Half the world’s population (nearly 5 billion) will be short-sighted (myopic) by 2050, with up to one-fifth of them (1 billion) at a significantly increased risk of blindness if current trends continue, says a study published in the journal Ophthalmology.
The number with vision loss from high myopia is expected to increase seven-fold from 2000 to 2050, with myopia to become a leading cause of permanent blindness worldwide.
The rapid increase in the prevalence of myopia globally is attributed to, “environmental factors (nurture), principally lifestyle changes resulting from a combination of decreased time outdoors and increased near work activities, among other factors,” say the authors from Brien Holden Vision Institute, University of New South Wales Australia and Singapore Eye Research Institute.
