Children should have an eye exam by no later than 6 months of age, then again by age 3, and just before starting school. School-age children need an exam every two to three years after that if they have no visual problems. If your child requires eyeglasses or contact lenses, schedule visits every 12 months.
Prescriptions change frequently, because vision matures along with your child. Your optometrist will also ensure that your child has the visual skills necessary for succeeding in school, such as using the eyes as a team, peripherial vision, ease of focusing from distance to near and eye/hand coordination.
