The Benefits Of Wearing Sunglasses

If Sunglasses don't provide UV protection, they can expose you to more UV light. Cheap sunglasses filter out some of the light, causing your iris to open to receive more light. This also allows more UV rays to enter, increasing the damage they can do to the retina.

Therefore, there is a difference between the various types of sunglasses. Choosing the right, high-quality sunglasses for the specific environment will provide you with the most protection.

According to the regulation of international standard, sunglass is listed as the category of things for personal eye protection. The main function of sunglasses is to block the glare of the sun. However, international standards subdivide sunglasses into "fashion mirror" and "general purpose mirror". The quality requirement of "fashion mirror" in the standard is relatively low. Because "fashion mirror" is primarily about style, the wearer pays attention to decoration rather than protection. The standard has more stringent quality requirements for general purpose mirrors, including UV protection, as well as index requirements for diopter and prism.
