Buy New Glasses Online

The first principle of buying a pair of prescription is that wearers should buy eyeglasses with the smallest degree to achieve the best corrected visual acuity. This is a very important principle. For example it is same of wearing a -150 lens or -200 lens that you can get the same vision correction to 1.0, you should choose the -150 lens.

Optometry 1.0 can be achieved when vision has been corrected, not to pursue the non-corrected visual acuity increased to 1.5 degrees and without restriction.

Those with mild astigmatism may be corrected to give low-grade. And some bad feelings,like dizziness, discomfort may come about after patients who have add astigmatism. Without compromising visual acuity wearers can get the lower astigmatism lens or even not to purchase this kind of lens, giving the eye an adaptation process, and to add later.

If it is the first time for a high diopter of myopia suffers to buy prescription glasses, but can not accept all of these corrections for eyes, they shall elect the eyeglasses with low diopters. Once they have adapted the increase in diopters, you can buy the deeper one, but each increase should not more than 300 diopters.

For wearers who have different eye diopters of two eyes, the regular eyeglasses might not be able to get a good binocular vision, can only be fully corrected degrees lower one. Wear contact lenses and effective. For patients with irregular astigmatism that normal lenses are difficult to correct, so they can try on contact lenses.
