DD11 got them when she was 9. She is very responsible, and after wearing glasses for a year, decided she wanted to try contacts. Since I've been wearing contacts myself for 24 years, I was very comfortable having her try them. Her Dr. was very supportive. She took the "class" with a couple of older teens who had more trouble than she did. I oversee her to some degree. I keep all the spares and monitor when she needs to change them out (used to be once a month, but her Dr. recently switched her to bi-weekly as her eyes were starting to get dry). She hasn't lost any, but she's torn one here and there. Also, you might want to only purchase 6 months worth at a time. We had an issue with DD's eyes growing as fast as she was, and her presciption changed twice in a year. I buy them from our eye Dr. so that I can give any unopened boxes back to them and exchange them for others. The funny thing now is that she's wearing her glasses more often now. I guess it's "cool" to wear glasses now that she's about to start 6th grade. She still wears the contacts most of the time however. She only used to wear glasses at night before bed, but she's started wearing them all day some days and is bugging me for new frames! I just got her lenses updated in her old frames so she'll have to wait until Jan. for new frames (our vision insurance will pay for new glasses then). It won't cost you anything to have her try contacts, except maybe a "class fee" for her to be instructed on how to put them in and out and care for them. They always provide a trial pair for a couple of weeks and she can decide then if they're for her. Good luck - I'm sure she'll be fine.
