15-year-old Alexandre, who is from Yaounde in Cameroon, was a little embarrassed when he first noticed the white spot in his left eye that would go on to cause him a lot of pain and discomfort.
“When I started seeing a spot in my eye I was feeling very strange, and everyone started realising it so I was just feeling awkward,” he told us.
As a result Alexandre didn't initially tell his family about the problems he was having and it wasn't until his mother was helping him study one day after school that she realised something was wrong. When Alexandre told her he couldn’t see, she took him to see a doctor at Yaounde Central Hospital. There, Alexandre was diagnosed with a cataract in his left eye.
