Are Your Sunglasses Doing Their Job?

Summer plans may be cooling down, but temperatures are still rising!  That big yellow thing in the sky is hitting temperatures of over 100 degrees here in Arizona.  Before you set off to buy a new pair of styling shades, let us fill you in on a few quick facts to help you find a pair most beneficial for your eyes.

Sunglasses help protect your eyes from a few different sunrays, including Ultraviolet rays (UVA) and UVB rays.  Here’s what you need to know about these potentially harmful exposures:


  • Ultraviolet rays remain at the same intensity all year long. Regardless of the season, these rays mean business!
  • UVA rays cause more damage to our bodies than UVB rays.
  • Even short exposures to UVA rays while commuting to or from work can cause noticeable damage.
  • Many doctors say that it only takes around nine moderate doses of UVA rays to experience a noticeable change on our bodies.


  • UVB rays are also known as “tanning rays.”
  • These rays are strongest in northern hemisphere’s summer months or when sections of the Earth orbit closest to the sun.
  • UVB rays are only strong enough to penetrate the very top layer of our skin.Now that you know the basics, don’t forget these additional facts when shopping for a new pair of sunglasses:
  • Choose a pair that is 99-100% both UVA and UVB protected.
  • Avoid sunwear referred to as “cosmetic.” It won’t give you the protection you need from the sun.
  • Larger lenses > smaller lenses (they protect more of your eye)
  • Wearing tinted glasses doesn’t necessarily protect you from the sun’s rays. In the same token, clear lenses can offer UVA and UVB protection. Stop by your local Nationwide Vision Center, and we will help you find a pair that works best for you.

Now that you know the secrets to picking out a fully-protected pair of sunglasses, double check your current pair and make sure your lenses are doing their job.  Remember too that although hats are recommended in sunny weather, you should still wear your sunglasses for true eye protection.
