From Ian Simmons, Westcliff on Sea, Essex, UK
I favour the idea, one of several raised, that exposure to wide open space outdoors is what reduces myopia rates in children, rather than light exposure. Indoors the eye can only look as far as the walls, while outdoors it needs to deal with vistas of hundreds of metres, if not kilometres. Without this, is it surprising eyes become adapted to seeing close up at the expense of being able to see what is far away?
