A new report shows well over two billion people around the world are suffering with sight issues.
This is according to the World Health Organization on Thursday as it raises awareness of World Sight Day.
It says least two.two billion people globally have visual impairment, and that around half of them have visual impairment that could have been prevented or has yet to be addressed.
The majority of people with visual impairment around the world are over 50 years old.

The WHO says the prevalence of distance visual impairment in low- and middle-income regions is four times higher than high-income regions.
