What is blue light??

Blue light us the shortest wavelength of visual spectrum of light. We see it as the deep blue.Blue wavelengths—which are beneficial during daylight hours because they boost attention, reaction times, and mood—seem to be the most disruptive at night. And the proliferation of electronics with screens, as well as energy-efficient lighting, is increasing our exposure to blue wavelengths, especially after sundown.

Source of blue light

Sunlight is the main source of blue light, and being outdoors during daylight is where most of us get maximum exposure to blue light. 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.

The amount of HEV light these devices emit is only a fraction of that emitted by the sun. But the amount of time people spend using these devices and the proximity of these screens to the user's eyes, is a cause of concern for many eye doctors and other health care professionals.

How blue light affect our eyes ??

▪︎The eye is not very good at blocking blue light.

▪︎Blue light exposure may increase the risk of macular degeneration.

▪︎Blue light contributes to digital eye strain.

So,we have to use blue light filter to stop the bad effects of blue light in our eyes.

What is blue light filter and how it is invented??

The University of Manchester published a study (via the Guardian) that found blue light filters may actually trick our brains into thinking it’s daytime, exactly the thing they were designed to avoid.

Those blue light filters, like the Pixel’s “Night Light,” were designed to reduce a protein in your eye called melanopsin. That protein responds to the intensity of light, especially when that light is of a shorter wavelength, i.e. blue lights. When the screen is tinted yellow, the blue portion of RGB lights is lessened considerably.

The study found that warm, yellow light tricks your brain into thinking that it’s actually daytime. The warmer colors tell your body clock that it’s sunrise or sunset, in either case telling your body that it’s not quite time to go to sleep yet.
