Are these glass UV protective?

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

I believe they are Polymer, too light to be glass & a good buy for the money...JMO... I keep a pair on my book case & one on the garage work bench and a pair out in my shed...lol...

Well generally sunglasses says on the glass that it has UV protection in this case it does not say anything about it, the I lost the manual where I could find something. However the sunglasses are excellent, comfortable and my wife is very happy

They look like they could be plastic glasses, but they aren't. The set we have is all glass. They are very nice glasses and they have no issues in the dishwasher.

I believe they are glass. They certainly appear to be. I have the polarizing filter permanently attached to my Nikon 7700 and I'm very happy with it (esp. considering the price).

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.

Hi Sandra, I'm not sure about any UV issues regarding the usage of these lights. There are numerous studies on the benefits of the red lights and blue lights. I would suggest asking the seller. Good luck.

Unless the manufacturer has changed the glass in the last year or 2, the answer is no. Mine are clearly stamped on the bottoms, "Not for use in oven" .

Yes. There is some UV protector on them. They will still yellow eventually though.

I'm not sure if they block all UV and Blue rays, but they are awesome especially for the price. I look at a computer screen at work constantly and when my eyes start to hurt, I put them on and it really helps. They are nice looking too.

yes. I have had mine for three months and use them on my glass top regularly with no problems

This product (and I think any pair of safety glasses with polycarbonate lenses) offers 99.9% protection against UV-A and UV-B. UV-C would come from things like germicidal lamps, and I believe the recommended protection for that kind of exposure (if more than for a few seconds) is a full face shield, not just safety glasses.

No, but all of the lenses block 99% of UV light, and the dark ones do help with reducing glare. I am actually using them as sunglasses.

I'm sorry, I don't know. I've thrown away the boxes they came in, but I remember lots of symbols and remarks about the product on the outside of the box. However, I don't remember about UV protector.

If you are referring to a case and in plastic then yes they are protected. I received mine on time and haven't had any problems so far.

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