Complete SUNGLASSES Information - What they should do

Sunglasses should screen out 75% to 90% of viable light. Sunglasses should be dark, but light enough that you can see your eyes in a mirror. Look for a uniform tint, although Double Gradient Tinting (extra tinting at both the TOP and the BOTTOM, can help reduce glare). Sunglasses are marked with a FILTER CATAGORY from 0-4, where 4 is the darkest lens. Being dark does NOT ensure good UV ray blockage. Coatings to block UVA/UVB/UVC rays are COMPLETELY TRANSPARENT - how dark sunglasses are, does NOT effect how well they block Ultra Violet (UV) rays. Sunglasses should block 1) ultraviolet A, 2) Ultraviolet B AND 3) BLUE LIGHT (400-500 nm) Finding one that also blocks Blue Rays will be the most difficult. Wrap-around sunglasses are recommended (although they do not look as good) Polarization helps with glare (only). Mirror Coatings are good.

BLUE LIGHT (HEV = 400 to 500 nm) May help Cause Macular Degeneration

New research suggests the sun's high-energy visible (HEV) radiation - also called "blue light" - INCREASES your risk of macular degeneration. HEV rays have longer wavelengths (than UV) - 400-500 nm. Blue Light and Macular Degeneration "It hypothesized that people who have plenty of melanin and don't tend to burn easily are at less risk for macular degeneration than people who burn easily or are bothered by by sun glare."

Sunglasses - Wikipedia How Sunglasses Work UV light is broken into three different types: UVA, UVB and UVC. UVA = wavelengths(320-400 nm). Slightly blocked by the Earth's ozone layer. UVB = wavelengths(280-320 nm). Strongly blocked by the Earth's ozone layer. UVC = wavelengths (100-280 nm). Very Strongly blocked by the Earth's ozone layer.

UV400

UV400 Blocks all UV rays from 100 to 400 nm (UVA, UVB plus UVC). BUT THEY DO NOT PROTECT AGAINST BLUE LIGHT (HEV = 400 to 500 nm), which is suspected of being 30% responsbile for Macular Degeneration. eBay Guides - What Is Ultraviolet UV 400 Protection BluBlocker.com HowStuffWorks "Cheap vs. Expensive Sunglasses" How to travel with sunglasses and eyeglasses on an airplane How Do Sunglasses Work? - knowledge for protecting eyes Sunglasses - Wikipedia, the free encyclopedia How Do Sunglasses Really Work?
