The government is set to change a four-decade-old definition of blindness to bring it in line with the WHO criteria and ensure the Indian data on blindness meets the global estimates. The change in definition will bring down the number of blind persons by 4 million in India.

The World Health Organisation (WHO) defines blindness as visual sharpness of less than 3/60, or a corresponding visual field loss to less than 10 degrees in the better eye, even with the best possible spectacle correction. The National Programme for Control of Blindness (NPCB) in India, on the other hand, defines blindness as vision of 6/60 or less and a visual field loss of 20 degrees or less in the better eye, after spectacle correction.

This means a person unable to count fingers from a distance of six metres is categorised as “blind” in India, against the WHO’s stipulation of three metres.
