Ever been told you’re a tough nut to crack? Instead of taking it up with your therapist, own it in our Tough Nut frames. 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 readers or prescription glasses, and watch how these frames re-frame being called “complicated” as a compliment.
- Material: Acetate

Size & Measurement Guide Measurement Guide
Here are the three standard sizes we offer at eyebobs. You will see there are distinct icons associated with each size. Each size is associated with the width of the frame itself.

less than 130mm wide

131mm to 139mm wide
-
W
Wide
more than 140mm wide

Frame width is the primary way we determine fit. It’s the horizontal diameter of the entire frame width.
*Note that you won’t find this number on your glasses.

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.

Lens Width
The horizontal diameter of one lens

Lens height
The vertical diameter of one lens

Bridge Width
The width of the bridge section

Temple Length
The length of the entire temple arm, from the front of the frame to the tip
