1,100 degrees also with glasses: Some people believe that a relatively low degree of myopia or myopic just who are "pseudo-myopia", do not have with Ray Ban Outlet sunglasses. Some people worry that if they are pseudo-myopia, once the glasses it will become a true myopia.

Experts point out that as long as the dilation, refraction measured the degree of myopia, even if only 100 degrees, is the "true myopia", in relation to the timely glasses. For nearly as the degree of the people, with glasses to avoid further deterioration of vision and myopia will not be darker, but there is no pseudo myopia question therefore becomes true myopia.

2, a poor visual acuity should also wear glasses: Some people exist anisotropic problem is that we usually refer to poor eyesight, poor eyesight or even two eyes at 250 degrees. However, because these people tend to have a better eye sight, so do not want glasses. But the fact that poor eyesight health effects on vision equivalent to one wearing high heels, a person wearing flat shoes, is very negative, are also prone to visual fatigue and even other eye damage.

3, glasses may not be always wo: there are people with myopia after too infrequently wo for aesthetic, but conce that it would increase the myopia. However, experts reassured to these people, because of the time wearing glasses for myopia has not decided whether to deepen meaning. Generally speaking, if we look at things (such as watching something distant) feel relatively hard, can not see, they must wear glasses, if you can not see clearly when reading wear. The general principle is to the eyes to see clearly, do not feel tired prevail.

4, Presbyopia as soon as possible with Ray Ban Wayfarer Glasses: Some old friends after Presbyopia not seriously, I thought I could make do see things, no need reading glasses. However, Presbyopia and myopia also cause visual fatigue, resulting in Presbyopia coupled with reading glasses as soon as possible thereafter to avoid aggravating eyestrain. In fact, some people like reading glasses with old walking stick to prop as normal, not too troublesome, or afraid of being a joke.

5, the preferred daily disposable contact lenses, monthly disposable: the majority of patients with myopia has long been clear long-term wear contact lenses on the eye hazards, but often because of the pursuit of beauty and can not renounce the use of contact lenses. Experts pointed out that frequent replacement contact lenses, each deputy's use of time not exceeding 8-12 months, conditional, the preferred daily disposable or monthly disposable. Contact lenses and mirror frame alteately best wo daily wear contact lenses longer than 8 hours.

Experts also pointed out that a lot of people after extended wear contact lenses, wear glasses every time, you will feel dizzy, wearing contact lenses do not have this feeling, in fact this is the eye's own functional deterioration of the signal.

6, long-wearing "color film" the most evil eye: experts said, not only for healthy people of myopia beautiful and wear "color contact lenses" (commonly known as color film), which is not advocated, because there are many within the color film color, so that the light is not normally delivered to the eye, with a special lens structure, than ordinary contact lenses more harmful to the eyes. If it is short-sighted people, who do not choose a better degree of color film, would prefer Cheap Ray Ban Sunglasses, because there is degree of color film only to beautify the eyes have to bear vision correction features that make the thickness and color more complex and not advocate.

To choose a suitable pair of Ray Ban Outlet for the kids sunglasses, first eye examination, after excluding effects within and outside the vision of the eye disease, optometrist again.

The first step is for Mid-rise optometry check, different kids of different ages Mid-rise. Mid-rise purposes was paralysis of the culinary muscle of the eye, removed because of regulation force too strong causing false myopia in children, Mid-rise optometry true myopia degree of access to data. After Mid-rise optometry degree obtained, should choose a suitable pair of glasses for the kids.

Glasses should pay attention to the following several points:

The first, was also equipped with myopia, to beautiful does not often wo, but are worried that such an approach would increase the myopia. However experts give these people calm down, because myopia glasses wearing time deepening is not decisive. In General, if you look at something (such as more distant things) sense is hard enough, and they are not clear, you have to wear glasses, if read sees clearly can not wear. General principle is subject to eyes to see clear and not feel tired.

Second, Ray Ban Wayfarer Glasses with optometry degree must be of identical data on single.

Third, children face size and pupil distance, choosing the right frame.

IV, geometric pupil distance and distance from the center line of the eye lens, lens transparent texture, no cracks and spots.

V, glasses once, should face a 10-20 degree angle of around, both for objects in the distance, and conducive to reading.

