Blue Light Explained
Macular Degeneration Blue light (HEV) penetrates all the way to your retina and has been shown that too much exposure to blue light can damage light sensitive cells in the retina. This causes changes that are similar to those of macular degeneration, which can lead to permanent vision loss. Many eye care professionals have concerns that the blue light exposure from digital screens might increase a person's risk of macular degeneration later in life.
Digital Eye Fatigue Short wavelength, high energy blue light scatters more easily than other visible light and makes it not as easily focused. When you're looking at your digital screen that emit significant amounts of blue light, this unfocused visual light reduces contrast and can contribute to digital eye strain.
Sleep Disruption Blue light is very important in regulating circadian rhythm - your body's natural wakefulness and sleep cycle. Exposure to blue light during daytime hours helps maintain a healthful circadian rhythm. But too much blue light late at night can disrupt this cycle, causing sleepless nights and daytime fatigue. People who use their electronic devices before bed have a harder time falling and staying asleep.
Why Not Block All Blue Light?
It's well documented that some blue light exposure is essential for good health. Research has shown that high-energy visible light boosts alertness, helps memory and cognitive function and elevates mood.
In fact, something called light therapy is used to treat seasonal affective disorder (SAD) — a type of depression that's related to changes in seasons, with symptoms usually beginning in the fall and continuing through winter. The light sources for this therapy emit bright white light that contains a significant amount of HEV blue light rays.
Also, blue light is very important in regulating circadian rhythm — the body's natural wakefulness and sleep cycle. Exposure to blue light during daytime hours helps maintain a healthful circadian rhythm. But too much blue light late at night (reading a novel on a tablet computer or e-reader at bedtime, for example) can disrupt this cycle, potentially causing sleepless nights and daytime fatigue.

I just hung it right on and it fits perfectly! I love it, I can’t quite break my habit of falling asleep with the tv on in my room but at least I feel better about blocking the blue light at night and you can tell it works! Customer service is excellent as well! Highly highly recommend.

keeps your eyes from blue light as it describes. It is a little too small for my screen so have an inch on each side, but it is ok

It fit my tv perfectly and was very easy to install, even for a senior lady. Just one thing to be aware of, the sticky pads that it came with didn't work very well. I had to use additional sticky tape that I had. Overall, it works well and does not change the color on the tv.

I have a LG 55" TV. with a small border. But when you place the bent part of the shield over the top of the TV (which is easy to do), the bottom of the shield does not cover the bottom 3/8" of the TV screen. The width is OK, but the bottom looked bad. Also, the glare from this sheet is even worse then the TV screen. I bought it for the anti blue light only, which is all this shield was stated to be, but the glare was really bad. The shield is only 1/16th in. thick and fairly flimsy. I should have sent the shield back at this time, but I tried some things to get the shield to lay lower on the TV, and I ended up cracking it. It cracks very easily. So I gave up on sending it back. Now I am out $130. So this review was written to make me feel better about the money I lost. I settled for a $15 pair of blu-blocker glasses even though I don't see as well at the distance the TV is from me.

I initially got this because I have been getting headaches, and I was suspect of monitors. I’m not so sure that I really needed it, but I will say that it’s probably more gentle on the eyes anyway so I decided to keep it.It fit right on the face of my television (corner to corner) and you can’t even tell that it’s on there unless you tell someone. My daughter thinks that it does change the color of the television screen a little little bit but honestly, I really don’t see that as an issue

Except it does overlap my tv but I like that it gives it a cool design

There is a glare but my tv is on a rotating table so I can change the angle. Using it before bed, I turn off all lights so this is not a problem for me.

This blue light topic has pros and cons, and everyone will make their choice. The real facts, science, and medicine need more research. It is believed LCD and LED TV emits very low blue light and no UV rays. Yes or No? Regarding the glare issue, we had members detect glare, which irritated their eyes for quite a few hours. Some of us wear blue light-blocking glasses and did not find this. So we had to return this screen. Our only con is that we wish it had a tucked-over top to snap onto the TV frame. So, you must use the holding product enclosed with the screen. We decided to turn the backlight/ brightness down on our TV so it was not as bright.

I ordered both the 55 inch and 43 inch. However, the 43 inch was broken upon arrival. The business refunded it which was great. The product is amazing. I re-ordered the 43 inch and the order was cancelled. Just messaged the business to see if they could resolve the problem. Apart from that, the product is amazing and I hope I could get the 43 inch soon.
