Have you ever been using your computer at 11 pm, feeling like your eyes are burning? Yes, I have been there multiple times. How about using your phone before going to bed, but later you can’t sleep? Again, I feel you!

Those symptoms happen when you spend hours staring at a bright screen, such as the ones from your computer or phone. Also, if this pattern repeats, then you are mostly suffering from eye fatigue. An eye strain that can represent retina damage, sleep disorder, depression and more.

You may think that the obvious solution is to lower the brightness of your screen. Well, it seems really clever, but that’s not the root cause of the problem. What causes you that eye strain is in fact caused by the color temperature of the light. Our eyes are sensitive to blue light because the brain uses the amount of this light to know what time of the day is, thus adjusting sleep cycles.

To resume, if you use a bright screen at night, your brain thinks it’s 2pm when it really is 10 pm. That’s why you have a hard time sleeping, and why you need to more effort to use your eyes to see what you have on your screen.

But you still need to use your computer at night right? You need to study for a test, make a video call to a loved one, or just simply read something before sleeping. So, the question is, what you can do?

Luckily for you, this has been already resolved by some cool apps and integrations. They extract that blue light that hurt your eyes, making you feel better even when you use your tech at night.

1. For computers, use f.lux.

Ever notice how people texting at night have that eerie blue glow? That’s the first question you receive at the f.lux page. This great and FREE app is available for Windows, Mac, and Linux. You just download it, install it, and you are good to go!

When you open the app, it will ask for your location, so it can adjust to your local time to make adjustments. When sunset approaches, the app will gradually warm the colors of your screen, decreasing the blue light levels, reaching a point where it no longer hurts you.

Although it’s easy to use, the app is packed with a lot of features, just in case you need to go further in tweaking the levels of light, or if you want more automation. For the average user, after the location is set up all is finished.

Rest Your Eyes

2. For iOS users, just activate Night Shift mode.

Since iOS 9.3, iPhone and iPad users can warm automatically the screen light, just as f.lux does, without installing an app. The feature is called Night Shift, and you can activate it going to Settings, Display & Brightness. There, you can set to adjust it automatically with sunset times, or put your desired ones.

In iOS 10, you can just swipe down-up and activate it on the control center.

3. For Android, install Twilight.

In the same way as f.lux and Night Shift, this app makes your screen adapt to the time of the day. It filters the blue light to help your eyes rest.

Warm Your Android Screen

if you use a bright screen at night, your brain thinks it’s 2pm when it really is 10 pm.

The benefits you will get after warming your screen are:

  • Better sleep quality.
  • Rest for your eyes, lowering or disappearing eye strain.
  • Happier mornings, since your sleep is better.
  • Improve your reading and focus at night.

From now on, I encourage you to filter blue light in your devices, so you can stop trying to be a vampire every day. You can improve your life with a few steps, for free!

    Since High-school i’m a night person, I love reading and at night I can focus better (since most of the people are sleeping and no one bothers you), and it’s a fact that when you study at night you understand better (if your not half asleep while you try to study), for that I developed eye fatigue years ago and now have myopia (a disfunction where the light enter you eye and the rays converge behind the retina); now with these cool apps I can improve the use of my laptop at night when i’m studying and not aggravate my problem. Thanks a Lot Gregory!!
