The role of sunglasses

 

Ultraviolet rays can damage the cornea and retina, and high-quality sunglasses can reduce the damage of ultraviolet rays to the eyes. When the eye receives too much light, it naturally shrinks the iris. Once the iris contracts to its limit, people need to squint. If the light is still too much, such as the sunlight reflected by the snow, it will damage the retina. And high-quality sunglasses can filter up to 97% of the light entering the eye to avoid injury.

 

Some surfaces can reflect a lot of light, such as water. And the bright spots produced in this way will disturb the line of sight. High-quality sunglasses can use polarized light technology to completely eliminate such glare.

 

If sunglasses do not provide UV protection, it will expose you to UV radiation. Cheap sunglasses filter out part of the light, which causes your iris to open to receive more light. This also allows more ultraviolet light to enter, which increases the damage caused by ultraviolet light to the retina.

 

Therefore, there is a difference between various sunglasses. According to the specific use environment, choosing the right and high-quality sunglasses will provide you with maximum protection.

 

According to international standards, sunglasses are classified as personal eye protection products. The main function of sunglasses is to block dazzling sunlight. The international standard subdivides sunglasses into "fashion sunglasses" and "general sunglasses".

 

The quality requirements for "fashion sunglasses" in the standard are relatively low. Because the most important thing about "fashion sunglasses" is style, the wearer focuses on decoration rather than protection. The standard has stricter requirements for the quality of "general sunglasses", including the requirements for UV protection, diopter and prism.

 

The requirements for prescription sunglasses are even higher. Because prescription sunglasses are specially formulated sunglasses based on the optometry results of the wearer. The lenses of prescription sunglasses are not flat, but can correct myopia, hyperopia, astigmatism or presbyopia.
