Number of blind people to TRIPLE by 2050 due to ageing population – Cambridge News

Cases of blindness could treble by 2050, scientists believe.

New research from Anglia Ruskin University suggests by the middle of the century 115 million people worldwide could be blind, compared to 36 million people in 2015.

Vision impairment as a result of ageing is said to be one of the main contributors to rising eye-sight problems in our growing elderly populations.

Researchers said action was need on a global, regional and country level to slow the acceleration of vision impairment.

The study, led by Professor Rupert Bourne and funded by the Brien Holden Vision Institute, analysed the prevalence of blindness and vision impairment in 188 countries between 1990 and 2015.

Its findings revealed that 2.05 per cent of men and 2.79 per cent of women in the UK have moderate to severe eye sight problems, with 0.16 percent and 0.23 percent respectively being blind.

These Kodi add-ons are still working

Researchers estimated that as ageing populations expand, prevalence rates could see an upturn by 2020.

They predict further increases in the number of cases by 2050 if treatment is not improved with almost 115 million cases of blindness and 588 million people with moderate to severe vision impairment.

Professor Bourne, of Anglia Ruskins Vision and Eye Research Unit, said: “Even mild visual impairment can significantly impact a persons life, for example reducing their independence in many countries as it often means people are barred from driving, as well as reducing educational and economic opportunities.
