This is something 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.

this is the side view the front view is somewhere else

they're based on an old children's 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
