Question

how you would encourage him to wear
glass??

Answer 1

I will tell  him that if he will wear the glasses he will be able to do good in his class assignments. Weak eyes can results to complete blindness. So I will tell him that if he will wear it then this will reduce his headache and he can also get rid off the specs by eating green leafy food.

Answer 2

I will say him as he will look handsome and intelligent in the classroom
