With most state governments hesitant to reopen schools because of rising Covid-19 infections, e-learning and online classes are set to continue for the foreseeable future. Though prolonged exposure to digital screens is adversely affecting the eye health of children of all age groups, secondary school students (classes IX-XII) are especially vulnerable as the duration of online classes is longer because of board Protecting children’s eyes during online learningexams preparation, and the need to use computers after-school for projects and assignments. Moreover adolescents tend to spend additional time on social media. This has resulted in an increasing number of adolescents complaining of eye strain, fatigue, and headaches.

According to Bengaluru-based ophthalmologist Dr. B.V. Ashalata, eye strain and fatigue can be prevented by following simple digital device usage protocols. “It’s advisable to keep the computer screen at a distance of at least 12 inches or a foot away from the eyes. This is necessary because whenever a digital device is on, electromagnetic radiation is generated, which affects the eyes and body. Exposure to electromagnetic radiation causes eye strain, headaches, giddiness, and hurts concentration,” says Dr. Ashalata

Prolonged on-screen time also causes eye muscle problems such as myopia, hypermetropia, premature presbyopia and computer vision syndrome, which manifests in the form of blurred vision, double vision, red eyes, headaches and eye irritation. “Myopia aka nearsightedness, is a common condition in children who use digital gadgets for long periods of time,” she says.

Dr. Ashalata’s advice to ameliorate eye strain during online classes:

  • Ask your teen to place an elbow on the table and then rest her head on that hand. From this position, lift the elbow and touch the screen; that is now the working distance she should maintain from the terminal.
  • Follow the 20-20-20 to rule out 20-20 vision. Every 20 minutes look away from the screen at objects/sights 20 feet away for 20 seconds.
  • Taking mini-breaks from screen exposure is more beneficial that using protective screens and glasses to reduce eye strain.
  • Encourage children to play outdoor games.
  • Headaches, excessive blinking, eye rubbing, and fatigue are warning signs of vision problems.
  • Dry eyes are also a symptom of poor ocular health. When children stare at a screen, the blinking rate reduces to 5-10 per minute. This can lead to dry eyes. Remind children to blink often.
  • Visit your ophthalmologist at least once a year for a check-up. This has become more important now because of children spending more time on screen.

Try some yoga for the eyes

Palming. Sit cross-legged on the floor or chair spine straight. Rub the palms vigorously and place them over your eyelids without exerting pressure on the eyes. You will feel the warmth and the eyes relax. Lower your hands and repeat the process three times.
