What is UV Radiation?

Ultraviolet rays are powerful invisible light rays that are present in sunlight. Specifically, there are three forms of UV radiation including UVA, UVB, and UVC rays. Both UVA and UVB rays have wavelengths shorter than visible light and these are the most harmful to your health.

Moreover, prolonged exposure to UV rays can result in several health risks such as premature aging, skin cancer and damage to the eyes. That’s because the sunlight’s rays can pass through the eye’s cornea and reach the lens and retina inside of the eye.

The Impact on the Eyes

Anyone who spends time outdoors in the sunlight is at risk for vision damage, especially if you aren’t wearing protective eyewear. In particular, prolonged overexposure to UV radiation has been linked to the development of some types of cataracts. Also, research shows that increased sunlight exposure may play a role in the development of macular degeneration. Other eye issues that can occur include:

  • Cancer
  • Blurred vision
  • Solar retinopathy
  • Sunburned cornea
  • Irritation and redness

Keep in mind it doesn’t have to be summertime (or even sunny outside) in order for UV rays to affect your vision. Although the sun’s rays are the strongest between 10 am and 2 pm, UV rays can penetrate clouds. Thus, it’s possible to experience sun damage to your eyes even on overcast days. So, whether you’re relaxing on the beach in August or skiing on a mountain in January, UV radiation is present.

Shopping for Sunglasses

Protect your eyes from the harmful effects of UV rays with proper sunglasses, hats, and wraps. In fact, wearing sunglasses that block 100 percent of UV rays is the best way to protect your eyes from the sun. Specifically, the folks at Looking Glass Optical suggest close-fitting, wraparound frames to limit sun exposure. You should also choose a pair of lenses that darken instantly in the sun. Not to mention, polarized and mirror-coated lenses increase comfort as they reduce glare from bright light, as well as limit the amount of light entering your eyes.

On the other hand, finding the right pair of sunglasses for your face shape and style preferences can be challenging. If you can’t find sunglasses with UV protection that suit you, don’t worry. You can always add a polarized coating to the pair for 100% protection from UV radiation.
