You probably don’t think much about blinking. It’s one of those automatic things your body does, like breathing or shivering when you’re cold. But in a world ruled by screens—phones, laptops, tablets, TVs—blinking is under threat. And while it might sound dramatic, not blinking enough can have a bigger impact on your health and wellbeing than you realise.
Let’s start with the basics: the average person blinks between 15 to 20 times a minute. That’s around 1,200 times an hour. But when you’re staring at a screen? That number drops by as much as two-thirds. Suddenly, you’re blinking five times a minute—or less. That might not seem like a huge deal, but your eyes would strongly disagree.
The Dry Truth About Digital Eye Strain
Blinking is how your eyes stay lubricated. Every time your eyelids come down, they spread a thin layer of tears across the surface of your eyes. It’s a cleansing, protective sweep. So when you’re deep in a spreadsheet or scrolling through social media, that reduced blink rate means your eyes aren’t getting the moisture they need. Cue the classic symptoms: dryness, itching, redness, blurred vision, and that burning, sandy feeling behind your eyelids.
This is what’s often labelled as digital eye strain (or computer vision syndrome, if you want the formal term). And it’s not just irritating—it can actually impact your productivity and make screen time more draining than it needs to be. People often mistake it for tiredness or even headaches from poor posture, when the culprit is, quite literally, right in front of their eyes.
The Long-Term Effects of Forgetting to Blink
In the short term, your eyes get tired and uncomfortable. But over time, things can start to escalate. Chronic dry eye is on the rise, particularly in people who spend their working days at computers and their evenings watching Netflix on a tablet. When your tear film—the thin layer of liquid that protects your eyes—starts to deteriorate from lack of blinking, it can lead to inflammation and damage to the surface of the eye.
There’s also evidence that under-lubricated eyes can struggle to focus properly, making reading and detailed tasks harder. And if you wear glasses, you might find yourself swapping prescriptions more often than you’d like—not always because your vision has changed, but because your eyes are constantly strained.
That’s where lens coatings like anti-reflective filters and blue light blockers can help. They don’t replace blinking, but they do reduce the glare and visual noise that make your eyes work harder. If you wear prescription glasses, it’s worth checking if your lenses have these built in—or if you can add them on. A good pair of glasses can act like a shield between your eyes and the digital chaos.
Screen-Zombie Symptoms: It’s Not Just About the Eyes
While dry eyes are the headline issue here, they’re not the only problem. Not blinking enough tends to come with a host of knock-on effects.
People often tense their facial muscles when focusing on screens, particularly the brow and jaw. Add in a lack of natural eye movement, and it’s easy to end up with screen headaches, facial tension, or that end-of-day feeling where your whole head feels heavy.
Not blinking also means you’re not getting those tiny, subconscious breaks your brain needs. Blinking helps momentarily disengage your attention, resetting your focus. Without it, your concentration dips and mental fatigue sets in faster. This is partly why it’s so easy to feel mentally wiped out after a long day of seemingly ‘easy’ work on a screen.
Breaking the Blinkless Cycle
The solution isn’t as simple as “just blink more”. You can’t force it. It has to become part of how you use screens more mindfully. That’s where small but consistent habits come in.
-
- Follow the 20-20-20 rule: Every 20 minutes, look at something 20 feet away for 20 seconds. It sounds basic, but it helps relax your eye muscles and gives your blink reflex a chance to kick back in.
- Position your screen properly: Ideally, your screen should be slightly below eye level, so you’re not staring straight ahead. This encourages a more natural, downward gaze—and more frequent blinking.
- Keep the air around you in check: Central heating and air con both dry out the air and your eyes. Use a humidifier if needed, and make sure your screen setup isn’t right under a vent.
- Use eye drops if you need them: Artificial tears can help keep your eyes comfortable if blinking alone isn’t cutting it.
- Invest in eyewear that supports your screen time: If you’re wearing glasses daily—and especially if you’re working long hours on a screen—make sure your lenses are working as hard as you are. Anti-glare coatings and light-responsive lenses are worth considering. You can browse prescription glasses designed specifically with digital use in mind.
Blinking Back to Life
Being glued to a screen is something most of us can’t avoid. It’s where we work, relax, talk to friends, shop, and even exercise. But becoming a screen-zombie—blinkless, brain-fogged, and eye-strained—doesn’t have to be inevitable.
The key is to treat your eyes as the active, living organs they are. Give them breaks. Let them move. Protect them with the right lenses if you need them. And above all, let them blink. It might seem small, but it’s one of the simplest, most natural ways to protect your vision in a digital world.
You don’t need to ditch your screen—you just need to look at it a bit more kindly. And let your eyelids do their thing.
