This abstract also discusses the role of the lens in myopic eyes. The lens of myopic eyes does not vary its thickness in relationship to focal distance, as it's supposed to. Time outdoors is also highlighted. I haven't read the whole article, but time outdoors has recently been found to be a deterrent to myopia development and progression, that is, the more time outdoors children spend, the less likely they are to be myopic.
From the text:
"The ciliary muscle may play a greater role in emmetropization and myopia than previously thought. Time spent outdoors, not near work, may be the more important environmental variable in myopia. The effect of time outdoors shows an important interaction with a substantial genetic contribution to the risk of myopia."
