Dr. Shahid Azeem Mirza, Head of the Ophthalmology Department at Jinnah Medical & Dental College, stated that the blink rate significantly decreases by 60 to 70 per cent when individuals focus on digital screens.
This reduction in blinking heightens the likelihood of developing dry eye syndrome (DES).
In a media discussion, he recommended taking regular breaks from screen usage to mitigate the risk of DES. He explained that as screen time increases, individuals tend to blink less frequently, which disrupts the natural flow of tears and results in dry and irritated eyes.
If not addressed, this condition can lead to discomfort, blurred vision, and potential long-term damage to the eyes. To alleviate DES, Dr. Mirza proposed integrating a straightforward blinking exercise into one’s daily routine.
He advised setting reminders on digital devices to appear every few minutes, prompting users to blink and alleviate symptoms of DES. He highlighted the importance of blinking in maintaining eye health by replenishing the tear film.
Additionally, he expressed concern regarding excessive screen time among children, warning of the potential for lasting harm to their eye health. He pointed out that children’s eyes are still in development, making them more vulnerable to the adverse effects of extended screen exposure.
The ophthalmologist called on parents to supervise and limit their children’s screen time, advocating for alternative activities that foster both physical and mental health.
He concluded that by establishing boundaries and encouraging healthy habits, parents can safeguard their children’s eye health and diminish the risk of developing dry eye syndrome and other vision-related issues.
