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.

Worked as designed... Have to remember to take the protective strip off the edges for it to stick to the screen.

It only has a adhesive on 3 of the 4 sides and its less than 1/4 inch of adhesive on those 3 sides. Its not enough to keep the protector flat. It bubbles. Other protectors I have purchased have the entire back aligned with adhesive. This will not work very well.

Once I got it cut to fit so my laptop would close, it works good. Helps to cut down glare and can still use my touch screen, easier to clean than my laptop screen too. Actually gives me a little lip to grab to open my computer easier.

Although this product does block the blue light as advertised, it is horrible with the glare factor. I cannot use it.

Disappointed this is not truly anti-glare. Advertised as both anti-glare & anti-blue light. This may reduce blue light, but the glare is worse than before putting it on. Do NOT recommend if you need anti-glare!

This product is absolute and utter garbage. It is completely unfit for purpose.The protector uses actual 3M tape to stick to the screen - I am NOT using glue that may not be removable on a very expensive screen. I cut it off but it does not (unlike iPad or iPhone protectors) stick to the monitor without that 3M tape.Second, the protector makes the screen incredibly blurry. Like glasses they have never been cleaned. Like looking at the screen through a foot of steam.I don’t understand how this is even on the market. What a waste of my time and total disappointment.
