Effect of Digital Screens on Eye

Digital screens can cause a range of eye-related issues, often referred to as "digital eye strain" or "computer vision syndrome." Common symptoms include:

Dry Eyes: Staring at screens reduces blink rates, leading to dryness and irritation.

Eye Fatigue: Prolonged screen time can cause discomfort and tiredness in the eyes.

Blurred Vision: Focusing on screens for long periods can lead to temporary blurriness.

Headaches: Straining to see or focusing too long can trigger headaches.

Disruption of Sleep: Blue light emitted by screens can interfere with melatonin production, affecting sleep quality.

To mitigate these effects, it’s recommended to take regular breaks (like the 20-20-20 rule), adjust screen brightness, and maintain proper distance and posture while using digital devices.
