Pros and Cons of Polarized Lenses

When you’re shopping for a pair of new sunglasses, you might notice certain brands or styles have polarized lenses. Have you ever wondered about the pros and cons of wearing polarized lenses? Here are five facts you may not know about polarized lenses.

  1. NASA Jet Propulsion Laboratory developed polarized lenses after studying eagle vision. Eagles’ eyes contain a natural oil that prevents light from scattering.
  2. Polarized lenses were designed to reduce glare from sunlight that reflects off shiny or smooth surfaces like water, glass, chrome or asphalt (VisionSource.com).
  3. Polarized lenses don’t block UVA or UVB rays. Some polarized lenses also offer UVA and UVB protection, but not all. Read stickers and labels carefully.
  4. Polarized lenses can help increase eye comfort during activities like driving, skiing, boating and fishing (AAO).
  5. Polarized lenses might help you see better, but they shouldn’t be considered “healthier” for your vision.

If you live an active lifestyle and participate in outdoor sports, you may find that polarized lenses help reduce squinting and cut down on eye strain. But the most important feature to look for in a new pair of sunglasses is 100% UVA and UVB protection. Proper eye protection will delay degenerative eye diseases like cataracts and macular degeneration.
