Optometrists recommend that babies have their first eye examination between six and nine months of age to ensure their eyes are healthy, eye alignment and eye muscle movements are developing properly, and the eyes are focusing together. A number of serious eye conditions exist that can be identified during their first eye exam. If left uncorrected, these conditions can result in serious vision problems. Vision development continues into the preschool years – depth perception, eye-hand coordination, and visualization skills. Doctors of Optometry recommend children have at least one eye exam between the ages of two and five, and yearly after starting school.
