Polarized lenses can protect one's eyes from much of the sun's glare while providing the same UV protection as regular non-polarized lenses. Working to filter horizontally polarized rays, e.g., reflections from surfaces like water and cars, polarized lenses enhance one's visual experience by reducing glare which increases clarity and contrast.

 

Eye strain, otherwise known as asthenopia, is a condition that can result from excessive exposure to glare. 

 Symptoms Include: 

•  Possible blurred vision 
•  Burning sensation in the eye
•  Watery/Dry eyes
•  Headaches 

 

In short, if you drive/boat/fish/hike/go outside, polarized lenses are the lenses for you.
