Prescription Glasses

Sunglasses are one of the eye vision care products which can be used to prevent the intense stimulation in the sun from hurting our eyes. With the improvement of people’s material and cultural level, sunglasses can also be used as one kind of adornment or cosmetic to reflect the personal style.

Prescription sunglasses are one of the best ways to enable the wearers of corrective eyeglasses to protect themselves from harmful UV rays outdoors. As with non-prescription sunglasses, your primary concern when buying prescription sunglasses is that the lenses block 100 percent of the sun’s harmful UV rays. UV protection is unrelated to the color and density of the tint in sunglass lenses, so you can choose any lens color and darkness you like.

You can choose the tinted lenses or photochromic lenses to change your normal eyeglasses to be prescription sunglasses while tints are the permanent colors on the lenses, and the photochromic lenses can darken outdoors and resume being clear indoors. Besides, clip-on sunshades which can be removed conveniently is also a good choice for prescription sunglasses.

Prescription sunglasses are available in all lens materials, including high-index, polycarbonate, regular (CR-39) plastic and glass. Though glass lenses arguably provide the best optical quality, they are no longer the most popular choice for sunglasses. This is because they are much heavier than lenses made of other materials, and they can shatter easily. However, they are still available if you request them. The polycarbonate lenses will help your prescription glasses to remain more durable because the polycarbonate lenses have better impact resistance. You will also get many other advantages with these lenses. They are more durable and they do not weigh that much.

The dazzle beautiful sunglasses makes you active in the sunshine. Actually the sun glasses can withstand the sunshine but it can not hold pollution and damage, so the maintenance of sunglasses becomes very important.

The method to maintain the prescription sunglasses is as the same as the ordinary glasses. But since you take on or off the sunglasses quite often which will cause the glasses easily scratched, there are some small details to remind you: when the sun glasses have stain adherent, please don’t use your fingernail to dig it which would easily scratch the surface of the prescription glasses.
