Explanation:

The first paragraph explains what myopia is (symptoms, common name, affected population). The second paragraph talks about when myopia typically begins (childhood). There's no indication of a scientific vs non - scientific explanation split. Also, there's no mention of improvement methods.

Answer:

They present a primary cause and then other potential causes.
