Digital Eye Strain (DES) refers to symptoms such as eye fatigue, headaches, blurred vision, and dry eyes because of prolonged digital screen focus.

It is more common in urban children due to excessive use of digital devices for learning and entertainment. The incidence has increased almost 3x, especially after the Covid pandemic. Here are some ways to prevent digital eye strain:

• Teach her the 20-20-20 rule. Look 20 feet away every 20 minutes for 20 seconds.

• Encourage regular blinking and hydration.

• Use anti-glare screens / glasses.

• Ensure digital devices are at least 18-24 inches away from her face.

• Schedule tech-free breaks. Alternate every 45 minutes of screen learning with offline worksheets, reading, or physical activity.

• Ensure she engages in at least 60-120 minutes of daily outdoor activity.

• Teach her simple eye exercises to alleviate strain.

• Consult with your paediatrician or ophthalmologist to check if she needs to use tear drops.
