How to install tempered glass screen protector: 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.

It’s no surprise that nearsightedness is the number one eye issue in the world right now. In 2016–2017, we spent an average of 10.4 hours on our devices a day. It’s why many if not most of us deal with eyes that feel “shot” — dry, itchy, sometimes accompanied by a headache, what’s occasionally called “computer vision syndrome”. Different age levels require different levels of protection. Children under the age of 14 who use tablets and phones with high energy light are at special risk. Until 14, their corneas aren’t fully developed, and lack the protection of adult eyes — especially if they’re constantly in front of a device. Increased and prolonged exposure to HEV is a contributing factor to increased diagnoses of nearsightedness among children.
UV rays have higher energy than visible light rays, which makes them capable of producing changes in the skin that create a suntan. In fact, the bulbs in tanning booths emit a controlled amount of UV radiation specifically for this reason. See more details at Perfectsight screen protectors.
