Apps(Android) to Save Your Eyes from Harmful Blue Light

The names of these apps are similar to each other but each of them have something unique about them.

Blue Light Filter – Night Mode, Eye Care

Blue Light Filter is a great app with its best feature being the availability of different modes for different lighting conditions in which you would use your phone like in sunlight, in an artificial lighted environment, in dark, under a candle etc. You can also adjust the intensity of the selected mode or the brightness of the screen according to your need.

You can also save your own custom settings as presets and switch between them with just a single click.

I liked this app very much. But there’s only one thing that bugs me about this particular app, and that is the ads(in free version). You can opt to remove those ads but that will cost you 200 INR.

This app is a no nonsense app which will do just what you want it to do. You can select from some modes like Lamp, Sunset etc. It also has a timer setting using which you can schedule to start/stop the display mode according to your working hours on the phone.

And this app is totally ad free but there’s only one problem with this app. It leaves notification bar while applying it’s filter and hence it seems weird.

Apart from the features like presets(Bedtime Reading is the best pre-saved preset) and timer, Twilight also allows you to start it as soon as you start your phone. Other apps may need to be started once if a person restarts the phone.

You can also schedule when you want a particular light filter to be applied automatically based on the time of sunset/sunrise and you can also specify custom time when you want to start it.

There’s one unique thing about Twilight. It also filters your homescreen wallpaper which I didn’t like much as a feature as the color overlay and the filtered wallpaper makes your it a totally different thing. You can turn it off though.

This is another great app. The USP of this app is the Eyecare Test module. You can test if your eyes are tired and it also has some simple exercises to refresh your eyes and relieve some of your eye strain.

This app doesn’t have saved modes though which is a bummer and it also has a lot of ads. So if ads annoy you very easily, don’t install it at all. Worth a try though.

If you are looking for a similar app for your desktop/laptop, learn how to install F.lux on your Linux and/or Windows machine.

If you think I have missed something out, comment down below for your addition.

Flux: Your Night Work Companion

If you are like me who likes to work at nights and even don’t hesitate to pull all-nighters then F.lux will save your eyes from the strain caused due to long working hours you put on your computer/laptop.

The light coming from the screens of the devices you use every day has a blue light component. This blue light component, having a shorter wavelength, has more energy(as the wavelength of a light is inversely proportional to its energy). The energy of that blue light is strong enough to convert retinal fluid(fluid required by photoreceptors in order to sense light) into a poisonous chemical. This poisonous chemical can not only kill photoreceptor cells but can also kill all kinds of human cells like neurons and heart cells. Overtime, the person may go blind due to Macular Degeneration.

This is something to worry about. Because if you go blind, how would you read my blogs. 😛

But don’t worry much, I’ve got you covered.

The blue light emitting from your computer/laptop screen can be reduced to safe levels by using a simple software named “F.lux” and here’s how you can install it.
