Black Crystal Rectangle Eyeglasses N034
Black Crystal N034 is a black-over-crystal rectangular frame with a crisp, modern edge, built as a true full-frame optical piece rather than a cosmetic accessory.
The fit
On paper that's a 51mm lens width, a 18mm bridge and 140mm temples, which in practice means a fit that neither pinches at the nose nor slides down after an hour at a desk.
Frame and finish
The frame is made from layered acetate, which is why the color has that depth instead of looking flat like molded plastic. It's the same material process used across most premium optical frames.
Lenses and prescription
This is an optical frame, so it ships with clear demo lenses in place. Bring it to Optica or your own optician to have your prescription fitted, whether that's single vision, bifocal, progressive or a blue-light coating.
Who it suits
Rectangle frames like this one suit square or angular jawlines well, keeping the look sharp without being oversized.
