The contrast makes the tint look more intentional and less like a coating. Dimensions are a 49 mm eye, 20 mm bridge and 145 mm temples on a 139 mm front, with 40 mm of lens height, which is the most broadly wearable set of numbers in the whole range. If you are buying without trying the frame on first, a medium rectangle in these proportions is the low-risk choice.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sxd-sec\"\u003e\n\u003cdiv class=\"sxd-k\"\u003eTwo tints, two jobs\u003c\/div\u003e\n\u003ch2\u003eAmber for the evening, red for the dark hours\u003c\/h2\u003e\n\u003cdiv class=\"sxd-grid\"\u003e\n\u003cdiv class=\"sxd-card\"\u003e\n\u003cb\u003eAmber lens\u003c\/b\u003e\u003cem\u003eEvening screens and lamps\u003c\/em\u003e\u003cspan\u003eThe amber tint reads 0.10% at 450 nm and 0.48% at 500 nm.

A 20 mm bridge against a 49 mm eye gives an open nose fit that rarely pinches. The 40 mm lens height is the middle of our range: enough coverage to catch a downward look, not so deep that it contacts the cheek. Temples are 145 mm.
