Glasses can not be arbitrarily

Experts, with Ray Ban Outlet Sunglasses correction should be based on the principle of low-grade, such as wearing 350 degrees or 400 degrees of myopia, vision correction can reach 1.0, and you should choose 350 degrees of myopia. In optometry when corrected visual acuity of 1.0 as a standard, not in order to allow for unlimited corrected visual acuity increased to 1.5 degrees to avoid optician 1.5 vision. At the same time the same myopic astigmatism. Some people plus astigmatism, the feeling of dizziness, visual distortion, vision correction should not affect the case, reduce or remove astigmatism, a process of adaptation to the eyes, three or six months after the addition of astigmatism. High myopia can not accept all corrective glasses, should be wo low glasses, to be adapted and then increase the degree, the degree increments should not exceed 300 degrees.

In addition, in real life for many elderly people do not pay attention to wear old mirrors, just buy a pair of glasses to wear. Elderly should be how to choose, configure an appropriate old mirrors it? Best to the formal, reputable optical shop to find a qualified optometrist and inform their glasses use, according to the optometry prescription, with their own face, parameters and prices to pick the right glasses frames and glasses, Ray Ban Wayfarer Polarized shops will follow optometry prescription parameters and requirements for processing production, the finished glasses, the indicators should be consistent with the national standard requirements. Buy old mirrors in the field, experts remind to by professionals help to ensure that the selected optical center of the old mirrors horizontal distance with their IPD match.

The following is a summary of some professional experience, for your reference:

1, hypertrophy: Average to the highest number of best corrected visual acuity better. If a child has hypertrophy and isotropic associated symptoms, must wear corrective glasses full.

2, astigmatism: mild asymptomatic do not glasses. If decreased visual acuity, visual fatigue, and mild symptoms should be prepared regardless of the right glasses. High astigmatism and axial deflection, the patient is not easy to accept, may be appropriate to reduce the diaper. Astigmatism is wearing all the general principles of corrective glasses. Astigmatism in the audition piece is sure to pay attention to axial adjustments. Often axis potentiometer 50 will affect vision correction. Can not be discharged, visual fatigue symptoms.

3, myopia: Request to minimize refraction, best corrected visual acuity, wear appropriate Ray Ban Wayfarer Glasses. (If the patient is not in use regulation case, use-5.000D corrected visual acuity was 5.0 when used with-4.50D adjusts audition corrected visual acuity was 5.0, generally with-4.50D glasses better.) To avoid overreaction, (especially near more patients from work) cause visual fatigue symptoms. High myopia glasses for the first time, the patient can not accept all the diaper correction. May be appropriate to reduce the diaper to adapt over time, and then to increase it.
