What Are Sunglasses?

Sunglasses are glasses used to protect the eyes from the ultraviolet rays emitted by the sun. These rays can cause significant damage inside the eye.

Usage Guidelines

It is advisable to use sunglasses:

During summer at noon, because the level of ultraviolet rays is three times higher than in winter.

Near reflective surfaces, such as glass, metals, and snow, as these are areas that reflect more ultraviolet rays, which can reach up to 80%.

On the beach, because water and white sand can also reflect large amounts of harmful rays into the eye, which can reach 15% due to the sand and 25% due to the water.

When it is cloudy, even when clouds block the intensity of sunlight, high levels of ultraviolet rays can pass through them.

Frequently Asked Questions

What should you look for when buying sunglasses?

Choose sunglasses that block 99% of ultraviolet rays and have a label indicating “100% protection against both UVA and UVB rays.”

Buy large-sized sunglasses with a wide frame if possible. The more coverage sunglasses provide, the less harm the sun’s rays will cause to the eyes.

Ensure the lenses are polarized, containing a filter that protects the eyes from the glare resulting from the reflection of sunlight on flat surfaces.

Beware of counterfeit sunglasses, as their lenses do not protect against harmful sun rays; instead, they concentrate the rays on the eye.

Does the difference in lens colors and the cost of sunglasses play a role in protection against ultraviolet rays?

The difference in lens colors and cost does not play a role in protection from ultraviolet rays.
