The Importance of Protecting Your Eyes from UV Radiation

Many scientific studies show that prolonged exposure to sunlight without proper eye protection can lead to cataracts, eye growths, and even cancer. Based on these studies, ophthalmologists recommend wearing sunglasses with 99% or higher UV protection and a brimmed hat when spending long periods in the sun.

Appropriate sunglasses are key to protecting your eyes from the harmful effects of sunlight. They should be worn outdoors, especially in the following situations:

• During the summer, when UV radiation levels (UVA and UVB) are at least three times higher than in winter.
• At the beach or near water.
• When participating in winter sports, especially in high-altitude areas.
• When taking medications that may cause light sensitivity (photosensitivity).

The best sunglasses provide 100% UV absorption, offer optimal optical quality, and are impact-resistant.

Do Contact Lenses Protect Your Eyes from UV Rays?

If you wear contact lenses, they may not provide enough UV protection. Some contact lenses offer UV protection, but if your lenses don't block UV rays, you should wear sunglasses to safeguard your eyes.

Do Sunglasses Always Protect Your Eyes?

Sunglasses cannot protect your eyes from certain intense light sources. Exposure to light from sources like welding, tanning beds, snowfields, or directly looking at the sun, especially during a solar eclipse, can seriously damage your eyes. Viewing any of these light sources without proper protection can lead to corneal pain, known as photokeratitis, or even retinal damage, causing permanent loss of central vision. Your ophthalmologist can recommend the best measures to protect your eyes in these special situations.

By wearing the right sunglasses and taking additional precautions when necessary, you can help safeguard your eyes from harmful UV radiation and preserve your eye health for years to come.
