After the four corners are picked up, grab the lower corner and pull up. Then the whole screen protector will start to loosen, and then pull up the four corners until it is removed. Congratulation: the task of removing the old screen protector is now completed. At this point, the screen protector will automatically stick to the screen and slowly expand to the surrounding area. Take out the squeeze card, press the edge from the top to the bottom, and drive the bubbles away.

Anything above 380 nanometers is not visible to the human eye and cannot be seen. While invisible, these frequencies can still be useful. Some epoxies used in dental work use ultraviolet light to accelerate the chemical process of fixing teeth. Tanning beds use these frequencies to artificially increase tan color (though of course you wouldn’t want to be bathed in it for hours, or you could develop significant health problems).
Dry eye can result in a series of problems with your eyes apart from making your eyes irritated or itchy.

Blue light exposure may increase the risk of macular degeneration. The fact that blue light penetrates all the way to the retina (the inner lining of the back of the eye) is important, because laboratory studies have shown that too much exposure to blue light can damage light-sensitive cells in the retina. This causes changes that resemble those of macular degeneration, which can lead to permanent vision loss. Although more research is needed to determine how much natural and man-made blue light is “too much blue light” for the retina, many eye care providers are concerned that the added blue light exposure from computer screens, smartphones and other digital devices might increase a person’s risk of macular degeneration later in life.
