Cutler and Gross 1433 Square Optical

The 1433 is a square optical frame with a 50mm lens width, which is the horizontal measurement of a single lens. Fifty is a small-to-medium size: neat on the face, unlikely to overwhelm narrower features, and easy to wear for long stretches at a desk.

Three colourways. Black is the workhorse. Dark Havana brings the warmth of mottled brown. Smoke Quartz is the interesting one, a translucent grey that softens the frame against the skin.

Acetate, handcrafted by a British house that still does this the slow way.
