Like most teenagers, Trinh, 15, finds it more interesting to talk about her friends than her eyesight. She has a friend who helps her with maths, a friend she walks to school with, and another whose house she goes to to study and hang out.
We are sitting in Trinh’s small room, painted blue, in the home she shares with her sister, parents and grandmother. Her family are farmers, and they raise chickens and cows, as well as growing fruit and vegetables like papaya and prickly pear.
Trinh quite likes helping her family, especially cooking. She helps prepare the vegetables and chop the meat. She's good at it – she and her mother make us lunch while we're there, and it’s delicious.
It’s clear Trinh enjoys her studies, particularly maths and literature, but school wasn’t always easy for her.
