Blue blocking readers are eye glasses with lens that have the ability to block out most of the blue light from computer screens and other devices with LED lights, against affecting the eyes of those using them. These glasses are particularly helpful to people who watch their televisions late at night or use their computers, tablets and smart phones just before bedtime, as using these readers can help improve how they sleep.
It’s known that the full range of visible light is red, orange, yellow, green, blue, indigo, and violet. However, the new screen-lighting technology of computers and other such devices uses LED light, which gives off a large amount of blue light. And blue light can be a problem in terms of getting a good night’s sleep. This is because blue light plays havoc with the levels of the body’s melatonin, the hormone which makes a person sleepy. Essentially, the blue light lessens the effect of melatonin and makes it difficult to sleep after hours in front of LED screens.
Blue light blocking readers are specially tinted to block the blue light from reaching your eyes and therefore lessens the interference with the body’s melatonin levels. If you use any of these devices for long hours, especially at night just before bedtime, it might be a good idea to check out the advantages of getting a pair of blue light blocking glasses.
While it’s not recommended to substitute blue light readers for proper care and rest of your eyes, these readers can help stop the effects of sleepless nights after prolonged exposure to computer and other LED light devices.
