Excessive screen time can lead to various visual discomforts like headaches, dry eyes, and blurry vision, highlights experts.

Dr. Wisner from Wills Eye Hospital underlines the impact of reduced blinking and tired eye muscles on these symptoms.

Exploring the Causes of Blurry Vision

According to Amy Watts, director of vision rehabilitation at Massachusetts Eye and Ear hospital, prolonged screen time can lead to blurry vision due to reduced blinking and fatigue in the eye muscles. Blinking less frequently hinders the eye's natural lubrication process, akin to raindrops accumulating on a windshield, obstructing clear vision.

Additionally, sustained focus strains eye muscles, impacting their ability to function optimally, thereby resulting in vision deterioration throughout the day.

These factors contribute to temporary blurred vision and various symptoms such as headaches, redness, itchiness, fatigue, and general eye discomfort.

Managing Digital Eye Strain

Amy Watts suggests taking frequent visual breaks to prevent eye strain. While the 20/20/20 rule is popular, recent research indicates longer breaks may be more effective. Additionally, using preservative-free eye drops and ensuring proper lighting and clean screens can alleviate symptoms.

Blue-Light Glasses and Sleep Hygiene

The use of blue-light glasses is inconclusive, notes Steven Reed from the American Optometric Association. Limiting screen time before bed is vital as it can impact sleep quality. Dr. Wisner emphasizes the importance of good sleep in preventing chronic fatigue and eye strain.

Addressing Concerns about Digital Eye Strain

While digital eye strain is typically harmless, persistent symptoms may indicate underlying vision issues. It is advisable to consult a professional if problems persist.

For children experiencing blurry vision or eye discomfort from screen use, prompt evaluation is essential. Screen exposure during critical developmental stages may contribute to vision issues like myopia, underscoring the importance of timely medical assessment for young individuals experiencing eye strain symptoms.
