Millions of young children are growing up short-sighted every year because of myopia. The World Health Organization (WHO) estimates that there were nearly two billion people with myopia in 2010 — a quarter of the human population. By 2030, they project myopia prevalence to reach 3.3 billion people. While East Asia and the Pacific have been reporting some of the highest numbers for a decade now, current estimates out of India do not yet reflect this trend. It may mean we have time to act and save the sight of our children.
‘Near-work’ is on the rise
Myopia is commonly found in children. As they grow and their bodies change, the length of the eyeball and its power to refract light do not always align, leading to vision that is blurry. A pair of spectacles is enough to correct this mismatch. However, spectacles address the symptom and not the cause (eyeball length), so myopia can progress all through childhood. Progressive myopia, after a point, leads to ‘high’ myopia, increasing the risk of retinal detachment, glaucoma or macular degeneration that can cause permanent vision loss.
