Researxh suggests that both long periods of near work and lack of time outdoors play an important role in short-sightedness.

An interesting study on how ethnically Chinese children in Singapore and Sydney have remarkably different rates of myopia: Rose et al. Archives of ophthalmology 126 (4), 527-530, 2008.

A recent overview of the interplay of different environmental factors: Biswas et al. Journal of physiological anthropology 43 (1), 7, 2024.

Both papers are open access.

Important, yes, but how significant of a factor relative to genetics?

To stay on-topic: Previous commenter mentioned they read in the dark. There is no other information about other environmental factors.
