bridge_fit: Maker label "Low Bridge Fit" mapped using Oakley's published definition (src_oakleysi_oo9244_2556).

Notes: Two WebFetch extractions of this URL with differently worded prompts; only values both returned identically are recorded. Size label is Oakley's tech-spec 'Size' value; the page gives no lens width, nose bridge, temple length, lens height, overall frame width, UPC or EAN, so those are omitted (the mm figure in the size label is not labelled as a specific dimension). Tech-spec 'Fit' row read 'Regular'. Low Bridge Fit Sylas is labelled L (136mm) while standard Sylas OO9448 is M (133mm). An earlier fetch of the base URL (no variant parameter) gave 'Lens category: Sun Lenses'; the paired variant-URL extractions both gave 3. Lens name has no 'Polarized'. Size follow-up (2026-09-25T08:33:27Z): lens/bridge/temple(arm)/lens height/frame width from Oakley's own Standard Issue site (oakleysi.com), two agreeing WebFetch extractions; that page served OO9448F-0258 with size L (136mm), matching this variant's oakley.com size label. SportRx (retailer) prints different, self-measured figures for some styles (e.g. Holbrook: Lens Width 57mm / Bridge 17mm / Temple 128mm / Frame Width 132mm); not recorded.
