Some tablets and phones come with a feature built in called a blue light shield, or filter. I have one in right now for review from Acer with just that. And it's absolutely magnificent.
It's something I've never even thought about before, despite having heard all the warnings about how blue light can cause some pretty bad eye strain. But regardless of the actual science I can now say I'm 100% converted.
And you should be too. Your eyes will thank you for it.
First, a short bit of blurb from All About Vision:
Because short-wavelength, high energy blue light scatters more easily than other visible light, it is not as easily focused. When you're looking at computer screens and other digital devices that emit significant amounts of blue light, this unfocused visual "noise" reduces contrast and can contribute to digital eye strain.
That's about as much science as I can manage in one go, but the tl;dr is that it can strain your eyes. With that comes discomfort, potentially more than that depending on the individual. It's not good to block all blue light, all the time, but at the right time it can help.
In my own use case, much of my tablet use nowadays is at night. Reading, light browsing, watching Twitch streams, consuming content of all kinds. Even with the brightness turned right the way down, it's not long before my eyes are telling me to stop.
Enter the Acer Predator 8, a tablet crossing my path for review. Right there in the notification shade is a toggle for "Bluelight shield." I figured i'd try it out and instantly my eyes felt better. The colors aren't true anymore, but even that doesn't seem too bad when you get used to it.
In fact, toggling the feature off and on again at night had a noticeable, and instant feeling in my eyes. Without the shield on I could feel my eyes straining at the screen. With it activated I felt much less strain and overall more relaxed. It's led to being able to enjoy some evening content before bed without that horrible feeling in the front of my head.
The difference is instance, and very noticeable
If your phone or tablet has such a feature built in, I definitely recommend giving it a try if you've not done so before. If not, hit the Play Store and try an app such as Twilight to get similar effects and results.
I'm converted 100% now to the point where I've installed software on my PC to do the same thing when it gets late (because you never know when the day will end at Mobile Nations!) I don't have any particular eye complaints, but this simple feature has already left me feeling a lot better while using my mobile tech.
Give it a try and see how you feel after. And if you've got any experiences or apps you think we should know about, do drop them into the comments below.
