Yes, it is a fact. Sunglasses have rounded up their edges in many ways; from cat-eyes to half-frames, circular is the 'key' . But let's be more specific!
No. 1 CAT EYE
Choosing either the 3/4 or the 1/4 round always create a cheerful appeal.
No. 2 THE HALF FRAME
Certainly the upper frame will take all the attention creating an edgier feel.
No. 3 THE PERFECT CIRCLE
The typical blast from the past that will give you utmost character.
No. 4 THE PRINTED FRAME
We have seen prints on everything; why not on accessories too.
No. 5 THE THIN FRAME
Emphasize on the round shape choosing the thin, minimal frame.
