will these cling to a tv screen (the yellow ones)in order to block blue light at night and sleep better?

They will cling to the screen but the light shines through. I didn't try it over blue light but I putt it over the computer screen and it doesn't block out the light.

They are suppose to, but I haven't ever tried! I have used them up, so I can't try it for you before you purchase them, sorry!

I'm no expert, but this is what I would recommend. Wipe your TV screen with a damp cloth while the TV is turned off. Apply the cling on sheet to the glass screen. Will cling to glass only. Good luck!

I'm not sure if they block all UV and Blue rays, but they are awesome especially for the price. I look at a computer screen at work constantly and when my eyes start to hurt, I put them on and it really helps. They are nice looking too.

Yes, they do block the sun like blue blockers and the wrap around works well. Definitely worth the purchase at such a great price. Since they are not made by "Blue Blockers", they may not want any legal issues if they advertise them as such.

Yes, my wife watches tv at night and the flickering light of the tv bothers me so I started pulling the band over my eyes. It helps block out the light and still stays on all night.

No, these would be terrible at night. However, they are great during the day, especially for driving. What you're looking for is something like this HD Night Vision Wraparounds Wrap Around Glasses

Not really, but they don't diminish the visibility, either. I was using a mirrored screen saver and I couldn't see anything on the screen in bright daylight. These are barely perceptible.

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.

Yes, these completely block blue light. Several of my electronics have a blue power light and it is not visible when wearing these. They're safety glasses and come with certification that they block blue light, like for welders.

Yes, but after 3-4 hours of use they lose brightness and turn blue.(See my previous comments on this item)

I would think that it would. While you would still see the sunlight filtering through, it should be "thick" enough to help with glare. We have a nightlight behind the screen and it looks nice at night with the light behind...

As long as your TV uses "passive" not "active" 3D technology, they should work.

I have not tried these at night. I use them primarily for bird watching, for which they are excellant. But this is what I will; tonight or tomorrow night I will take them outside and see how they work in "low-light". Tom

I use them for night and rainy driving, and I think they're very good at brightening things up. I don't know if they block blue light completely, because I haven't anything to compare to. I just know they work for me and I have a pair in each vehicle.

No Richard. My experience is it will not do much to diffuse bright light at night. The product is very effective in blocking vision into the home in the daytime, but at night it is the reverse. It allows everything and everyone a clear sight line inside the home. If you want to completely keep light out of an area, I would suggest blackout curtains. I've use them for years because I am very UV sensitive and they block 95% of daytime light and 100% of night light. There are many styles, sizes and price options are very reasonable, they work, and they really help to reduce heating and cooling cost. Hope this helps. Elaine

No,not completely.There is about a 1/2"gap,so it may be enough to to put your laptop in sleep mode.They stay in place when using them, and are removable when done.

No. These cut down peripheral glare but they seem to intensify light sources such as oncoming headlights. At least that is my experience. Perhaps a different owner has had better results with night glare.

I'm not sure, I use them to watch TV at night. I believe they're suppose to b/c that's what the TV projects & can keep you awake at night. They do help me feel sleepier earlier in the evening when I wear them before I go to bed & watch TV.
