Does it block harmful UVA/UVB Rays?

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

I don't like to say it, but I didn't like the sun visor extender. I gave it away. It was just a bother.

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

While I agree with the other response that it does not stick all that well to the window (make sure you put the right side to the window), nevertheless I am grateful for it. I use it on my side windows and just stick it up into the window crevice. It is easy to put up and down. In this way I can have protection from the sun in the front and side. I have no idea if it blocks the UV rays; I just need blockage from the sun in my eyes while driving. I use it all the time.

Yes, it does, & it's pretty good, too! I went to the dermatologist after using this product daily for over a year, & she could tell that I was using sunscreen...something I didn't start using until my mid 30's, & only with this product. Enjoy! :)

Yes blocks light well. I don't know about acne. I do recommend cleaning regularly to avoid catching and giving colds. I'm sure that would help with acne as well. Also I wouldn't recommend wearing too tightly. I noticed my vision was blurred for a few hours after wearing tightly.

No I dont think it does. I think it is just the fabric itself that has some measure of UV protection. I have had some of these us for 5 or 6 summers now and they are holding up well - and the UV here in Albuquerque (mile high altitude) are intense. They block most, but not all, sunlight which would leave plenty to grow anything here, even say flowers.

Yes it does. They are frosted and will protect against the UV Rays just as well as Amber, Green, or any other color.

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

From my experience, it doesn't. It made the skin tighter only in places and is not effective under the eyes.

I suppose that indirectly it is, but it mostly blocks the damaging rays and then needs to be washed off. I wear it because I'm allergic to some of the ingredients in most regular products.

anything will block a UV ray. even a clear plastic lid will block the rays. I did an experiment in my microbiology lab where we exposed two plates with bacteria to UV light. One plate was covered by a clear plastic lid and the other was not. The bacteria on the exposed plate had no bacteria growth because it was killed by the UV, the plate covered by the clear plastic lid did have growth. The lid provided adequate UV protection even with the plastic being clear. As long as the rays are being interfered with by something, they cannot be absorbed, whether it be clear, opaque or solid.

I don't believe this product contains mexoryl which is the best UVA absorber. It's now just like any other chemical sunscreen without the strong UVA protection you get from mexoyrl SX and SL. But what mexoryl does to prevent UVA damage is to prevent tanning. If you tan, you get skin damage. There's no way around that. I use self tanners if I want a tan. I still buy Anthelios with mexoryl SX and XL but it's harder to find than in the past.

It's supposed to block 95% of UV rays. The Shade Sail comes with large D rings at the corners and 3 pieces of nylon rope. I just hammered a couple of nails into the face of my front porch to hook two of the D rings and tied two pieces of the rope together to tie the 3rd end to a Palm Tree

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!

I purchased the dark tinted skylight and strongly assume it does block some uv light. I have not tested it to be certain.

The specs say that is has UV protection however I am unsure how to tell exactly.

It looks like what you are asking about is the sun screen. It is a moisturizer, but I only apply it on skin exposed to the sun and use the non-sunscreen moisturizer on the rest of my body. SPF 30 is adequate for most UVA & UVB protection.
