Polarized vs Non-Polarized Sunglasses

Eyewear has drastically evolved since the Inuits fashioned sunglasses out of walrus tusks. However, the driving force behind that evolution remains the same: protecting delicate eyes from the bright sun. Advances in technology have replaced Walrus tusks with high-performance lenses and presented us with the option of purchasing polarized or non-polarized sunglasses. The difference is nearly invisible to the naked eye unless you're the one sporting a pair of polarized shades. Why should you care what type of lens you have? Here's what you need to know:


What are polarized sunglasses?

The difference is in the lenses. Polarized lenses minimize glare before it reaches your eyes. Non-polarized sunglasses decrease the intensity of light hitting your eyes, but they do not filter out glare. Polarized lens glare reduction makes it possible to gaze below the surface of calm water and improves visibility when driving. 


Are all polarized lenses equal? 

No. Cheap polarized sunglasses are engineered to fail. Low quality polarized lenses will wear down or peel off with use, which means you need to buy more. Our modern polarized sunglasses feature a lens "sandwich," meaning two extremely thin lenses are secured on each side of a polarizing filter. The result is very lightweight and protects the polarization, so it never peels off.


What makes polarized sunglasses work?

The sun's light travels in waves that bounce up, down, left, and right. When the sun's light hits a flat surface (like bodies of water, the hood of your car, or the road), the light waves all begin to bounce in the same direction. This intense concentration of light is what causes a visible glare. Polarized sunglasses are like blinds for your eyes. They only allow essential light waves to pass through, improving visibility and preventing eye strain. 


Why use polarized vs non-polarized sunglasses?

Non-polarized lenses make it easier to see in bright conditions, but they do not reduce the harsh effects of glare. Polarized sunglasses make it easier to see in bright conditions with the added benefit of blocking unnecessary glare. Polarized lenses:

  • improve visibility
  • improve clarity
  • reduce eye strain
  • provide an accurate perception of colors
  • increase contrast

Additional information to consider: If you are an airplane pilot, non-polarized sunglasses are recommended due to the optical qualities of plane windows and controls.


How do I know if sunglasses are polarized?

Put the sunglasses you are testing on and look at a bright, reflective surface like a car or window. Tilt your head 60-90 degrees to the left or right. If you notice that the glare appears and disappears, the sunglasses are polarized. Another method is to find a second pair of polarized sunglasses. Look through both pairs simultaneously, stacking them on top of each other, and tilt the front pair 90 degrees to the left or right. If both pairs are indeed polarized, then you won't be able to see through both lenses. The lenses will appear to be blacked out.
