How much can a baby see?
Though a baby's eye movements show that they collect visual information right from birth, they're unable to focus much further than 30cms in their early days. After around a month they can look at the boundaries of close objects, and a month later see finer detail on those objects.
There are still many questions about how much and how far infants can see, but what's clear is that the development of the eyes doesn't finish until the child is several years old. So regular check-ups with your optician are a vital part of protecting your child's health.
