Is the child having vision problems?

A high school student is wearing glasses, but sometimes they see objects doubled.

I spend a lot of time looking at the tablet screen while listening to lectures, so I'm worried whether it's because of that or for some other reason.

Sometimes, they say that if you just rest a little, you'll be okay again.

I'm thinking about visiting the ophthalmology department.

As a high school student, it's hard to find time to go to the hospital.

I think I should visit once using the weekend.

I hope it's just because you're tired.
