Do these filters block out uv lighting? If so, how much and does it block both uva and uvb?

Sorry, but I'm not sure. I purchased them to soften the lighting in my classroom.

No uv light in this model. My old filter that was a different style and brand had a uv light and I dont think it did any good

Also, cost about $25 t0 $30 from iSpring. Free shipping and cheaper by the pair. They also sell sets of 3 years of filters except for the UV lamp. Best deal I have found.

I always have a UV or skylight filter mounted on my Canon lenses, purely as protection for the lens from either dust or damage. The hood can be screwed directly onto the filter and it does not effect your pictures.

i'm not sure, it doesn't mention anything about UV filters anywhere on the box.

It will block UV but I don't know about blue light. You cut it to fit screen.

not sure on the exact UV protection rating- They are up at our cabin 4 hours away so I can check on them, but they are a dark smoke tint and protect great against the sun- Since I had lasik eye surgery my eyes are very sensitive to the sun and they work great0 the best is how they keep the dust out without fogging- I actually bought 5 pairs just to have for everyone that rides with us!!

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.

I have ordered these glasses and tested it with 2 different UV spectrums. I have found it blocked 395nm but not so much for 365nm To 370nm wavelengths. I tested this by holding the UV light(s) then putting the glasses in front of transitional lenses on glasses.

UV(C) passes much more ultraviolet light than UV(0) filters. Additionally, the Pro 1 coating is a little more transparent and easier to clean. Finally, the Pro1 rim is higher quality. See hoya's website below: http://www.hoyafilter.com/hoya/products/generalfilters/uvcslimframe/

Some models come with a UV filter and some don't. As I ready had a stand alone UV unit, I bought the cheaper unit w/o UV filter. I would hope that the product specifications, based on the size of the unit, would include that information. Sorry, but that is the best I can do.

Ive found these to be very nice filters. No glare that wasn't already existent in the lens to begin with. No UV filter will wipe out all glare or lens flares that are already from the lens. The key is to not add any more of its own.

You can order them from the filter manufacturer but they have a real attitude problem in my experience. I got extras through AMAZON. Just type in UV bulbs and order the one you need. They are good for a year of effective use, mine will be replaced soon, installed last July.

Not sure. I wasnt too concerned because my regular glasses have both UVA and UVB protection.

The UV filter blocks Ultra Violet light which in certain situation can cause pictures to blur somewhat. They can be useful at high altitudes or places with very clear air. They are often used as a clear filter to add a layer of protection to the lens glass as the filter is cheaper to replace. The polarizing filter will filter out polarized light and glare. Its great for shooting in sunlight and will make colors much more vibrant (saturated.) I live in a desert area and never shoot outside during the day without one.
