Early onset of myopia to prolong even in adulthood

 Myopia is the most common disorder in childhood, the prevalence has reportedly increased in rural India from 4.6% to 6.8%,compared to a change from 7.9% to 8.9% in urban India during the same period.The risk of developing high myopia is relatively high among children with myopia onset at a young age, while each year of delay in the age of onset substantially reduces the chance of developing high myopia in adulthood.

According to recent research published in JAMA ophthalmology. The development of high myopia carries risks of irreversible blinding complications including glaucoma, retinal detachment, and myopic maculopathy.

The World Health Organization defines myopia as a condition in which the spherical equivalent objective refractive error is ≤ –0.50 diopter (–0.50 D) in either eye. However, in this study, researchers classified high myopia as the spherical equivalent of −6.00 diopters or worse determined by cycloplegic refractions.
