TrueDark Junk Light Dots - Sleep Hacking Blue Light Blocking Stickers That Filter or Blackout Lights on Small Electronic Devices - LED, Clock, TV - Protect Your Eyes From Harmful Blue Light

I had a pack of these from a Biohacked box and after moving, couldn't find them. Our new home has these annoying remote switches on the wall that emit a blue light. They were so bright, they kept us up. I tried ordering from Biohacked, but they were out and was thrilled to find them here on Amazon. One of the black dots and our annoying light is covered. I have used these to cover lights on power strips and the flashing green light that smoke detectors have. When I still want to see the light, I use the red or white, but it helps soften them enough to not be annoying, Great product!

Need some much bigger stickers for some of the exterior lights, but helped to cover some of the brightest white lights. Tailgate camera light has some heat to it, so sticker not staying on as well as I would like. The stickiness could be better, but not the worse; they do eventually want to peel off. Again, I would love to find some 8" x 10" sheets of the red film to cut my own sizes.

In the age of consumer electronics their are bright led that can ruin a perfectly dark room. These are life saver and should be included in nearly all consumer electronic product.

We used these stickers to darken all the little lights in my infant son’s room when we started sleep training and they did the trick! Haven’t needed to use the red ones yet but the black ones work really well.

these little transparent stickers work well to block out the little blue lights on almost anything electronic…the router light, alarm clock face lights, extention cord lights, etc.

Love the concept but they simply didn't work. Applied to cable box LED light and none of the 3 stickers worked, meaning the LED light was not visible clearly through the stickers. Increased the LED brightness on cable box and could barely make out the number still.This is a good company but they need to come out with a new film that works like the glasses do, where you can see through it but block the blue light... if they do I'll buy that but these definitely do not work unfortunately...

Love these! They definitely help to block all the little lights on things that create a poor sleep environment.

These did not stay in place! It was so frustrating. I would put them over the l blue light on my tv and in a few hours they would no longer be adhered to the surface. So frustrating.
