Description
The Calder Square is a clean rectangular frame with a strong brow, balanced everyday proportions, and polarized TAC lenses. It is the easiest entry point into the Alan Hugh Shades edit: structured enough to add presence without turning into a costume piece.
Why it works
The rectangular silhouette adds definition around the eyes while the lightweight polycarbonate construction keeps the frame approachable for daily wear. It is especially suited to driving, travel, and bright outdoor conditions where glare reduction matters.
