This is somthing i made ages ago and never posted, but  toribelliachi Alexander Grey was curious about glasses for his fursona, so i posted this for him to see how i designed them.

they're based on an old childrens glasses design that wrapped around the ear so they wouldn't slip off if the child hung upside down, i modified it so that they could reach the top of the head and wrap around the base of the ear, without restricting moment of the ear too much
