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.

It was a bit tricky to attach to the TV with its adhesive edges, but we succeeded and now it is invisible and I am aware enough to state that the TV leaves me with much less eye strain. There is not the lingering bright spot from the screen if I go into the darkness right away after watching for an hour or so. This is a way to keep your eyes healthy.

The screen protector is glossy and produces a bad screen glare.It doesn't stick to the screen; there's essentially a bubble behind the entire thing with adhesive on the edges. Therefore, the screen is noticeably less clear when looking through the screen protector.The blue light filter is pointless because you can just adjust the color balance of your screen to reduce blue light.The only thing it's good for is scratch-prevention.

This product is a total joke. If I could give it zero stars I would. The adhesive comes off of the screen when you try to remove the paper. The screen is too small. Bubbles galore. Once I got it on the TV (as much as I could) I could no longer even see the TV. I pulled the film off and literally threw it in the trash.

Bought this for the bedroom television. It was easy to install, but after about a week, the screen fell off the TV. Have put it back on several times, but not sticky enough to stay. Duct tape seems to be working to hold it on. For the price, I didn't expect it to not stick after a week.

I installed this exactly according to the instructions - the film has sticky edges that attach directly to the screen . After about two weeks I found that the pixels on the screen had died where the film stuck and since then this has spread right across the screen. I would advise caution when using this product, and am very upset that my TV has been permanently damaged and now may have to be replaced.
