Be careful: The cheap sunglasses damage the your eyesight

The cheap sunglasses are very harmful, especially for children . If your child does not have quality glasses, it is best not to wear glasses.
Sunglasses have become more like a fashion accessory and eye protection became secondary. Despite quality sunglasses are much more expensive than the cheapest that can be found even in a kiosk, but the fact is that sunglasses should not skimp.
So beware! The cheap sunglasses can “kill” their eyes. Plastic through which you see, unless properly, it does not protect from the sun’s rays also distorts vision because the eyes are also exhausting, and can lead to visual impairment. Such sunglasses are especially sensitive to children, so it is best not to use any lens.
When buying a pair of glasses should look out for the following:

The glasses should primarily protect your eyes from ultraviolet radiation. The cheap sunglasses do not have that protection or protection is very low quality and has little effect.
As the lenses must be labeled on the percentage and type of radiation that block. The most important thing is not to miss out ultraviolet rays. In addition, if the glasses writing that they are “polarized” that does not necessarily mean that the protection from UV radiation – “polarized” means reducing sun glare areas around us

There are sunglasses quality, you can simply check out the following.

Put the glasses, find your field of view of a flat line and staring at her. Close one eye and slowly move, move his head up and down and from left to right. Repeat with the other eye. If the goal is quality, then the line is at all times be flat, otherwise, the glasses are not that quality as the seller claimed.
