Sun Glasses
Dec 26, 2018

Sunglasses are a kind of eye care products that prevent eye damage caused by strong sunlight. With the improvement of people's material and cultural level, sunglasses can be used as a special accessory for beauty or personal style.


Since the sun's rays reaching the earth's surface contain ultraviolet rays, the cornea and crystals of the human eye are the most vulnerable to ultraviolet rays, and "cataracts" are closely related eye diseases. Due to the destruction of the ozone layer by the environment and the increase in outdoor activities in summer, the damage of ultraviolet rays to the human eye cannot be ignored. Wearing sunglasses is a good way to protect your eyes from UV damage, but pay special attention to sunglasses.


In accordance with international standards, sunglasses are listed as a category of personal eye protection products, because sunglasses are worn in the summer, the main function is to block the glare of the sun. However, international standards have subdivided sunglasses into "fashion mirrors" and "general purpose mirrors." The quality requirements for “fashion mirrors” are relatively low in the standard. Because the "fashion mirror" mainly highlights the style, the wearer pays attention to the decoration, not the protection function. The quality requirements for “General Purpose Mirrors” are more stringent in the standard, including requirements for UV protection, as well as diopter and prismaticity.
