As soon as the need for vision correction is identified; contact lenses are a viable option. In fact, they have frequently been used in premature infants, who sometimes have vision problems. With proper care and lens maintenance, infants, young children, teens, and adults of all ages can wear contacts successfully.
We at Eyezone encourage contact lens wear at age of 14 years and above. The real issue for teens is not the age, but whether they are responsible enough to wear and care for contact lenses properly.
