Although our frame sizes could be used for children as young as 5, we believe our product is best suited for children 8 years or older. This is more due to the testing procedure and the ability of a child to properly participate in the vision assessment. There are cases when a child simply wants glasses, or wants to please an adult with the “right” answer, which can lead to an incorrect assessment. In addition, children below the age of 9 have a risk of developing “lazy eye” and hence should be examined by a vision care specialist.
