What is blue light? Sunlight contains red, orange, yellow, green and blue light rays and many shades of each of these colors, depending on the energy and wavelength of the individual rays (also called electromagnetic radiation). Combined, this spectrum of colored light rays creates what we call “white light” or sunlight.

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.
Reduce glare. Glass screens can produce glare that can aggravate the eye. If you don’t have control over the lighting in your environment, try using a matte screen filter. Follow the 20-20-20 Rule. Every 20 minutes, give your eyes a break by looking at an object 20 feet away for 20 seconds. This allows your eyes to relax. Limit devices before bed. Research shows that the blue light from your phone and other screens may affect the body’s natural wake and sleep cycle. During the day, blue light wakes us up and stimulates us. It does the same thing at night, which makes it harder to get to sleep. Limit screen time one to two hours before bedtime. Use nighttime settings on devices and computers that minimize blue light exposure.
The eye is not very good at blocking blue light. Anterior structures of the adult human eye (the cornea and lens) are very effective at blocking UV rays from reaching the light-sensitive retina at the back of the eyeball. In fact, less than one percent of UV radiation from the sun reaches the retina, even if you aren’t wearing sunglasses. (Keep in mind, though, that sunglasses that block 100 percent of UV are essential to protect these and other parts of the eye from damage that could lead to cataracts, snow blindness, a pinguecula and/or pterygium, and even cancer.) On the other hand, virtually all visible blue light passes through the cornea and lens and reaches the retina. See extra info on this site.
