Blue light is part of the visible light spectrum. The visible spectrum contains blue, orange, green, yellow, and red light rays. Red, yellow, and green light rays have long wavelengths
The screens of digital devices (including Smart-Phones) and personal computers emit short-wave blue light.
Health problems: According to the International Agency for Research on Cancer (IARC)
-Blue light rays can cause cancer, retinal damage, melatonin disruption, AMD, etc.
Also, long-term exposure to blue light can permanently damage your eyes.
-Melatonin is the hormone responsible for regulating the sleep/wake cycles in the brain. Not surprising, blue light directly inhibits our body’s melatonin flow, hurting our ability to fall asleep, in addition to negatively impacting the quality of the sleep we get.
More time in front of screens = more blue light = more headaches & fatigue = lower productivity
Further more, blue light can contribute to blurred vision, sleep loss, fatigue, and dry eyes. These are symptoms of digital eye strain, or computer vision syndrome (CVS). CVS can trigger neck and shoulder strain.
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.
Digital health advocates recommend that mobile users should refrain from using their digital devices over a long period.
It’s hard for some people to reduce the amount of time of cellphone usage.
That’s why screen filters, computer glasses, and filter applications were created. They’re designed to shield your eyes from the blue light.

Blue Light Filter shift the colour tone of smartphones. The harmful Blue light is converted to orange, red, or yellow.
They also reduce screen brightness and protect your retina from blue light penetration.
In Short: The Blue light filter decreases the amount of blue light displayed on the screen of the device.
Blue Light Filter is available From Android OS Version 7.0 (Nougat) in Samsung Galaxy Phones.

At the end of the day (literally), it’s probably just better to stop using your phone instead of using this. You’ll sleep better - by Ben Schoon.
