 How to Stop Your Eyes from Burning by Nandita Kamalakannan

If you have ever spent three hours aggressively scrolling through your phone or trying to

beat a video game level, you probably know the feeling. You finally look away from your

monitor, and your eyes feel like they are made of sandpaper. Your vision is slightly

blurry, and the room feels too bright.

We usually just blink a few times, rub our eyes, and go right back to the screen. But that

burning sensation actually has a medical name: digital eyestrain.

When you are looking at a screen, a couple of weird biological things happen. First,

your blinking rate drops drastically. Humans normally blink about 15 times a minute,

which keeps our eyes perfectly lubricated. But when we are deeply focused on a digital

display, that number drops to a half or even a third of our normal rate. You are

essentially having a staring contest with a glowing rectangle, and the rectangle always

wins. This lack of blinking causes the tears on the surface of your eye to evaporate,

leading to that dry, gritty feeling.

Second, your eye muscles get exhausted. Your eyes are not designed to focus on a

fixed, close-up object for hours at a time. It is the biological equivalent of holding a

heavy object straight out in front of you—eventually, your muscles are going to cramp

up.

Luckily, eye care professionals have come up with a ridiculously simple hack to fix this

without forcing you to completely abandon your devices. It is called the 20-20-20 rule.

The rule is easy: for every 20 minutes you spend staring at a screen, you need to look

at something that is at least 20 feet away for 20 seconds.

You don't need a tape measure to find something exactly 20 feet away. Just look out a

window at a tree, a building across the street, or focus on the furthest wall in the room.

That 20-second break is the amount of time it takes for the tiny muscles in your eyes to

completely relax and reset. It also breaks your digital trance, reminding your brain to

start blinking at a normal speed again.

So the next time you are halfway through a movie marathon and your eyes start to feel

heavy, do not just ignore it. Look out a window for twenty seconds. Your retinas will

thank you.
