Does Crystal offer UV protection?

Actually I'm not sure but if they don't say so then I guess not. It is a completely closed system so I'm not sure how sunlight could effect it either way. Hope that helped.

No, but I have found that using these crystals consistently has improved my skin tone with less visible wrinkles on face and neck and chest. Your question does intrigue my curiosity. Let us ( Amazon customers ) know if you try the 2 products together, your results.

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."

Yes but it has no UV protection so how long is it going to last..not very long.

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.

The particular ones I purchased, anti reflective clear lens, do not. They are for safety only in a work type setting. However, glancing at some of the other colors such as blue mirror or smoke it appears that those do offer UV protection.

Your tv does not give UV radiation. You are concern about electromagnetic radiation, this film will not affect that.

Yes it has UV protection! It blocks out more sun than it looks like it would! I absolutely love this cover!!Don't know the weight but it's not really heavy! We covered our percula with it! Love it!

The Ultra Crystal one does not, nor does the Ultra Oleophobic. The Ultra Fine and the Ultra Optics do somewhat affect the "crispness" as basically any matte protector will.

Yes. There spectrum includes both UVA & UVB. I use them to help both my reptiles and live plants get the light they need.

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

Website says blocks UV rays from up to 400 nanometers? Here's the link. http://www.bolle.com/technology/goggle/technology

UV has a light wavelength below that of the visible range. Since these lights are all within the visible range (minus the red which has part of it in the IR), there should be no UV rays.

I'm not an expert, but to my knowledge, lens protection is main purpose. No added value to photo using clear glass. Since it's an extra layer of glass, there will be very slight impact on light transmission, but I certainly don't have a finely calibrated eye to see it with my camera and photo's I shoot. If you already have UV filter on your lens, you don't need to add NC.

I just received my order. Right on the side of the box for Model DPG28 it has a label that says: "99.9% UVA-UVB Protection." Can we please just retain what we "think" and only share what we know? I was wondering this same thing before I ordered, and the comment below almost caused me to not purchase them. Then I figured that it would almost be impossible to have darkened lenses that don't offer any such protection, so I looked it up online and found a vague answer saying that they did offer some kind of protection. Very pleasantly surprised to see that they offer such thorough protection!

I do want to help but it will be better to contact the manufacturer. What I know is to be carefull with uv rays produced - no uv rays on your skin, not either on your eyes, bear eyesglass protecting uv, follow the manufaturer's rules. It is a wonderfull machine.