The so-called optometry is through the main senses or he felt checking out eyes, exact number of diapers, with this as a basis to enjoy Cheap Ray Ban Sunglasses.

Optometry in two ways: one is a subjective refraction, refraction without large pupil, but depending on the patient conscious vision determines the number of diapers, most glasses company using this kind of method, which is characterized by relatively simple, fast, can be substantial. This law applies to persons over the age of 40, but for kids under 12 years old, hypertrophy, astigmatism, pseudo myopia project easy errors, should use a second method of optometry, Mid-rise optometry.

There are two types of regular and irregular astigmatism with Ray Ban Outlet Sunglasses method also differences. Irregular astigmatism can not be corrected with the optical lens, only rigid contact lenses to be effective. The rule astigmatism can be corrected with the optical lens to improve vision. As for improving the degree of visual acuity depends on the degree of astigmatism, the two inversely. Generally mild to moderate astigmatism corrected visual acuity is often up to the normal range, high astigmatism would be difficult to get a good visual acuity, especially in highly hypertrophy astigmatism, hypertrophy nearly clear view can not be dependent regulation was like.

As soon as possible in early childhood is not corrected, the development of visual function subject to certain suppression, such as older only wear corrective glasses, vision correction even worse, tend to moderate myopically. And highly myopic astigmatism is better, although as far unclear, but near vision or better, depending on the features to get some exercise, not completely inhibited, corrected visual acuity better than high hypertrophy, astigmatism, but it should be corrected as soon as possible. High astigmatism corrected early, not only to promote the development of visual function, and object deformation and spatial positioning errors reaction to be small, the patient can accept to a large extent, and easy to adapt.

Astigmatism glasses with the following principles:


(1) 3.00D less positive axis myopic astigmatism, children, adolescents and those can be corrected oblique; young adults who wear proper axial astigmatism glasses, appropriate to reduce the O ? 25D ~ 0.50D, individual axes are oblique axis varies according to its ability to adapt as appropriate by many; hypertrophy astigmatism addition to inteal oblique herein should be cut more. More than 3.00D axis hypertrophy astigmatism, children, adolescents and those oblique, appropriate reduction 0.50D ~ 1.00D, oblique axis of individual recipients or hard-axis, then cut some more, to be wearing three to six months to adapt and then give increased; hypertrophy astigmatism should be cut even more; oblique axis, different axis and degrees on the high, although the degree of reduction, the patient auditions, interference with mild symptoms, but in giving prescriptions should say clearly wearing Ray Ban Wayfarer Glasses will produce visual distortion and spatial errors and other phenomena, need some time to adapt to the patient to wear, in order to avoid conces about their world will not wear glasses aside. Some patients previously long-term wear glasses incorrect axial astigmatism, visual acuity improved, because of the error has been adapted glasses, new glasses properly corrected to produce new things like location and spatial error, again, to adapt, often it can not accept, and After wearing glasses need some time to adapt, especially in elderly patients is more prominent.

Generally spherical 1.00D ~ 3.00D, astigmatism 0.25D ~ O.50D who spherical 3.25D ~ 6.00D, astigmatism 0.50 persons, spherical 6.25D ~ 8.00D, 0.75D of astigmatism who 10.00D more spherical, astigmatism 1.00D persons, such as column-plus vision to promote small and ignore the fatigue does not give; those who go beyond the above range, discretionary grant; Some patients with poor sensitivity of the axial difficult to disce, when close to the correct axial give.

To reduce it in degrees, wearing habits completely corrected, the following simple astigmatism can be fully corrected 2.00D, 2.00D or more can reduce it two times corrected; complex astigmatism where less spherical in 3.00D, 0.50D cylinder in the following or ball Mirror in 6.00D or more, more than 0.75D of astigmatism in the mirror ball in 10.00D or more cylinder in 1.00D, who are required to improve vision correction.

(2) Where the physiological low astigmatism who hypertrophy astigmatism is less than +0 ? 5D, the axis 90. , A 0.5D less myopic astigmatism, the axis 180. (Due to the coea by the upper and lower eyelids pressure, vertical diameter greater than the horizontal curvature between the diameter, the so vertical diameter between Quiz Lining, horizontal diameter inflected weak) generally does not affect vision, and usually do not have to mirror. Such as astigmatism axis has changed, affecting vision or visual fatigue symptoms, although the degree of astigmatism is low, it should be corrected.

