The Custom Junior Soft progressive is designed specifically to help reduce the onset of myopia in young people. Myopia develops in childhood, when the eye grows faster than the optics contained therein. Myopia is increasing massively. In 2010, 2 billion people were short-sighted. By 2050, according to the World Health Organization (WHO), 5 billion people will already be short-sighted, or 50% of the world’s population. Long days of screen work (close-up work) and a lot of time under artificial light are the trigger among others.
