Cyan stands out because most people default to black, brown, or tortoise. The crystal finish keeps the brightness in check. You're getting colour without it being opaque or blocking your face entirely. Thick rectangles provide substantial framing that works if you want your glasses to be noticed and remembered. The cyan reads as intentional and modern, not accidental or trendy. These suit people with strong personal style who aren't worried about their glasses matching every outfit. The thickness adds presence, the cyan adds personality, and the crystal keeps everything from tipping into overwhelming. They're bold but versatile, which is the balance most bold frames fail to hit.
