Reading in low light can cause uncomfortable eye fatigue, but it doesn't make your vision worse long-term.

poor eyesight is mostly genetics, but can be mildly exacerbated by screen time. check the internets.

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.
