Cutler and Gross 1378 Blue Light Filter Round Opticals (Small)

Seven colourways is a lot of choice for one round frame, and the 1378 uses them well. Black and Striped Dark Green hold the sober end. Dark Turtle and Black on Havana bring classic mottled warmth. Crystal Peach on Striped Brown and Striped Blue Havana on Powder Blue show off the layered two-tone work Cutler and Gross does so well, while Mud on Jet Engine Grey is the most industrial of the set.

This is the small version, with a 49mm lens width. That is the width of one lens, and 49mm puts the frame at the compact end: a close, neat round that suits narrower faces and anyone who finds larger opticals overwhelming.

The blue light filter is in the name, and it is what separates this version from the standard 1378. The frame itself is acetate.

Prescription lenses are fitted before dispatch by Next Level Optical, an authorised Cutler and Gross dealer.
