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

I recommend going to an pediatric Ophthalmologist. Babies eyes are still developing and it's best to see a specialist instead of an optometrist to best diagnose your baby's condition. Try contacting Dr. Pauline Santiago of Medical City, St. Luke's QC and Polymedic. She's an excellent pedia ophtha. Hope this helps!
