Polarized lenses have:
1.a higher radiation blocking protection percentage: 100% of any radiation up to 400nm that far surpasses the legal requirements of both the US and EU.
2.a lower transmission: only 15% of visible light reaches the eye
3.up to 100% protection from reflected glare

6.each lens is extremely strong and resistant, withstanding the Drop ball test :a 5/8 inch steel ball dropped onto the lens from a height of 50 inches,which makes the optical glass impact resistant even at the lowest thickness. Plastic lenses have a natural impact resistance that is similar in strength to crystal and even more.
