Why Should I Activate Blue Light Filter On My Devices?

Blue Light Filter on Android or Night Mode is a feature in smartphones that lowers the blue light emitted from mobile devices and keeps our eyes free from strain and stress. This blue light that brightens up the screen of our mobile devices and gives up the best picture quality has a wavelength similar to the Sun at noontime. We can’t look at the Sun with our naked eyes but tend to spend at least 4 hours on our mobile devices every day. This is clearly damaging our eyes and one of the most common reasons for frequent headaches.

I am not discouraging anyone from using your precious mobile phones but suggesting a new way to look at them. To prevent damage to our eyes and decrease stress from our brain, it is of the utmost importance that everyone enables night mode on their mobile phones, especially while indoors or after sunset. If your device manufacturer has not included this feature in your device, you can install certain apps to reduce our eyes’ strain.
