Too wide for my large 6yos face. He is the size of a 7 or 8 year old so I thought we'd be in the clear given the age range advertised is 4 to 10. They fit my adult face comfortably. They are not very dark. The strap is USELESS, literally just stays on for a second but then they fall out again. I must admit I was swayed by the strap when choosing which pair because I knew that he would like to be able to hang them around his neck. Don't make my mistake!! Very frustrating for my child because he so badly wants them to work out. Too bad I already gifted them to him or I would send them back. Not impressed.
