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.
