For today’s young learners, the shift from textbooks to digital screens has altered education. However, the prolonged screen time needed by digital learning has introduced a bunch of eye health challenges that parents and educators are now witnessing closely. Several studies indicate that online learning is linked to several eye issues, including myopia, dry eye disease , and digital eye strain (DES), along with other neglected problems like fatigue, light sensitivity, and trouble with visual focussing. An Indian Journal of Ophthalmology research mentioned that digital eye strain has become prominent among children attending online classes for over two hours daily. In fact, more than 50% of these children reported DES symptoms, like itchy eyes and headaches being the most common.

The rise of myopia
Myopia, also known as nearsightedness, has seen a concerning rise among kids who spend hours on screens every day. When the eyes grow longer than normal, this condition occurs, causing distant objects to appear blurry. Experts worry that without intermediation, myopia rates could continue to increase, with projections depicting that nearly 50% of the world’s population may be affected by 2050. To alleviate the risk, parents and educators can encourage children to take regular screen breaks, ensure good lighting in learning spaces, and let them spend more time outdoors. Also, using devices with adjustable screen brightness and blue-light filters can also help to a certain extent.

The growing concern of dry eye disease
Due to digital learning, dry eye disease in children has also become a common problem. When the eyes do not produce enough tears or the tears evaporate quickly, then this condition occurs. Staring at screens for prolonged hours can cause dry, itchy eyes, and even result in blurred vision. Burnings sensations is one symptom of dry eyes. Inadequate humidity, continuous screen use, and indoor air conditioning can worsen dry eye symptoms. A well-lit space and taking frequent breaks to blink and rest can be helpful. One may also use artificial eye drops but under an expert’s guidance.


Digital eye strain and screen-induced fatigue
Digital eye strain is another common issue among students engaged in prolonged screen-based learning. Bright screens emit blue light which can lead to fatigue. Children then often complain of blurry vision, headache, difficulty in paying attention, and even shoulder and neck ache due to poor posture during screen use.
Taking a 20-second break to look at something 20 feet away every 20 minutes, also known as the 20-20-20 rule, is a simple yet effective strategy. Regulating the brightness and contrast of screens, using blue-light-filtering glasses, and teaching proper seating posture can all ease symptoms of eye strain.

Light sensitivity and photophobia
Some children may also develop sensitivity to light. It’s called photophobia. This can cause discomfort or pain in brightly lit environments or if using screens for a long time. One may experience watering eyes, headaches, and squinting. Solutions to this problem include using anti-glare filters and taking regular breaks.
It is important to balance screen time with activities that promote eye well-being. Regular eye check-ups are must and simple preventive practices should be adopted. Establishing healthy routines can help in the long run, both academically and maintain strong vision as they grow.
