School Myopia

For students in primary schools and/or high schools, daily homework could damage their eyes. At this age, their eyes are not mature yet, so if they keep doing their homework, keep looking at their books at a close distance to their books from day to after day, sooner or later, they will have 'school' myopia. In China, reportedly, 30% of primary school students begin to wear glasses, and 90% of college students are wearing glasses (??? gross exaggeration - and more common in GD/GX perhaps). This damage to their eyes are is irreversible, so both teachers and parents should be alarmed. In order to protect student's eyes, teachers should not give assignment to students every day.

dubious logic and dubious facts!  Parents should help with better reading environment and reading tools too

Those changes are minor. Otherwise, good work!
