Does this sound familiar? A typical morning starts with checking your phone. Then you go to work and spend eight hours staring at a computer. And then you watch Netflix or scroll social media before bed. Add it all up and optometrist Selina McGee, OD says it’s not uncommon to spend 13 hours or more looking at a screen each day.
While it may not seem like a big deal, studies have shown that your blink rate decreases from 20 blinks a minute down to just seven whenever you focus on a screen. And when you do blink, you rarely blink fully. “This causes eyes to miss out on the much-needed hydration from natural tears, which then leads to eye dryness, burning, irritation, and discomfort,” McGee tells Bustle.
Then there’s the issue of eye strain. “If you have normal vision and don’t need glasses for the distance, your eyes need to change focus to see things up close,” says optometrist Dr. Norman Shedlo, OD. By staring at a screen all day, especially one that’s right in front of your face, Norman says your eyes have to work overtime to stay focused, which can lead to muscle fatigue.
