Do you experience digital eye strain? Symptoms include tired, dry eyes and occasional headaches after a long day staring at phones or computer screens. Unfortunately, the effects of excessive screen use go far beyond temporary discomfort. At St. Michael’s Eye & Laser Institute, our doctors help patients in St. Petersburg and Clearwater, FL protect their vision by identifying and managing the broader impact of screen time on long-term eye health.
More Than Just Fatigue
Digital eye strain, also known as computer vision syndrome, is one of the most immediate effects of extended screen use. It’s caused by reduced blinking, poor lighting, and glare from digital devices. While symptoms like dryness, blurred vision, and eye fatigue are common, they often resolve with breaks and better screen habits.
However, consistent overuse of digital screens may contribute to more lasting eye concerns:
Increased Risk of Myopia
Studies show that excessive screen time, especially in children, may be linked to the development or worsening of nearsightedness (myopia). Close-up focus for long periods without outdoor breaks can affect how a child’s eyes grow. The earlier myopia develops, the greater the long-term risks for serious eye conditions like glaucoma or retinal detachment later in life.
Disruption of Sleep Patterns
Screen use in the evening affects more than just your eyes. Blue light emitted from phones, tablets, and laptops can interfere with the body’s production of melatonin, the hormone responsible for sleep. Poor sleep quality doesn’t directly damage your eyes, but chronic sleep deprivation can contribute to dry eyes and worsen existing eye conditions.
Impact on Tear Production and Dry Eye
Spending hours on digital devices reduces your blink rate, which means less natural lubrication for your eyes. Over time, this can lead to chronic dry eye syndrome. This condition causes discomfort, burning, and sensitivity to light, and it can increase your risk of corneal damage if not properly managed.
How to Protect Your Eyes
To reduce the impact of screen time on your eye health:
- Follow the 20-20-20 rule: Every 20 minutes, look at something 20 feet away for at least 20 seconds
- Adjust screen brightness and contrast for comfort
- Use artificial tears if you experience dryness
- Encourage outdoor time for children and take regular breaks from close-up tasks
