The ultraviolet rays in summer are the strongest. If you do not take protective measures, your eyes will be hurt, and the retina, lens, conjunctiva, eyelids, etc. will all be injured by ultraviolet rays. Sunglasses can reduce the damage of strong sunlight to the eyes and the dazzling light which can cause headaches. Sunglasses have a filtering effect of 95-100%. So people must wear sunglasses in summer. What are the benefits of wearing sunglasses?

The benefits of wearing sunglasses

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

2. Prevent exposure to 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.(https://www.koalaeye.com/collections/polarized-sunglasses)

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.

4.Eliminate light of specific frequency. Certain frequencies of light can blur the line of sight.

How do sunglasses protect your eyes from the sun?

Excessive ultraviolet rays in the sun can damage the cornea, which is medically called corneal epithelial peeling. Exfoliation of the corneal epithelium can cause pain and foreign body sensations in the eyes. Inflammation of the cornea can occur when the protection is not performed properly. Long-term strong light stimulation may not only damage the lens to cause cataracts, but also damage the fundus retina to cause macular degeneration. In addition, too strong sunlight can cause acute damage to the eyes, such as snow blindness, which is the outer layer of the eyeball that is burned by ultraviolet radiation after a large area of snow (or clouds, calm water) reflects sunlight. Its typical symptoms are eye pain, dryness, tearing, gritty foreign body sensation, skin redness, conjunctival congestion, edema, etc.

Do children need sunglasses?

Children can wear sunglasses. For children under 6 years old, choose sunglasses with lighter colors. Children’s eyes are delicate and easily damaged by strong light. In this case, children need to wear sunglasses. But it should be noted that children under the age of 6 are not suitable for wearing sunglasses for a long time. Because their visual function development has not reached the adult level, wearing sunglasses for a long time may cause amblyopia. Therefore, children should wear sunglasses correctly when the sun is strong but take them off when the sun becomes weak.
