Yes, but I think the GP was talking about learning, forming new (different) brain connections, because most near-sighted people navigate the world with blurry vision for at least a few minutes daily, sometimes more. (personally, since my eyesight without glasses or contacts is pretty bad, no more than 15 mins until I get annoyed with the difficulty spotting small objects and go for my glasses :p gonna laser those puppies one day, maybe. it's amazing living in an age where they can actually fix this sort of thing, shame if I didn't take advantage of it)
