Blink More, Screen Less: Expert Warns Against Dry Eye from Screen Overuse
— December 22, 2024
ISLAMABAD (AIA) Prolonged screen time can significantly increase the risk of dry eye syndrome (DES), warns Dr Shahid Azeem Mirza, Head of Ophthalmology at Jinnah Medical & Dental College.
“Staring at digital screens reduces our blink rate by 60 to 70 per cent, which disrupts the natural tear flow and can lead to dry, irritated eyes,” Dr Mirza told the media. Left unchecked, the condition may cause discomfort, blurred vision, and even long-term eye damage, he cautioned.
To combat DES, Dr Mirza recommended taking regular breaks from screens and incorporating blinking exercises into daily routines. He suggested setting reminders on digital devices to encourage blinking and reduce symptoms. “Blinking replenishes the tear film, which is essential for maintaining healthy eyes,” he explained.
Dr Mirza also highlighted the risks associated with excessive screen use among children, emphasising that their developing eyes are particularly vulnerable to damage. He urged parents to monitor and limit screen time, encouraging alternative physical and mental activities to protect their children’s eye health.
“By promoting healthy habits and setting boundaries, parents can help reduce the risk of DES and other vision-related problems,” he added.
Another contributing factor to eye strain, Dr Mirza noted, is screen glare, which exacerbates visual discomfort and dryness.
