Why is harder optometric vision correction

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.
