Does this block UVA and UVB
326028
The label reads "Broad Spectrum" sunscreen, which I believe covers both UVA & UVB rays. I used this on my 2 children for a week at the beach this summer & neither got burnt, and my 1-year old got no sun tan at all while using it, so I am sure it covers both types of rays. I found this sunscreen on the Environmental Work Group's "A" list of sunscreens for 2012. It worked very well for us. Hope this helps!

I don't remember this product. I did note someone mentioned the product leaving their face somewhat white. If you are out in intense sun, you need a block that is more protective like this one. My favorite right now for everyday use is Eltamd UV Clear SPF 46.

I am not totally sure of that answer, I just figured it was like clothes, if its covering up you aren't getting the full impact of the UV light, just like when you are out in the sun, your clothes protect your body. I think its better than not using them at all.

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

It does not state that anywhere on the couple that I have at home. However, we used it all winter and had no issues with blocked pores! Hope that helps!

No it does not. Water and air pass through, it provides about 90% uv protection and shade.

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.

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

I always wear sunscreen so I don't notice any UV issues, but the lights made my eyes feel uncomfortable and I read reports that this may be harmful to eyes so I seldom use them now. It does work on skin problems though.

We now have a product called "Ray Bloc for Clothing". It is intended to protect the skin from UV damage by blocking UV penetration through treated clothing.

It blocks blue light regardless of it's source, artificial or natural. And I just got my UV meters out and for instance the total UV (UVA + UVB) measured was about 1.6mW/cm^2 and UVB alone measured 113 uW/cm^2. With the glasses placed over the sensors they measure 0.00mW/cm^2 and 4uW/cm^2 respectively. The UV meter also measures 4 indoors so I think the that is a calibration issue and it is really 0 for UVB. UVB is easily blocked by plastic even if not tinted. So I would say the answer is yes, it blocks UV and blue light.

I never tested it so I am assuming the UVB passed through since it is a thin plastic and I would have hoped the manufacture did test that. Also I felt it was safer to have a protective barrier between the water and the light tube just in case. UVB does pass though plastics and some glass but may be "diluted" or refracted and depending on the thickness and the clarity of the material it can be blocked completely. Also UVB does dissipate with distance so you need to read the details to ensure it is placed appropriately. Hope this helps....

No it would not block sunlight, though it would partially block it. It's made of a fairly thin plastic.

It is supposed to provide UV protection. My experience to date is so limited that I cannot confirm this. I used this product to actually stiffen a fabric that I used for kites that was more porous than I wanted. I would check any fabric with this product in an inconspicuous place before using just to be sure I was satisfied.

The product states, 'an optimized combination of photostable UVA/UVB filters' so I assume yes. I really like it on my face as it does not clog pours, it soaks into my skin, and doesn't remain greasy. I don't mind paying a little extra for this product as it was recommended by my Mayo Clinic physician.

I have no idea if they will block UV...Asking the wrong guy this time, sorry.....

I primarily use this product on my face and sometimes my chest but you could use it all over. Pretty expensive for that purpose though. Also, when I buy this product I always look for the version that has a orange 50 on the label and says uva/uvb protection. The product pictured here is slightly different and doesn't offer broadband protection.
