Computer screens cause eye strain mainly due to extended focus on close objects, which stresses the eye muscles. Blue light emission from screens can disturb sleep patterns and cause discomfort. Poor lighting and glare, improper screen settings, and not taking breaks can exacerbate the problem. To reduce eye strain, follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. Adjust screen settings for brightness and contrast, and ensure proper lighting in your workspace.
