The Benefits of Wearing Sunglasses

1. Prevent ultraviolet radiation from sunlight. 
Ultraviolet rays can damage the cornea and retina, and sunglasses can completely eliminate ultraviolet rays.

2. Prevent the exposure of strong light.
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. Sunglasses can filter out up to 97% of the light that enters the eye to avoid injury.

3. Prevent glare.
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. Sunglasses can use polarized light technology to eliminate such glare.
