Although there is no agreed date on when exactly your child needs an eye examination, most experts agree that children should have a thorough, in-person eye examination when they are 3-5 years old. This will ensure your child's vision is developing well without evidence of eye diseases. Usually, an infant is examined at birth by a pediatrician. Some doctors suggest that the next comprehensive examination after birth should be between six months to one year and repeated before the child joins kindergarten, even when they have no evidence of eye problems. Others have suggested that the child be examined every two years. Children can develop eye conditions in early childhood such as crossed eyes, lazy eye, delay in development, etc., thus needing an examination.
