Beyond Cool: Which Sunglasses Protect Your Eyes from UV Rays?

Which Sunglasses Protect Your Eyes from UV Rays?

Admit it: You like to wear sunglasses because they make you look cool. But an even cooler benefit is that if you buy the right kind of sunglasses, they’ll protect your eyes from exposure to the sun’s harmful UV (ultra-violet) rays, which can lead to vision problems, some of them quite severe.

How can the sun damage your eyes?

The sun’s UV rays can damage the cornea, lens, and other parts of the eye and over the years can cause cataracts, cancer of the eye, or skin cancer around the eye or on the eyelids,” according to Intermountain Riverton Hospital optometrist Jefferson Langford, OD. “They can also cause an abnormal pink tissue on the white of the eye called pterygium.”

What kind of sunglasses should you get?

Sunglasses recommended by the American Optometric Association have:

  • Lenses that block 99 to 100 percent of both UV-A and UV-B rays
  • Lenses that screen 75 to 90 percent of visible light
  • A frame that fits close to your eyes and contours to the shape of your face to prevent UV exposure from all sides. Wrap-around frames are best.
  • Both lenses perfectly matched in color and free of imperfections

Prices for lenses that meet those standards can vary a lot. Some are relatively cheap and others can be expensive, so it pays to shop around. Be sure to replace your sunglasses if the lenses get scratched or warped.

What are the advantages of polarized lenses?

Polarized lenses reduce reflected glare when sunlight bounces off snow or water. They’re great for skiing, snowboarding, water sports, fishing, or driving. Check with your eye doctor for lens color and shade recommendations.

Should children and teens wear UV protective glasses?

“Children’s eyes are more transparent than adult eyes, which makes it easier for UV rays to reach a child’s retina. Children and teens are typically out in the sun more than adults, which makes them more susceptible to UV damage,” says Dr. Langford.

Why should I wear UV protective sunglasses?

Preventing cataracts

Protecting your eyes from UV rays while driving may help prevent cataracts. Side windows in cars often aren’t as shaded as the windshield, and a recent study found that UV exposure from driver-side windows may lead to a higher incidence of eye disease.

Can your eyes get sunburned?

“If your eyes are exposed to excessive amounts of UV radiation over a short period of time, you’ll likely experience photo-keratitis or ‘sunburn of the eye,’” says Dr. Langford. “It can be painful.”

Symptoms of sunburned eyes:

  • Red eyes
  • Feeling like something is in your eye or a gritty sensation in the eyes
  • Extreme sensitivity to light
  • Excessive tearing

Fortunately, these symptoms are usually temporary and rarely cause permanent damage to the eyes. See an eye doctor if you have these symptoms.

When should you see an eye doctor?
