Consumer Reports in their latest magazine, Feb. 2016, says these "Uvex Skyper safety eyewear (orange tint) - cuts out almost all blue light. The Gunnar Intercept gaming glasses (med. yellow) block half. Spektrum Pro Blue Light Blocking Glasses (light yellow) only by one third. "

Yes they are but look at this model too. I found them a lot more comfortable. Uvex S1933X Skyper Safety Eyewear, Black Frame, SCT-Orange UV Extreme Anti-Fog Lensby Uvex

I just received a pair today and used a color spectrum test image (and I'd tried others as well). Here's a link to it if you're interested. https://www.paleohacks.com/sleep/will-plain-red-or-orange-lenses-block-blue-light-for-sleep-17104 These were the only glasses that showed true blue blocking. I'm thrilled as I spend way too many hours under fluorescent lighting and in front of a computer screen. At my my age I couldn't care less whether they're stylish or not. I do like the S1933X though, better for comfort... lightweight.

It blocks up to 540nm light and the specification for the specific tint says that it blocks greater than 98% blue light. See page 14 of http://www.uvex.us/uploadedFiles/ProductConfiguration/ProductLiterature/Uvex_Lens_Tech_Update2011.pdf

I haven't tried True Blues but I LOVE these gloves. I have never had any color or allergy issues & my skin is pretty sensitive. You can reuse these until you wear a hole in them. I absolutely recommend them over any other brand hands down!

Yes they are. all the nanoblocks are. But the reason that is, is because its mostly pictures. you have to be able to perceive the different layers. Its easy once you figure out the way it works. I have about 15 sets.

I was of the impression that they werent, info on amazon & also the bluedio site does not state they are. But the sound level & quality is that good Noise Canceling doesnt seem necessary to me! love them :) They ae over ear & super comfy. Certainly gives a feeling off the outside world being blocked out. hth!

They're not blue at all... They are actually white. I wouldn't trust these controllers. I have 2 and both change from auto to manual controls at random.

They are blue but see-through. If you don't need to see the colors of the contents accurately, they may work for you. However, if the colors of the contents are important, it is a dark enough blue that it will create problems.

Yes to the blue light blocking. I use them only at the office to decrease frequency of headaches from overhead fluorescent and LED lights. Don't know about improved sleep.

I'm not sure of that answer as I only bought one pair and I don't even remember which number. They have a faint yellow cast to them that blocks the blue computer glare. They work really nice.

I'm not sure. However, if you t=go to the BlueAnt Website, myblueant.com, you should be able to find all the information you need. Hope this helps.

No, and I have cataracts. They are just plain eye drops and Iv'e read that the blue color that isn't FDA approved won't hurt your eyes.

Yes, they are. However, I strongly advise you not to buy them. I purchased eight of them and they all worked for about 4 months then they because bloated and became very difficult to remove from the camera once inserted. This didn't happen worth the genuine ones. However, If your goal is short term you should be fine.

I don't know, but the blue lettered ones have worked well enough for me that I am going to order another batch

Yes, I have used the old Bluettes and the True Blues are just as good. I love that they now come in colors. The top portion of the glove is lightly textured to prevent slippage. These gloves are the best! I can handle anything that is really hot with my True Blue gloves on - including peeling hot beets that have just come out of a steaming pot. You can use this product with confidence.

I do not know which blue ones you are referring to (I have seen more than one in blue), but I have seen these for about $25 and about $50. They work like they are supposed to. I like them a whole lot better at $25.

Nope. While not stylish in the least, these are GREAT at blocking out the blue light. Perhaps if you did a handstand, a bit of light might leak in from under your eyes. But apart from that these are great. I wear them on my drive home from night shift even if I look ridiculous. :)

Not really sure what you mean by "They all look alike." All of the blue ones are the same and they are quite deferent from any others. When I wear them I do not hear my husband snoring, etc. The only drawback is making sure your ears are clear of any residual wax. I totally love them and will order them again.

I ordered several and got the gray blockers which work fine for me. I've given them to friends and family and they all love them.
