error of the eye. For patients with refractive errors in these cases, the medical optometry timely help patients find these eye diseases, so that patients receive timely and appropriate treatment.
Medical optometry, we can understand the myopia by refractive state their vision, clear the nature and extent of the myopic eye diseases, and provide an important reference for the diagnosis and treatment of disease. The experts have warned that primary and middle school students also work hard to avoid overuse, do more outdoor sports, conduct regular professional Optometry detection checks, pay attention to nutritional balance, Fake Oakleys, fast food, eat more vegetables, fruits.
