Zephyr Jet Black
Six sides and fifty millimeters of lens, which is an unusual pair of facts.
Zephyr is the outlier in the range twice over. Its outline is hexagonal, with angled facets instead of a curve or a straight rim, and its lens height is 50 mm, taller than anything else we list. On a 140 mm front with a 53 mm eye and an 18 mm bridge, that depth produces a tinted field that extends well below the normal line of sight, which is the part of your vision that picks up light from a phone held in your lap. Temples measure 145 mm.
Two tints, two jobs
Amber through the evening, red at the end of it
Amber lensEvening screens, indoors or outAt the melanopsin peak of 450 nm this lens passes 0.10%. Longer wavelengths open up quickly, 66.6% at 560 nm and 96.3% at 600 nm, so color stays usable. Filter Category 1 at 50.5% luminous transmittance means it is rated for outdoors as well as indoors.
Red lensLate indoor hoursZero transmission across 380 to 560 nm makes this the darker of the two. Long wavelengths carry the image: 5.8% at 570 nm, 49.7% at 600 nm. Filter Category 3, 14.9% luminous transmittance, indoor use only.
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 Zephyr fit you?
The 140 mm front makes Zephyr a comfortable medium to slightly wide fit. Its 18 mm bridge is average and suits most nose shapes. The number to weigh is the 50 mm lens height, the tallest here: you need real distance between brow and cheekbone or the lower facet will rest on your face. Temples are 145 mm. If you have a short midface, pick a 32 to 40 mm lens instead of this one.