Either low or high astigmatism, do not use Cheap Ray Ban Sunglasses overreaction, axial must be correct, otherwise the patient will leave the new refractive errors, resulting in unacceptable interference with patient symptoms. Without affecting vision or eliminate symptoms circumstances, astigmatism correction should be low, especially in the higher degree of astigmatism and axial shaft between those who are not, the correction should have reservations, the full correction will make the patient feel things like the size and shape of non-original appearance varies to cause deformation of the spatial location of the error.

In the eye clinic or optical shop, often encounter bad eyesight, but still wearing Ray Ban Outlet Sunglasses can not correct the problem, sometimes even experienced optometrist feel embarrassed to clinical ophthalmology perspective, from the following aspects with fellow glasses industry discussed.

Optical shop of evidence stricter than that evidence of clothing stores, restaurants. We need to have industrial and commercial production under license, its operations lenses, frames to have production licenses and 'QS' signs, glasses optometry shop also must obtain a production license, optometry store the instrument must accept the identification of once a year, but many small optical shop unable to produce optometry instruments accreditation report.

Refractive errors are the main target of the optical industry services. And these three cases can not be satisfied through the spectacles corrected. In the short terms; eye because of high myopia, myopic eye is blinding eye disease. For high myopia and myopic eye is often associated with serious complications, so the deeper the degree of correction of the more dissatisfied.

Hypertrophy often accompanied by myopically. Should be four to six years, a critical period of visual development, vegetables pupil optometry, wearing sufficient degree of positive lenses, and then strengthen the eye trained to facilitate recovery and improve eyesight. And each one was to review the interchangeable lens. Otherwise, wait until the old later, then corrective glasses, with or without the formation of strabismus, vision can not be corrected. Hypertrophy started wearing glasses when not wearing glasses eyesight even worse, a doctor should be under the coordination of parents of children with hypertrophy do ideological work, insist on wearing glasses and training. Visual acuity in the myopically eye, still can not immediately remove the glasses. Only visual spectacles and not wearing glasses in the case are the same, but when not wearing glasses and no eye fatigue, can take off Ray Ban Wayfarer Glasses.

Eyes only rule astigmatism correction to wearing glasses. Astigmatism is too large or two irregular astigmatism or irregular astigmatism, wearing Ray Ban Wayfarer Polarized glasses is not satisfied with the correction.

Anisotropic; press two Jane anisotropic 0.25D, two images on the retina can occur in 0.5% of the size of the difference. Two retinal aberrations can not exceed 5%, or can not tolerate. If two or more diapers difference in-3.5D in vision correction, you may want to give up a vision correction, take a lower refractive vision correction eye gaze as life. This can only be monocular gaze.

First, young people suffering from nearsightedness, farsightedness and astigmatism with Ray Ban Outlet sunglasses have to go to the hospital to check visual acuity, cyclopedia refraction, and measure the distance between the two pupils. Cyclopedia refraction is to eliminate the impact of regulation and its components caused by the pseudo-myopia, and application of drugs to the eye's culinary muscle is completely paralyzed, in the case of mid-rise optometry carried out.

Measuring the distance between the two pupils is to determine both sides of the glasses lens optical center distance between the two must be consistent, otherwise prism effect may occur, the interference of visual function after wearing glasses dizzy, depending on the distortion, eye soreness, fatigue and so on.

Second, choose glasses frames to fully meet the requirements of optical lenses and frames inclination and so on. Big eyes to choose a large frame, eyes small selection of some of the smaller frame, fat round face suitable for wearing thick frame, lanky frame for round face, flat round face should choose a slightly narrower bottom square frame. Not suitable for children to wear metal frame, because the metal frame nose pads can lead to allergies and nasal pressure.

Third, the lenses should be based on age, occupation, frequently engage in activities by wearing Ray Ban Wayfarer Glasses preferences and other factors to choose from. Glass lenses, high hardness, not prone to scratches, but is easy to shatter. Due to the nature of work or other reasons make glasses easily stained with dust, causing the lenses to scratch, the best selection of glass lenses. Resin lenses, light weight, not easy to be broke, but lower hardness, prone to scratches. Because most children naughty fun, eye injury lenses broken things often happen, so it is best to choose child resin film. If you are not satisfied with the lens thickness or appearance, you can choose thin lenses or spherical lenses. If you regularly engage in outdoor activities or travel, photo chronic lens is a good choice.

