Symptoms Symptoms include tired eyes, dryness, headaches, blurred vision and neck or shoulder discomfort. Reduced blinking and uncorrected vision contribute.
Prevention Use regular breaks, blink fully, position the screen slightly below eye level, reduce glare and keep a comfortable viewing distance. The 20-20-20 habit can help remind users to look far away regularly.
Eye examination Persistent symptoms may reflect dry eye, an outdated prescription, focusing problems or another eye condition.
Blue-light glasses Blue-light filters are not proven to prevent eye disease from ordinary screen use. Comfort improvements are more likely to come from breaks, correct glasses and better ergonomics.
