Bad eyesight, especially myopia, was much rarer than today, with the leading hypothesis being that not enough sunlight exposure over one's growing years leads to it.

I don't understand this phrasing - are you implying I'm not aware of these people? People...had bad eyesight before. Now they have bad eyesight with corrective lenses.
