On Medical Mattes this evening we look at World Myopia week which happens from 13th – 19th May. Myopia Awareness week is being observed worldwide, primarily to raise awareness, with emphasis on juvenile-onset myopia. Globally, myopia is a leading cause of avoidable vision loss. By the year 2050, nearly half of the world's population will be myopic. To tell us more about juvenile myopia we’re joined by Dr Steph Lindeque, a specialist ophthalmologist.
