I've long been surprised at how pervasive bad eyesight is, and often at a very young age. It seems like an adaptive trait. Why is it so common to have poor eyesight? What other aspects of human development suffer so much that seem so important for survival?

Insulin resistance is another. It keeps your brain alive when you’re starving, but it destroys millions of pancreases in societies with an over-abundance of food.

It may not be related to nature. I remember reading research on how sunlight and focusing on distant objects is really important for developing proper eyesight. The current issues with eyesight could be a side-effect of spending more time in doors and only staring at things within 20 to 30 ft.
