Comparing Polarized Sunglasses vs Non-Polarized Sunglasses

By Stacy Schanks 1 comment

If you think all sunglasses are made equal, think again. At some point of your shopping experience, you’ve probably seen sunglasses, labeled as “polarized lenses” and others non-polarized. To the average consumer, the words can be confusing. What exactly is the difference between nonpolarized and polarized sunglasses?  Is it worth paying extra for polarized lenses? We breakdown the differences between polarized vs non-polarized sunglasses and the benefits of polarized sunglasses so you can make an informed decision on what pair to buy for yourself. 

What are Polarized Sunglasses?

Originally, polarized sunglasses were developed by NASA to protect astronauts’ eyes from space radiation, nowadays you’ll most likely find it a permanent facial accessory on many adventure enthusiasts.

Polarized sunglasses contain vertically polarized filters which counter the sunlight from reflective surfaces, such as cars, roads, or water. By countering the light, it greatly reduces the glare of the surfaces. When light is reflected off of water or solid surfaces, the reflected light shines back at your eye and is magnified which results in a glare. Polarized lenses filter the light that comes in from different angles and allow you to view objects clearly. 

Polarized vs Nonpolarized Sunglasses

It’s important to note when you put on a pair of sunglasses, the darkness in colors causes your pupils to get large. When this happens your pupils widen allowing more light to enters your eyes, making it easier for UVA and UVB rays to enter. These rays are extremely bad and may lead to macular degeneration and some cases of vision loss. Polarization has nothing to do with UV light absorption, but many polarized lenses are now combined with a UV-blocking substance. Check the label to make sure the lenses provide maximum UV and UVB protection. While normal sunglasses reduce the brightness of an environment, Polarized lenses reduce glares. Polarized lenses filter the light that comes in from different angles and allow you to view objects clearly. 

Non-polarized lenses don’t filter light in this way, so the glare is much more noticeable. 

Without polarized protection, depth perception is reduced, distorted view and color perception occur, and in some cases, you could be temporarily blinded, when trying to focus. 

The Benefits of Polarized Sunglasses

  1. Help Reduce Eye Strain- All that reflective light will help you not squint when you wear a pair of sunglasses. When you squint, it’s a side effect of eye strain.
  2. Increase Clarity - The removal of glare allows you to see things you wouldn’t have seen otherwise, especially around water, which why many marine sports enthusiasts wear them.
  3. Enhances Contrast - With no glare, contrast, and depth perception is enhanced.
  4. Color Perception Enhanced - Colors appear more vibrant and brighter

When To Wear Polarized Sunglasses

  • Driving – Always wear polarized vs. non-sunglasses when driving because the lenses help cut out any glare that may be dangerous to the driver. 
  • Fishing – Glare reflects very easily off of the water’s surface so polarized (vs. non-polarized) glasses are the best option when out on the water.
  • Biking – Polarized sunglasses can prevent any harmful glare from distracting the biker and potentially endangering them or others.

When Not To Wear Polarized Sunglasses

  • Flying An Airplane – Pilots are advised to wear non-polarized sunglasses while flying because polarized lenses can sometimes make it difficult to see, and especially to read the controls and GPS in the cockpit.
  • Skiing – When skiing, glare actually helps to distinguish the snow from ice. Therefore, skiers can see where to continue their path and avoid dangerous situations.
  • Operating heavy machinery – This is because certain polarized lenses can make it challenging to see the controls or GPS screens used in these situations.
