About polarized sunglasses:
What are the benefits of using sunglasses
Ultraviolet rays can damage the cornea and retina, and high-quality sunglasses can completely eliminate ultraviolet rays.
When the eye receives too much light, it will naturally shrink the iris. Once the iris shrinks to its limit, people then need to squint. If there is still too much light, such as sunlight reflected from snow, it will damage the retina. High-quality sunglasses can filter out up to 97% of the light that enters the eyes to avoid damage.
Certain surfaces, such as water, can reflect a lot of light, and the bright spots produced in this way can disturb the line of sight or hide objects. High-quality sunglasses can use polarization technology to completely eliminate this kind of glare. We will introduce polarization technology later.
Certain frequencies of light will blur the line of sight, while other frequencies of light can enhance contrast. Choose the right color for sunglasses to get better results in a specific environment.
If sunglasses do not provide UV protection, it will expose you to more UV rays. Cheap sunglasses filter out part of the light, causing your iris to open to receive more light. This will also allow more ultraviolet rays to enter, increasing the damage caused by ultraviolet rays to the retina.
Therefore, there is indeed a difference between various sunglasses. For a specific use environment, choosing suitable and high-quality sunglasses will provide you with the greatest protection.
According to international standards, sunglasses are classified as personal eye protection products. The main function of sunglasses is to block the dazzling sunlight. However, international standards subdivide sunglasses into "fashion mirrors" and "general purpose mirrors." The quality requirements of the "fashion mirror" in the standard are relatively low. Because the "fashion mirror" mainly focuses on style, the wearer pays attention to decoration rather than protection. The standard has stricter quality requirements for "general-purpose mirrors, including requirements for UV protection, as well as index requirements for diopter and prism.
