Ray-Ban 3699 Sunglasses

Our sizes read lens–bridge (e.g. 54-18mm). Frame width ≈ 2 lenses + bridge + ~10 mm of hinges, and it's what decides the fit (*lens widths assume an 18 mm bridge). Pick a frame about as wide as your face; ±2 mm on the lens feels the same.

1. WidthNo gap at your temples and no pinching. The frame ends right where your face ends.
2. BrowsThe top of the frame follows your brow line, brows just visible above it.
3. EyesYour eyes sit near the middle of each lens, not at the inner edges.
4. NoseThe bridge rests without sliding when you look down or leaving red marks.
5. CheeksThe frame doesn't touch your cheeks when you smile.

Arms a little loose or tight? An optician can adjust most acetate and metal frames in minutes.
