Expert tips to prevent and treat eye strain

Taking a break from activities causing strain or using artificial tear drops can help, he says. But if you deal with dryness every day, wake up with mucus in your eyes or notice that symptoms don’t improve with rest, talk to an eye doctor. They can check for conditions such as chronic dry eye that may require treatment with prescription medications.

Eye strain also happens when the ciliary muscle, which helps the lens in our eye to focus, becomes tired, Deobhakta says. “We would never question our feet requiring a break after a marathon,” he adds. When staring at something for a long time, Deobhakta says, “we’ve now decided to run marathons with our eyes”.

As the ciliary muscle contracts, it naturally changes the shape of the eye’s lens, Patel says. But as we age, the lens hardens and doesn’t bend as easily, making it difficult to see clearly close up. This condition, presbyopia, is the reason people in their 40s and older are more likely to need reading glasses, he says, though it’s possible to fatigue the ciliary muscle and experience eye strain at any age.

Your eyes may also ache if you’re using glasses with the wrong prescription, or if you don’t wear glasses when you need them, experts say.

“It would be like wearing the wrong shoe and your foot has grown,” Deobhakta says. So if you feel strained when wearing your glasses or contact lenses, or if it’s been more than a year since your last eye exam, get a checkup from your eye doctor.

So, what can I do about it?

Chat with an eye doctor if you notice new symptoms, experts say. A provider can identify underlying conditions or recommend medications and prescription lenses.

And if you’re simply worried about eye strain, experts have tips to minimise it on your own.

Follow the 20-20-20 rule. If you plan to stare at a screen or read a book for a while, take a break every 20 minutes by looking at something at least 20 feet (about six metres) away. Do that for 20 seconds or longer. (Some research suggests 20 seconds isn’t long enough.)

Lubricate your eyes. If your eyes feel dry, consider single-use, artificial tears that don’t contain preservatives, which may cause irritation, Moy says. Check the ingredients label and opt for artificial tears that have phrases like “preservative-free” on the packaging.

Remember to blink. Thinking about blinking may feel silly, Moy says, but it’s a great way to prevent your eyes from drying out and feeling uncomfortable. Consider placing a note with a reminder next to your computer or the book you’re reading, experts say.

Use a warm compress. Run a washcloth under warm water and gently place it over your eyelids for about 10 minutes once or twice a day, experts say. The compress stimulates the glands that release oil, preventing tears from evaporating too quickly, Patel says. But eyelids are thin and sensitive – so, to prevent burns, avoid pushing the compress onto your eyes, Moy says.

Sitting still with a cloth over your eyes may feel like a big ask when you’re busy, she says. But you can use the time to relax.

“Do some deep breathing,” Moy adds. “Have a little spa day.”
