Ever been told you’re a tough nut to crack? Instead of taking it up with your therapist, own it in our Tough Nut readers. These acorn-shaped acetate beauties are perfect for those with average-sized heads looking to dip a toe in the mystical waters of geometric frames. More wearable than most uniquely shaped frames, this unisex pair is singular nonetheless, with seven sides and a sprinkle of funky patterns to rival your own complexity. Try them as traditional full-lens readers or progressives, and watch how these frames re-frame being called “complicated” as a compliment.

Frame width is the primary way we determine fit. It’s the horizontal diameter of the entire frame width.

Other Technical measurements
Like most brands of glasses, the measurements of eyebobs glasses can be found on the inside of the temple arm. The first number indicates the lens width (46mm) and the second number is the bridge (23mm). If you already have a pair of glasses you like, you can use those measurements as a reference.
