Catalogue research

Glasses size by brand

Analysis of 7,128 current glasses model-sizes across 39 brands: average lens width, observed size range and average lowest price.

Method. One observation is one distinct model and published lens width, so the same frame stocked by several retailers is counted once while genuine size options remain separate. Obvious source errors outside 35–75 mm are excluded, and only brands with at least 30 observations appear.
