Do these glasses protect from UV rays?

Don't know. I use them for my patients in the dental chair. They're light weight, and easy to clean.

According to 3M, they protect from 99% of UVA and UVB rays. http://www.shop3m.com/3m-virtua-protective-eyewear-ap-11815-00000-20-gray-hard-coat-lens.html?WT.z_bynt=1

According to product pages on other websites, "Polycarbonate Lens provides impact protection. All lenses provide 99.9% UV protection."

Yes it does. They are frosted and will protect against the UV Rays just as well as Amber, Green, or any other color.

I use these as sunglasses for events I wear them to, they do a good job blocking the sun b/c of the dark tint. However, they have no UV protection and partially block your peripheral vision. And don't wear them in shaded areas, they're too dark to see well in anywhere other than daylight.

I do not know. However, windshields do block UVA rays. I do not know about the other rays.

They block and protect your eyes when using Black Light/UV. They would only enhance when using the "light" as far as contrast on urine.

No I dont think it does. I think it is just the fabric itself that has some measure of UV protection. I have had some of these us for 5 or 6 summers now and they are holding up well - and the UV here in Albuquerque (mile high altitude) are intense. They block most, but not all, sunlight which would leave plenty to grow anything here, even say flowers.

The most widespread protection is against ultraviolet radiation, which can cause short-term and long-term ocular problems such as photokeratitis, snow blindness, cataracts, pterygium, and various forms of eye cancer.[9] Medical experts advise the public on the importance of wearing sunglasses to protect the eyes from UV;[9] for adequate protection, experts recommend sunglasses that reflect or filter out 99-100% of UVA and UVB light, with wavelengths up to 400 nm. Sunglasses which meet this requirement are often labeled as "UV400."

Unsure. I bought them specifically to protect my eyes from UV lamps operating in the 254nm range.

I did a lot of research before buying these and I was told they do not. The package says nothing about UV protection. I am 99% positive that they are only to protect the eyes from flying darts.

No they dont. I put them on when facing the sun and it's like not wearing glasses at all. These don't offer protection from sun just from computers.

its harmful ultraviolet rays - same as when you purchase sunglasses with ua protection

I don't know exact numbers on the UV protection but they definitely keep the sun out so I'm sure the UV protection is pretty strong.

The website says they have UV400 protection. (Global Vision Eyewear, Escort AST)

I'm sorry, I can not answer that question, as I do not know. I can tell you these are my favorite sun glasses ever! I have bought three pairs, I love them. And highly recommend them.

My thought was yes. UVC is a short wavelength and that is why it is blocked by our atmosphere. So it is easily blocked by glasses and probably plastic as well, especially plastic that we know blocks UVA and UVB rays. Here something from Wikipedia: Ordinary glass is partially transparent to UVA but is opaque to shorter wavelengths, whereas silica or quartz glass, depending on quality, can be transparent even to vacuum UV wavelengths. Ordinary window glass passes about 90% of the light above 350 nm, but blocks over 90% of the light below 300 nm.So with resonable confidence yes they block UVC, which is what germicidal lamps put out. Watch out for your exposed skin though. My thought was yes. UVC is a short wavelength and that is why it is blocked by our atmosphere.

No, but they are wide and soft/flexible so I don't think it will be an issue. These glasses are awesome
