What To Look for in Sunglasses for Eye Health

In a recent blog, we discussed why sunglasses are so important for protecting your eye health. Today, we want to discuss what to look for in a good, protective pair of sunglasses. In addition to looking fabulous, your sunglasses should protect your eyes from damaging UV rays. Here’s how to pick the best shades for your summer eye health:

Always Check the UV Protection

Select sunglasses certified to block 100% of UVA and UVB light from the sun. Some sunglasses have labels that mark “UV absorption” rather than “UV blocking.” In that case, look for labels indicating “UV absorption to 400nm.” Blocking UV radiation from your eyes can prevent damage to your eye lens and cornea, protecting you from many vision-damaging problems like macular degeneration and cataracts.

How Dark is Too Dark?

Just because sunglasses are dark doesn’t always mean they block 100% of the unwanted UV rays. Sometimes, darker glasses can cause extra eye strain because your pupils will dilate too much, causing additional light sensitivity and aggravating circumstances for people who struggle with migraines. Our eye doctor in Champaign, IL says medium-dark sunglasses are sufficient for daily use. Again, the most important thing to look for is UV blocking!

Size Matters

The larger the lens, the more protected your eyes are. Not only do larger lenses block more UV rays, but they can block dust and pollen too, which is great for people with allergies. Wrap-around sunglasses are especially protective.

What About Polarization?

Polarization and UV protection are two totally different things, but you may need both. Polarized lenses are designed to lower excess glare from water, snow, sand, and other bright, reflective surfaces. This is great for activities like boating, fishing, and skiing. That said, polarized glasses are not good for low-light driving or trying to read LCD screens.
