How to protect your eyes from digital screen?

Before jumping in to How?, let us first see What?

What is blue light? And how it affects your eyes

Digital screens like computer monitor and Smartphone screens emits a blue like light that affects our delicate eyes though we decrease the brightness level to some level. This light is emitted during both day and night times. But since during day times, the glow emitted is countered by daylight, it doesn’t affect our eyes. But during night times, the effect is drastic. You can feel the difference by using the smartphone with and without switching on the tube light in your room.  Melatonin is a hormone associated with night time. But this Bluelight can suppress this melatonin. This is why we wont feel sleepy easily if we keep on staring at the mobile screens.

I know it is impossible to stop using them in night Just because it has its impacts.

Why reducing brightness wont help?

We can’t prevent blue light just by reducing the brightness. Because if we reduce the brightness, it will not just reduce the blue light but also the other components of color (Remember Primary colors Red, Blue and Green?). But we can counter bluelight by filtering it with red like filter through Applications.

Below are the list of applications that can be used to filter the screen.
