Children develop full vision in each eye over the course of their first year. Young babies cannot see beyond a few feet and you should not be concerned if they cannot recognise your face from a distance for their first three or four months. Watery eyes are common in young babies as the ducts which carry the tears away from the eye surface are not fully open for the first few months. However, if this problem does not clear up by the child's first birthday, check with your general medical practitioner. Signs of eye problems that need advice from your optician or healthcare professional in babies and infants include persistent or recurrent eye infections and if you notice that the eyes do not move together perfectly, eg when looking at an object straight ahead one eye is pointed slightly outward (squint). When your child is three or four years old, if they are having difficulty recognising shapes, colours or showing no interest in pictures in storybooks, you will find the majority of opticians will have the necessary tests to conduct a full eye examination. Your child does not have to be able to read to have their sight tested.
