How will I know if my 11-m.o baby has a blurry vision? Can optical clinics like EO, Sarabia, etc. check babies' eyes?

Ophthalmologists in establishments like EO, Sarabia, etc have different approach when it comes to diagnosing eye problems as compared to a trained pedia ophthalmologist. I suggest you go find one. Their approach is more kid-friendly as they're trained to deal with little kids from the very beginning.
