Ophthalmologists say that that myopia (shortsightedness) is on the rise, especially among school going children. They say that glasses are more effecting to eye ball than doing good. In past children didn’t have mobile phones and other gadgets they used to play outdoor games.
Ophthalmic scientist Dr Srinivas Marmamula, who has accomplished an extensive study on myopia said “In Mahbubnagar it was quite low but in Delhi the prevalence was high. We looked at all the factors that could be driving this difference and found ‘near-eye work’ to be the factor that made a big difference”.
To give the eyeball more exercise doctors often prescribe an hour of outdoor activity each day. Wearing eyeglasses may not exactly help in correcting myopia and in turn could be causing problems added scientists. Dr Shrikanth Bharadwaj, associate director of Optometry at LV Prasad Eye Institute, explained that “We always thought that the central part of the eye matters in myopia correction but it has been increasingly shown that even the peripheral parts of the eye matter. But our eyeglasses don’t help the periphery so they may actually be doing a lot of disservice”. Though Indians are not genetically predisposed, factors such as increased use of mobile phones, tablets and computers could be trigger factors he thinks.
Dr Srinivas said “There is no direct measure. But definitely, of late, there are more children wearing glasses.” In South East Asian countries 70 per cent prevalence is high for Myopia.
