A new eyewear company called Meteor Horn Eyewear is breaking into the custom buffalo horn eyewear biz. How it works, you send a picture to Meteor and they will draw 3 designs to fit your face, you will also need a PD (Pupillary Distance) and temple length for the best fit. Other style options are available on the site as well.
The styles range from classic to vintage to funky. Temple designs have the option of mother of pearl inlays or a more architectural look.
This is a new company, they have stock buffalo horn eyewear as well as custom styles.