Fourth, frame lenses currently on the market many varieties, prices vary greatly. Many parents in the selection of lenses for their children, the blind pursuit of expensive, that only your glasses is the best, most expensive glasses is suitable for the child's eye development.

Students to choose the most important prerequisite for glasses to fit you do not blindly pursue fashion pick rimless frames or punch. Children under the age of 10 can choose glasses nose pads protect the soft side of the glasses shelf, over the age of 10 can basically choose full rim frame.

Children choose lenses should first consider the hardened resin spectacle lenses, glass lenses fragile, easy on eye damage in children. Resin lens astigmatism axial main requirements precisely, the distribution of the luminosity must be accurate, can not have a scratch on the lens, can not have bubbles and impurities, the degree of preparation of the child glasses must meet the standards promulgated by the State Quality Inspection. Refractive error should be awarded in the country within the scope of the requirements of the standard.

Finally, you must understand the precise grinding spectacle lenses and accurate optometry equally important must be in strict accordance with the grinding of glasses opened by doctor’s prescription glasses. So with Cheap Ray Ban Sunglasses to a regular hospital centers or specialized glasses company, and not just in the street vendors to purchase, or take someone Else's mess wearing glasses.

Usually parents give their children with Ray Ban Outlet sunglasses, mostly on the careful selection of frames, lenses only for a simple look. In fact, the intrinsic quality of the lens is critical.

In recent days, with winter approaching, the various glasses shop packed with schoolchildren.

In optometry outdoors, many small patients, accompanied by parents holding their own optometry report walking to see, some parents report seeing optometry, surprised and said: "how degrees and long?" According to doctors, with the opening of the approaching, students these days to check particularly, is about 70% of the number of visits. Most of these small patients before school only to find the original spectacles was not enough, had to come to the hospital to re-optometry.

In the "old" way outside Henry optical shop, many parents are children change lenses. Experience with his son just finished a light lady told reporters: "The children have been myopic eye is not severe, last semester in a small optical shop with spectacles. Then simply pick the frame appearance, ignoring the quality of the lens, the result wearing head confused. This back Henry an experience than the actual vision lenses nearly 200 degrees. Kendra you say more! "

Usually parents give their children with Cheap Ray Ban Sunglasses; the most carefully selected on the frame, the lens is only a simple glance. In fact, the intrinsic quality of the lens is critical. Right now some individuals to compete for customers shop have played "gift glasses lens" ads, some with bubbles, spirals, stripes, ghosting lenses donated customers. Such inferior lens wear, it will cause eye astringent and visual fatigue. Remind parents: a child with eyes must pay attention to the quality of the lens, do not be cheap.

With good glasses should also pay attention to what?

Glasses, the lens optical center should also note that the IPD (i.e., the distance between the two pupils) must be consistent. Glasses generally associated with frontal inclination of 10 to 15 degrees, the mirror - from the right eye (usually 12 mm). IPD is very important; a low degree of error of the lens IPD should generally be less than 3 mm. if you have dizziness, do not apply for the first time, require the review of glasses prescription and lens quality, including degrees, interplanetary distance and the optical center of the lens. If temporarily does not adapt, adapt.

After wearing Ray Ban Wayfarer Glasses still pay attention to vision care, regular review, especially young people, at least six months review time.

First distinguish between true, false myopia if you suspect child should go to a professional Ray Ban Outlet Sunglasses Eye hospital, through dilated, distinguish true, pseudo myopia. Pseudo myopia is often incorrectly used as eyes; the eyes are not resting, watching the distant things clear. If you pay attention to eye health, there is hope to restore normal vision. But if not promptly corrected pseudo myopia and treatment, a long time will develop into a true myopia.

After wearing glasses to correct myopia has been confirmed as true, in relation with a right glasses to be corrected, and often, rightly wear. Wearing glasses is not only to improve vision, but also to make the regulatory function of the eye back to normal state, to avoid eyestrain degree increases.

Not suitable for direct use as computer optometry prescription computer optometry result there will be some error, not directly as a prescription. Professional eye hospital medical optometry method using formal, first by the doctor in the eye, eliminate eye disease, and then after Mid-rise, of computer optometry and checking steps, such as shadow, balanced binocular vision glasses.

