As many as one-third of all urban children in India aged 5-15 years are expected to suffer from myopia by 2030, reveal eye doctors during the ongoing Myopia Awareness Week at Dr Agarwals Eye Hospital in Mumbai.
By 2050, one out of every two children in the country will be myopic, they have predicted based on the ongoing trend. Studies show that in the 20-year period from 1999 to 2019, the incidence of myopia among urban children has tripled in India, from 4.44 percent to 21.15 percent, respectively.
Dr Smit M Bavariya, cataract surgeon, shares her observation on witnessing a steady rise in the number of myopia cases in urban children. "About 120,000 myopic patients under the age of 20 visit Dr Agarwal's Eye Hospital every year across India."

The prevalence of myopia in 5 to 15-year-old urban children increased from 4.4 percent in 1999 to 21.1 percent in 2019. Our predictions, based on the slope of 0.8 percent every year, indicate that the prevalence of myopia among urban children will increase to 31.89 percent in 2030, 40 percent in 2040 and 48.1 percent in 2050. This means that one out of every two children in India will be suffering from myopia in the next 25 years, up from one in four currently.
Dr Smit M Bavariya added: "The patient profile has also been changing over the years. Younger kids are now coming in frequently for an eye checkup and more and more of them are getting diagnosed with myopia. We currently see many cases of moderate myopia in school- going children between the ages of 5 to 17 years. In 2017, our survey of 1,000 children aged between 3-15 in an urban slum area of Mumbai, found that 200 had myopia."
A sedentary lifestyle, prolonged screen usage and reduced outdoor activities are contributing to the rapid rise in myopia cases in children, according to the doctor. He further said that the root causes of this escalating issue are multifaceted. Excessive screen time stimulates the eyes, retina and brain of children, leading to accelerated myopic changes due to rapid eyeball growth. Additionally, a decline in outdoor activities deprives children of essential natural light exposure crucial for healthy eye development.
Dr Smit M Bavariya stressed upon the identifying the symptoms of myopia in children is important for early intervention. Symptoms include blurry vision, difficulty seeing distant objects, eye strain, headaches and fatigue - particularly after prolonged screen use.
Though the condition cannot be cured, it can be helped with glasses or contact lenses. Laser vision correction treatment can also be opted after the age of 19 years. But it is important to have regular eye check-up, encourage children for outdoor activities to balance screen time, and consider interventions like atropine eye drops or myopia control glasses to slow further progression of myopia.
It is important to detect and treat myopia promptly in children as any delay can lead to amblyopia (lazy eye syndrome).
