Up to what head size is this good for?
LINA C My son is 3 years old and the glasses fit him great! They fit snuggly but i think the will adjust to his head size the more he wears them. Probably by 4 Years i will have to get bigger glasses. They are sturdy and love the fact that they have no hinges because he can't break them
DAVID K The glasses are small. Bought for a average size two-year old, but were too small. Maybe best for a one-year old.
