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) โ 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 โ 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.

The video instructions and instructions that come in the package are not the same. Very confusing. I just made it work.

I was told that one possibility why my left eye has AMD -and I go monthly for a shot IN that eye, so it doesn't progress further..... is because I've been using a TV with no Blue Light protection, for 9 months.So, I spent an evening researching the best blue-light screen for my 32" Samsung TV, which I use as my PC Monitor. I've learned through the years the best methods for installing screen-protectors for cellphones.Aha....! This one sets up a VERY similar method to the one for the easiest installation of cell-screen protectors. :-) "Anti-Blue Light" comes inserted in a TUBE box, so no travel-wrinkles. Pull out the baggie with a helpful squeegie for the next-to-last step (and some tiny CELLPHONE screen cleaners & dust removers: pretty useless, since you are cleaning a large TV screen....). Also provided is a circle of the TAPE ALREADY STUCK AROUND THE SCREEN -to use if you MESS UP and have to place fresh tape around the screen, to try "Install effort #2." Fear not: Simply follow these instructions (after watching the short manufacturer's video on Amazon, within the item's info: by a lady with a red top). Wash your hands.Before unboxing the blue-screen, get a microfiber "Ultimate Cloth" (or a cloth to clean eyeglasses) and WET, then squeeze, that cloth. Wipe it firmly over the entire screen, both vertically and horizontally. Let it dry. Shine a flashlight on it to see if any dust shows & just TAP the provided dust-remover over any dust-dots. Then pull the Blue-Screen itself out of the tube-box. You will see that the tabs to REMOVE the two plastic "entire screen covers" are already affixed & labeled (Red side is removed BEFORE -& Green, AFTER positioning the screen). 1st, place the Anti-Blue-Light Protector ON your clean screen, with all tabs & covers still attached. Be sure it FITS! If not, send it back & remeasure, then reorder.If it fits...simply but CAREFULLY (without touching the now uncovered side of the Blue Light Screen) pull OFF the "red label side" layer and the 4 pieces of thin brown tape, from around the 4 edges. Next, position the sticky top & 1 side so that your TV Screen is exactly parallel vertically & horizontally, to your Blue Screen....then press it on, firmly pulling the provided, white plastic presser OVER the still-attached Green tab's cover, as you smooth the Blue Light over your clean TV screen, to the other edge. Make a pass with the white presser OVER the 4 edges, now stuck to your TV Screen. Then simply use the Green tab to gently pull off the top cover (embossed all over with "Anti-Blue Light" in green....). Voilร ....! You now have a screen that saves your eyes from Blue Light - and glare; the colors and contrast on your screen should seem as before - and mine do. I'm really glad I selected this "easy-install" Blue-Light protector. :-)

The screen was the wrong size, half an inch shorter than the screen on my standard 32" monitor. Because this screen needs to be pasted on the monitor screen, this mentally handicapped way makes me face the embarrassment of leaving a seam on each side of the screen every day. I didn't choose to return it because it was already glued to my monitor, and if I had to tear it off, I was worried that it would damage my monitor, or there would be glue left on the screen that wasn't cleaned properly. I don't want to face these horrible things anymore! Don't buy don't buy! Don't buy this, if I had to choose again, I would choose to buy one that hangs on it, not on the monitor!

Happy so far with the product. It would be nice if the seams from the glue were not visible on the edges of the screen (do understand how that would be a challenge). Unsure at this point if it has helped my eyes at all, but there is no glare and I can see my screen perfectly both for video and for my studies, in which I use dual screen regularly and have had no challenges.

Any source of light caused a glare that made the screen almost impossible to see. If I watched TV only in the dark, maybe this would work. Returning.

Really like this filter, super easy to install,no bubbles, no colour distortion. I find it much easier to fall asleep maybe a placebo effect but it works for me. Very happy with the purchase.

Does the job well. I wished the size of the protector is wide enough to stick on the edges of the screen rather than the screen itself though. Maybe should have a proper edging that could hang on the screen instead.
