Digital screen use linked to growing fatigue and dry‑eye symptoms

Extended multitasking, constant decision‑making and the pressure to be constantly available can deplete mental energy. Habitual multitasking forces the brain to switch tasks, increasing fatigue, reducing concentration and raising stress. Over‑decision making, known as “decision fatigue,” and the need to always say “yes” further drain psychological resources. Simple strategies such as focusing on one task at a time, taking short breaks and setting clear personal limits can help restore mental stamina.

Prolonged viewing of screens also strains the eyes. The reduced blink rate while looking at digital devices accelerates tear evaporation, leading to chronic dry‑eye disease. Symptoms include burning, gritty sensations, intermittent blurred vision and quick eye fatigue. Experts advise the 20‑20‑20 rule – every 20 minutes, look at a point 6 m away for 20 seconds – along with regular breaks, humidified environments and a diet rich in omega‑3 fatty acids. Women after menopause and individuals with autoimmune conditions are at higher risk. Early ophthalmologic assessment is recommended for persistent cases.
