Traffic: frame shape, face fit and lens technology
Eyewear search has three distinct vocabularies and most stores serve only one. Shape queries name the frame: round metal, cat eye, aviator, browline, rimless. Fit queries describe the wearer: sunglasses for a wide face, small frames for a narrow bridge, glasses for a low nose bridge. Lens queries name the technology: polarised, photochromic, blue light filtering, category 3 tint. Each set deserves its own collection with copy explaining what the term means and which frames qualify, plus the measurement ranges that make a fit claim true. Prescription and plano demand also split, and a store that sends both to the same page loses one of them.
