K.D.
It really depends on the level of responsibility that the child has. I got mine at 12 or 13. My 10 yr old got her's this summer. She actually prefers to wear her glasses more than her contacts, but she is able to wear them and take care of them. Her Ophthalmologist has her in 1 day contacts so she wears them, takes them out and throws them away. No need to worry about cleaning and storing.
