What is blue light filter

Blue light filter: On the other end of the visible light spectrum, blue light rays with the shortest wavelengths (and highest energy) are sometimes called blue-violet or violet light. This is why the invisible electromagnetic rays just beyond the visible light spectrum are called ultraviolet (UV) radiation.

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.

Allow distance. Being too close to your screen is also a factor in how your eyes can be negatively affected—they have to work harder to see things that are closer. If possible, keep your monitor or screen about 25 inches away, or about an arm’s length away. Make sure to position the screen so your eye gaze is directed slightly downward. Adjust the brightness. When a screen is much brighter than the surrounding light, eyes have to work harder. If you can, adjust your room lighting and try increasing the contrast on your screen.

Like ultraviolet radiation, visible blue light — the portion of the visible light spectrum with the shortest wavelengths and highest energy — has both benefits and dangers. Here are important things you should know about blue light: Blue light is everywhere. Sunlight is the main source of blue light, and being outdoors during daylight is where most of us get most of our exposure to it. But there are also many man-made, indoor sources of blue light, including fluorescent and LED lighting and flat-screen televisions. Most notably, the display screens of computers, electronic notebooks, smartphones and other digital devices emit significant amounts of blue light.
