Astor Crystal Clear
A transparent front that lets the tint be the only color in the room.
Clear fronts change how a tinted lens reads. Against a see-through rim there is no dark border competing with the amber or the red, so what people notice is the lens rather than the frame around it. Astor Crystal Clear carries the same extra-wide geometry as its black sibling, 55 mm eye, 18 mm bridge, 150 mm temples and a 147 mm front, with a 43 mm lens depth. The practical effect of that depth is coverage below the pupil, where bedside and ceiling lamps usually come in. It is a large frame worn lightly.
Two tints, two jobs
Two tints, two different times of night
Amber lensLate-afternoon and evening, either side of the doorThe amber tint reads 0.10% at 450 nm and 0.48% at 500 nm. Part of the green band survives, rising to 40.5% at 550 nm and 66.6% at 560 nm. It carries 100% UV protection (UV400).
Red lensLights-on nights, indoorsThe blue and green bands are gone outright, with zero measured transmission from 380 to 560 nm. What gets through is long-wavelength, 49.7% at 600 nm and 92.9% at 700 nm, with 100% UV protection (UV400).
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 Astor fit you?
This is an extra-wide fit at 147 mm across the front, so measure your own temple-to-temple width before choosing it. The 18 mm bridge sits high and open, which suits a lower or flatter nose bridge. At 43 mm the lens is deep, and on a shorter face the lower rim may reach the cheek when you smile. Temples run 150 mm. Anyone who currently wears a medium frame should expect this one to feel considerably larger.
