The American Classic Series · FL-41
Hudson Jet Black
The wayfarer outline, drawn with enough bridge that the frame rests off the nose instead of on it.
Hudson pairs a 52 mm eye with a 19 mm bridge, which is generous for an eye that size and is the reason the frame carries its weight on the brow line rather than the nose pads. The front measures 139 mm, squarely medium, and the lens runs 40 mm deep, so the tinted field covers the straight-ahead view and the first part of your downward gaze, which is where ceiling panels put their light. Temples are 145 mm. For someone who works under overhead fluorescents and wants glasses that read as ordinary, this shape draws no attention at all.

FL-41 LightMild sensitivity, morning to nightThe lighter of the two rose tints, drawn for all-day indoor wear. It cuts the same rose-band notch as FL-41 Dark but at a higher overall transmittance. The full spectrophotometer report for this tint is being finalized and will be published here. 100% UV protection (UV400).
FL-41 DarkHarsh overhead lightingMeasured transmission is 7.9% at 420 nm and 13.8% at 450 nm, so the blue band is attenuated across its width rather than cut. At 520 nm the lens passes 12.6%, which is the green band being pulled down in the same sweep. From 44.2% at 570 nm the curve climbs to 100% above 670 nm.
All figures are single-lens spectrophotometer measurements from our own laboratory reports for this lens, tested to EN ISO 12312-1, ANSI Z80.3 and AS/NZS 1067.1. Individual response varies.
Fit
Will the Hudson fit you?
Hudson is a medium frame at 139 mm across the front, so it suits an average temple width. The 19 mm bridge is wide for a 52 mm eye, which helps if narrower frames leave pressure marks. At 40 mm the lens is moderately deep, covering the straight-ahead view without meeting the cheek. Temples run 145 mm, a standard length. If your current glasses already grip at the temples, look at the wider Regent instead.
