You know, we found these while shopping the 50 Mile Garage Sale event in the beautiful Bitterroot Valley in western Montana. We think they have prescription lens so that is why we are listing as "sunglass frame" and not as sunglasses.

We are not opticians or eyeglass experts so in our amateur way, this is how they measure. 
5 5/8" across the top
4" bows from hinge to where it starts to bend down
1 5/8 x 2" lens

We will ship them in a Smith eyeglass container just because we want them to arrive safely and don't have the correct case..
