Not a lot of people know but it’s a good idea to enable blue light filter on your phone. But the question in the mind pops up. Why? And what is ‘Blue Light’?
Harvard Medical school has published the study in recent years which shows that the blue light emitted from the gadgets are responsible for poor sleep at night. And this poor sleep is responsible for flawed body cycle.
We are acquainted with the fact that blue light has a short wavelength. This brings attention to our body cycle during daytime (from sun’s wavelength and energy). But when we use the gadgets during the night, the artificial blue light emittance impacts the biological clock, making our sleep suffer.
And who doesn’t wish a good sleep? It is definitely an utmost important thing to keep the body cycle running efficiently.
What is the role of the Blue light filter?
A smart blue light filter stays mostly unfunctional during the day hours and doesn’t show any change on your phone screen. As the sunset takes place, the screen color changes with red and yellow hues very gradually that you may not even notice.
This color change helps reduce the negative effects of blue light at night time and you will begin to notice less strain on your eyes, with time. Even with the diagrammatic representation above, you will get an idea of different wavelengths that blue and red lights possess.
What to do now?
Apart from in-built modes in the phone that change the color pattern, some blue light filter apps can help keep the eyes calm and maintain circadian rhythm in sync.
