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.
