Tempered glass screen protector install tips: 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.

Your home: “Smart” appliances like refrigerators often boast a touchscreen with bright blue display. Consider adding a small “drape” or other cover to put over appliance screens, so they doesn’t blast you into insomnia, when you go into the kitchen for a late night glass of water. Appliances with LED-based bulbs are another common culprit — a topic I’ll cover in my next post. Your laptop and appliances: Use Flux at night to slowly decrease your computer’s blue glow as the sun sets. Buy a glare-reducing protective screen cover. Don’t buy electronics with lots of blue light — of if you do, cover the bulbs. Use blue-light protective glasses at night if you can’t avoid using your devices, or can’t entirely block out blue light in your environment.
Generally, scientists say the visible light spectrum comprises electromagnetic radiation with wavelengths ranging from 380 nanometers (nm) on the blue end of the spectrum to about 700 nm on the red end. (By the way, a nanometer is one billionth of a meter — that’s 0.000000001 meter!) Blue light generally is defined as visible light ranging from 380 to 500 nm. Blue light sometimes is further broken down into blue-violet light (roughly 380 to 450 nm) and blue-turquoise light (roughly 450 to 500 nm).
