Taiwan has one of the world’s highest rates of myopia, alongside most of east Asia and Singapore .

Myopia is a preventable disease in which abnormal elongation of the eyeball causes light to focus in front of the retina instead of on its surface.

By 2050 , almost half the world's population is projected to have it, with corresponding earlier onset, faster progression and greater severity.

A 2010 government initiative “ Tian -tian 120 ” ( 120 every day ) called for all children to spend at least two hours outside a day.

The outdoor time reversed myopia’s upward trend, bringing the rate among primary schoolchildren from more than 50% down to 45% within a few years .