Does a child need to wear Cheap Ray Ban Sunglasses, depending on whether the child is true myopia? If it is false myopia can not wear because pseudo myopia is functional, caused by a spasm, axial normal. More common in younger age of onset time is shorter, lower diaper Children. Pseudo myopia by rest and proper treatment can be restored to normal.
Once diagnosed as true myopia, and less than 1.0 will need binocular vision glasses. If not promptly glasses, his eyes not see the status of a long period, it will lead to vision deteriorates rapidly. Children and adolescents is a progressive myopia, wearing myopia does not make myopic reduce or stop, it will not speed up the progression of myopia.

In addition, the glasses, the read and write, watch TV, or even visit, shopping, etc. all use of occasions to wear eye glasses, pay attention to eye health and vision regularly to the hospital.

For many parents in order to improve the situation of the blind child vision eye doctors believe that some of the equipment and drugs phenomenon, Sun Zhou specifically pointed out that so far, the world's medical community is still not found a long-term perspective is indeed effective drugs and devices. So the children suffering from myopia, the best way is to immediately wear glasses.

Properly wear Ray Ban Wayfarer Glasses, degree not more wear deeper degree of myopia development or not, and has no direct relationship with glasses. Myopia wear the right glasses, pay attention to eye health, myopia will stabilize at a certain level. But if it is not suitable for glasses, will increase the burden on the eyes, but decreased vision.

Adolescents with glasses are a very important thing, if fitting properly, will cause strabismus, astigmatism, and the degree to deepen and other adverse consequences.

One, to choose the right glasses

The intrinsic quality of the lens is critical; we must meet the national standard glasses. Elect Ray Ban Outlet sunglasses is best to choose high-definition films, transparency bright, if more than +4.0 D should be considered when matching thin film. Because it is the outdoor temperature change with the sun color deepened, affecting reading room, working. Currently the most popular is a resin film, because the resin sheet is light, unbreakable, and very suitable for young people like sports wear. Of course, be sure to choose the selection of films, high hardness, transparency, light, does not exist Hugo Gang, bubbles, spirals, stripes, ghosting and other defects, which are the key to preparation of qualified glasses.

Second, choose the right eyeglass frames

First look at the appearance of the selected frame, the surface should be clear, have gloss, unblemished diseases, such as scratches, bumps, and corrosion. Second, look at welding is consistent, light weight, strong, not deformed. Selection should be based on those glasses face shape, skin color, age, size and degree of combination. Thus, the preparation of the glasses is not only beautiful, strife, decorative role.

Third, to measure accurately the IPD

IPD is the Ray Ban Wayfarer Glasses main parts. As we all know, the most important is when the glasses measure accurately IPD. Because the preparation of qualified glasses with IPD is closely related to the choice of frames is determined according to the IPD. Based on my years of clinical practice, you should first test between optometry IPD, and then select the frame, it would be consistent with the eyes and the IPD. If the frame shape suited to IPD, the optician can be appropriate in the process of shifting or relocation within the IPD will be equipped with IPD matching glasses. IPD is not accurate if the optical center of the deviation occurs, causing dizziness, diplomatic, or even cause a prism produce, causing serious harm to the eyes.

Fourth, when detailed examination of optometry

Optometry must first check whether the eye position, with or without mustangs, and congenital cataracts and other eye or other eye diseases. The glasses are glasses first if they have history, age, nature of work and habits with the eyes tell your doctor or optometrist. The eyes are the most sensitive organs of the human body, but also a kind of vision diaper most complex systems, the lens adjusting tension or spasm regulate use of the eyes produce tension. So, optometry physician or optometrist would need to determine the accuracy and glasses of cooperation.

Fifth, we should pay attention to the phenomenon after wearing

Initial wear Cheap Ray Ban Sunglasses wearers to begin some are not used, over 35 days will gradually adapt, this is very normal. Anisotropic glasses when teenagers are more common, especially anisotropic exceeds +3.0 D, the two images is difficult integration, when wearing corrective glasses, diplomatic, and do not wear glasses when different. Ophthalmologists called "visual noise" symptoms, therefore, in the process of wear, due to habits gradually disappear.

Current weary market was mixed, resulting in a lot of Ray Ban Outlet Sunglasses with quality problems, enabling consumers to physical and mental damage. So, how to get those glasses plainly achieve value for money too?

