Thanh is a student in Can Tho City, Vietnam. Like many children in her community, she had struggled with her vision for years without receiving proper eye care.
Four years ago, after telling her parents she could not see clearly, she was taken to a private glasses shop and given a pair of glasses for mild refractive error. But when she put the glasses on at home, she found that they didn't help her vision, so she stopped wearing them after just a few days.
Without regular eye checks or the correct prescription, Thanh’s eyesight continued to worsen.
