Hi B.,
We found out when my son had just turned 4 that he needed glasses too (he is now 8), we also had Avesis at the time...and we went to COSTCO. Ironically, I was just saying yesterday to a friend that the first pair of glasses he had were the best frames that I felt he has had so far. They do a great job...we have since changed insurance co's and we go to a place close to our home, Arizona Vision. Not sure if they take AVESIS, but they do have kids frames (not sure what size they start out at though) - those two places are worth a try though...good luck!
