Poor eyesight is something that affects millions in the world but in many cases it can be cured.
Cataracts is a common eye condition which can be fixed by a simple surgery.
In poorer countries it can be more difficult to fix but charity Sightsavers works to fund operations for people who can not afford it.
Ayshah's got the story of a man in Malawi who is having the operation to give him back his sight.
It means he will be able to see his grandson for the first time.
