46mm MILTZEN-Keyhole Round Frames Classic Acetate Eyeglasses

There's a reason this shape has stayed in style for over a hundred years. Our Classic Round Acetate Glasses take the iconic keyhole bridge and full-rim round silhouette from early-20th-century downtown New York eyewear, then re-cut it in modern hand-polished tortoise acetate — for a frame that feels as good as it looks.

The 46mm lens width sits comfortably on small to medium faces, while the gently curved keyhole bridge keeps the frame centered without pinching. Subtle silver rivets at the hinges nod to the original hand-assembled construction. The tortoise shell pattern is never repeated — each pair is unique.

Wear them as everyday prescription glasses, swap in blue-light lenses for screen days, or treat them as a sharp style frame. The tortoise pairs with everything from a plain white tee to a structured wool coat.

If you've been searching for that frame — the one your favorite vintage photo is wearing — this is it.
