Eyeglasses have become a fashion accessory. You should pick frames that you like, and be sure that they are also comfortable, safe, and sturdy. Lenses are available in safety glass, regular plastic, and polycarbonate. Glass lenses can be heavy and tend to slide down a kid's nose. Plastic or polycarbonate lenses are lighter and safer than glass, but they scratch easily.
Some kids choose to wear contact lenses instead of glasses.
If your ophthalmologist says you can wear either glasses or contact lenses, talk it over with your parents. Some kids don't want to be bothered with contact lenses because it takes extra time each day to clean, disinfect, and store them properly. Some kids don't mind the added responsibility. For specific medical advice, diagnoses, and treatment, consult your doctor.
