Do your eyes feel like they’ve been running laps around a track field after a long day of staring at screens? You’re not alone. This is what life is like nowadays. Even though technology has made so much possible, it’s also brought an onslaught of trouble for eyesight, and it’s important to recognize why this is happening and how to protect your vision. It’s called digital eye strain, and it does a number on your eyes, as your Pittsburgh, PA optometrist can explain.

Reduced Blinking and Dryness

When looking at screens, people tend to blink far less than usual—sometimes as little as half their normal rate. Blinking is essential for keeping the eyes moist and refreshed. When you don’t blink enough, your eyes dry out, leading to irritation, redness, and that heavy, tired feeling.

Constant Focusing Effort

Reading on a screen requires your eyes to constantly adjust focus, especially when switching between different text sizes, images, or windows. Unlike looking at a physical book, digital content often includes glare, small fonts, and moving elements that demand extra effort. Over time, this strain can make your eye muscles feel fatigued.

Exposure to Blue Light

All screens emit blue light, which has been linked to increased eye strain and disrupted sleep patterns. Blue light is invisible to the naked eye, but trust us, it’s there. While blue light itself isn’t harmful in small doses, prolonged exposure can contribute to discomfort and make it harder for your eyes to relax. It may also interfere with melatonin production, making it more difficult to wind down at night.

If your eyes are chronically tired, with or without screen time, you should definitely get an eye exam in Pittsburgh, PA. Contact Lappen Eye Care today to book your appointment.
