Is Excessive Screen Time Bad for My Eyes?

In today’s digital age, it is common to spend hours staring at screens—whether that’s for work, school, or entertainment. But is all this screen time harming your eyes? The short answer: it can be. 

Excessive screen use can lead to a condition known as digital eye strain or computer vision syndrome. Symptoms often include dry eyes, blurry vision, headaches, and even neck and shoulder pain. These issues can occur because we tend to blink less when focusing on screens, reducing tear production and straining the muscles that help the eyes focus. 

Blue light emitted by screens may also disrupt sleep patterns by interfering with melatonin production, especially when devices are used late at night. While research is ongoing about the long-term impact of blue light on eye health, many eye care professionals recommend minimizing exposure when possible. 

To protect your eyes, you can follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. Also, consider adjusting your screen brightness, reducing glare, and keeping devices at an arm’s length and just below eye level. 

Importantly, regular comprehensive eye exams play a key role in maintaining healthy vision. At Prestera Eye Medical Group, Dr. Tory Prestera and Dr. Howard Guan can detect early signs of digital eye strain and other vision problems, many of which may go unnoticed in the early stages. They can also recommend tailored strategies or specialized lenses to help reduce screen-related discomfort. 

If you are experiencing symptoms of digital eye strain or simply want to stay proactive about your eye health, don’t wait. Schedule an appointment and comprehensive exam with one of our eye doctors and give your eyes the care they deserve. A few simple changes—and regular checkups—can make a big difference in how your eyes feel day to day.
