There is no age limit to wear contacts, even babies can wear them and so can seniors. It is encouraged to begin to wear contact at the age of 11-14 by many eye care professors. If one is responsible enough and are able to care for contact lenses, he/she is a candidate for contacts. You should make the decision together with your son, and his eye doctor.
