Global blindness set to ‘triple by 2050’.




 

More than 200 million people are living with moderate to severe vision impairment.

Researchers suggest that the number of blind people across the world is set to triple within the next four decades.

They predict that cases will rise from 36 million to 115 million by 2050, if treatment is not improved by better funding.Some of the highest rates of blindness and vision impairment are in South Asia and sub-Saharan Africa.

Because the global population is growing and more people are living well into old age, researchers predict the number of people with sight problems will soar in the coming decades.
