Screen Overuse Triggers Rising Eye Strain in Colombia and Cognitive Fatigue in Argentina

Doctors in Colombia report a growing number of patients suffering from eye strain and visual fatigue linked to prolonged exposure to digital screens. Symptoms include dry eyes, blurred vision, headaches and difficulty focusing at distance. Health professionals recommend regular breaks, proper screen positioning, reduced brightness and the use of blue‑light filtering lenses to mitigate damage.

Research from the University of Valencia and the Austral University Hospital in Argentina shows that reading on paper improves comprehension and reduces mental fatigue compared with digital devices. The tactile experience, lack of notifications and avoidance of blue light help the brain build stronger memory maps and maintain focus. Experts advise balancing screen use with paper reading for tasks that require deep concentration and retention.
