Generalizing over kids is rife with traps anyway. For example - different age groups (and sub cultures) have different role models to follow/copy/emulate If the 20 somethings find it useful for example - it could trigger the cool factor for adolescents and hence other kids down the chain. Peer pressure, conformity, being cool and fitting in are huge factors for teens, and if their role models use them then they will be open to them too. Heck people can wrap their heads around wearing their underwear visibly, I think cyborg glasses could be an easy sell. (Alternatively If younger kids start using it (perhaps unlikely) then the older kids may even say "that's for kids" and stay clear.) If the peer group approves, then the product will be fine. edited for clarity.
