Why Wear Sunglasses in Summer?

1. Prevent dust from entering the eyes

The air is dry in summer, and the air contains a lot of dust and impurities. If it enters people's eyes, it is easy to cause allergies to the eyes, and it is easy to cause symptoms such as eye discomfort. Wearing sunglasses can effectively prevent dust from entering the eyes and protect the eyes.

2: Prevent strong light exposure

When the eye receives too much light, it naturally contracts the iris. Once the iris shrinks to its limit, then people need to squint. If there is still too much light, such as sunlight reflected from snow, it can damage the retina. Sunglasses can filter out up to 97% of the light entering the eye to avoid damage.

3: Prevent ultraviolet radiation in sunlight.

Ultraviolet rays can damage the cornea and retina, and sunglasses can completely eliminate ultraviolet rays.

4: Prevent glare exposure

Some surfaces, such as water, reflect a lot of light, and the resulting bright spots can distract from sight or hide objects. Sunglasses use polarizing technology to eliminate this type of glare.

5: Eliminate light of a specific frequency. Certain frequencies of light can blur vision.

In general, wearing sunglasses is not only to look cool, but more importantly, to protect your eyes.
