I don't know if this will help much or not. My son was 4.5 when he got his glasses, but he needed to wear them all the time, so it is a different situation. We constantly told him "glasses go on the face or in the case," it eventually got shortened to "face or case" but after a few weeks we didn't even have to say it anymore, I guess he got so tired of hearing me say that that it was just easier to take good care of his glasses, lol.
