The Use and Maintenance of Sunglasses

According to the suggestions of eye experts, we should wear sunglasses regularly to protect our eyes because the lens of our eyeball is easy to absorb ultra violet radiation. And the damage of ultra violet radiation has two specific features: The damage of ultra violet radiation can be accumulated. For the ultra violet radiation is invisible, people is difficult to feel it directly.

Then the UV on the eye injury is irreversible, which can not be repaired. Long time injury will cause the damage to cornea and retina, and until the cause of cataract lens opacity, lead to permanent vision damage. Because UV damage is invisible to the eye, not immediately be able to feel it. If you don't usually wear sunglasses and feel easy, that just shows your eyes are not sensible to visible light (such as glaring light, reflective light). But the ultra damage can not be avoided.

So we should wear sunglasses regularly to avoid the damage of ultra violet radiation. But how should we use and maintain them? A pair of new purchased sunglasses should be adjusted by the counter staff. Leave the store unless you feel comfortable. When you put away your sunglasses, you should put the left temple before the right one away. When you take off the sunglasses, you should grasp the temples in front of your face with both hands. When you don't wear your sunglasses, wrap them with cleaning cloth place in a special bag to avoid the lenses and frames being scratched or squeezed for a long time by hard items.

If the lenses and frames of your sunglasses are stained by dirt, sweat, grease, cosmetics, etc. Please clean in warm water with a mild detergent, and then dry the water on the lenses and frames with dry soft cloth. Your sunglasses mustn't be put in water, soaked in water and placed on a fixed place exposing in the sun. And they shouldn't be put near the electric current or metal. It is a natural phenomenon that the plate of sunglasses may be slightly deformed after using or setting aside some time. It depends on the attribute of the plate material. You can get them adjusted as new in the dealer. If you take care of your sunglasses in right and diligent ways, they will be durable and lasting.
