Do the lens block Ultra Violet?

yes they do but the music part after a while screws up and the buttons all do reverse things

not sure but you can't beat the price and the sound quality. I use them for golf. Sometimes the buttons are mixed up but still work. I have a pair of Oakley thumps and the quality difference is obvious as the price reflects.

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.

Probably. These lenses are made of Lexan, which is a polycarbonate plastic. According to Wikepdia: "Polycarbonate is commonly used in eye protection... Polycarbonate lenses also protect the eye from UV light."

I have several pair of dark sun glasses, that's why I ordered these "shooting" glasses. They have 99.9% UV Blocking, that's what "fries" the retina, not the bright light. I "hate" dark sun glasses for anything beyond fishing from a boat in bright sun shine - then I can see through the dark lenses. I understand these yellow lenses are also good good at night -I had a pair but seldom drive at night.

From what I can tell the outer covering is not the lens, but rather a UV filter of some sort. The lens itself is far behind the outer covering. So the lens is protected by default. I don't know the camera (yet) but I have been researching it a great deal and am knowledgeable about cameras.

It should be fine if you blacken the whole lense the foam blocks light for sure.

yes they work great. I use them when I ride my motorcycle and they are tinted along with uv protection which makes everything clear and my eyes don't hurt even after being on the highway in the sun all day. Are they safe around a bright welding light no they don't take the place of welding shield but they work for daylight.

No, only clear lens, if a blue filter is added it would have to be glass. The lens gets very hot.

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

The issue is UV light. https://www.macular.org/ultra-violet-and-blue-light quotes 400nm as the cut off.

They have an IR-3 or IR-5 rating and an ANSI Z87.1 that requires listing the UV protection level but I couldn't find it anywhere on the goggles or any sites offering them. I use them for glass and metal working but you might hold off using them for UV until you know for sure. Most IR rated optics do block UV but I'm not sure if that's intrinsic. It's the opposite end of the spectrum that these are explicitly designed to protect your eyes from.

There is an outside thread on the lens so it should be possible to fit a UV filter to it.

no, it's an inexpensive purchase but can save you mucho bucks if you scratch or break the lens. it also helps eliminate ultra violet rays and a bluish cast when shooting in bright sunlight.

With a minimum focal length of 18mm you likely need a lower profile filter than this. A UV filter generally has no tint but is treated to reduce the effects of UV rays and will brighten colors.

Not that I have seen. They r the only ones I use anymore and always keep 2 to 3 pair extra in case I loose or break ones I am using. Have not seen a difference in lens color. If you buy the folding bow ones that r as seen on TV they r much darker and very uncomfortable.

Not that I know of. Even with SLRs I have found that if you see lens flair you can usually just stick you hand out and block the sun.

No. Lens hoods block lens flare, which has nothing to do with the polarization of light.
