Find yourself squinting while staring at your phone or computer? You’re far from alone. A recent report estimated that half the world will be nearsighted by 2050. (Good thing glasses are trendy!)

That number is a huge increase from 2000, when just a quarter of the world had myopia (the medical term for nearsightedness). However the optometrists we spoke with didn’t find the estimate surprising. “We see people with mild myopia worsening every year,” says Eric Perez, an optometrist. “We see patients with myopia that do not have a family history of it.”

Two culprits are likely to blame:

1. Increased Screen Time

Eye doctors use the term “near work,” but mostly they’re referring to the screens you look at (like right now!). As we spend more time looking at computers and smartphones that are just a few feet—and sometimes only inches—away, we don’t give our eyes a chance to look into the distance. (So now you know why you have so much trouble reading road signs.)

2. Decreased Time Outdoors

When you’re outdoors, you tend to look at more objects in the distance, exercising that part of your vision, Perez says. There’s also research that shows natural sunlight tr…