First, the medical guidance for first-time consumers who wear glasses, you must first understand the reasons for their vision loss, determine eye diseases caused by impaired vision, or by a change in refractive state of the eye caused by vision problems, to "doctors with integration", not blindly go glasses. Especially consumers wearing contact lenses must be equipped before the examination, expert guidance. Contact lenses are not available for all of the "one size fits all" and to avoid eye injury ruined eye.

Second, optometry right to go with a right glasses, optometry quite critical thing is to correct, so choose a suitably qualified expert or technician optometry, optometry obtain the correct prescription, which is very important. Consumer’s optometry to remain relatively stable mood and state of mind, so that the eye structure is in a stable state, can not be impatient and hasty.

Quality requirements for optometry shop should be: according to the customer's physical and psychological characteristics, give optometry prescription; in optometry process, with special attention to the darkroom radioscopy technology that allows the customer's eyes physiological optics feature lies in the rational optometrist operation, targeted to guide customers refraction; and through radioscopy techniques to understand the customer interstitial and refractive eye funds health; For caused by the pathological visual impairment, can provide suggestions to Customers go to hospital for eye examination, rather than "to one with a" pursuit of economic efficiency. Therefore, the optical shop staff, technical and professional ethics, requirements should be higher.

Third, processing excellent preparation of Ray Ban Wayfarer Glasses is a system process. After optometry, to select frames and lenses, for grinding machining, cutting edge is a highly technical process procedure. Therefore, consumers should choose glasses big name stores; they have a high-tech mulch-processing equipment and technical capacity to ensure processing quality. The big name stores should be in its reputation of excellence, to be worthy.

Fourth, the school with comfortable glasses, its physical optical characteristics of the eye will produce physiological as well as psychological positive and negative aspects of the role. This requires teachers to master this school with matching relationship between the sexes in this understanding height to carry glasses for every customer with the school, so that glasses are not only used as a tool for vision correction, but also a reflection of the personal attractive products.

Five, service Ray Ban Wayfarer Polarized glasses is not a mere commodity, its role is people's eyes. The human eye is a living body, a new environment there must be a process of adaptation, which would produce a human compatibility issues. Glasses may wish to take into account each person's ability to adapt to different, in line with the principles of coexistence of clear and comfortable, can be used for adaptive try new glasses can be adjusted within two months for reinsertion to ensure eye health.

The child matches the mirror, first must carry on an eye inspection, removes the intramuscular outside each kind of influence vision after disease, then carries on the optometry to match Ray Ban Outlet sunglasses. The optometry inspection first step disperses the pupil; the different age child disperses the pupil method to be different.

The purpose is to make migrate cyclopedia eye removed because the adjustment of children caused by too strong pseudo myopia, cyclopedia refraction data obtained is true degree of myopia. With mid-rise optometry degree obtained after selection of a child should be given the right glasses.

Glasses should note the following:

First, the degree of glasses prescriptions must be the same data on the same.

Second, according to the child face size and papillary distance, pick the right frames.

Third, geometric pupil distance and distance from the center line of the eye lens, lens transparent texture, no cracks and spots.

Fourth, wear glasses, should be presented with facial tilt angle of about 10-20 degrees, so not only easy to see distant objects, but also conducive to reading.

Glasses principles generally considered to be no visual impairment, ignoring fatigue, no strabismus and strabismus tendency, no trim Cheap Ray Ban Sunglasses.

1, on the vision loss problem: distance visual acuity and thus do not have to wear glasses.

2, hypertrophy glasses principles: public opinion that hypertrophy decreased visual acuity, with visual fatigue or isotropic and myopically, the need early glasses.

Children under 6 years of age with mild hypertrophy is physical in nature, and therefore do not have eyeglasses; such as hypertrophy is obvious, there is vision loss or appear isotropic, or 3-year-old children that should optometry Ray Ban Wayfarer Glasses.

6 a 16-year-old student, if any vision loss, visual fatigue or appear isotropic must promptly optometry.

Toddlers and young students of optometry, in principle, are carried out after the culinary muscle paralysis with atropine. Prescription degree obtained from radioscopy subtracted +1 D, to adapt to the culinary muscle tension, but there is isotropic or esophagi who should be fully corrected.
