Halcyon runs 22 mm, wider than anything else in the range, which lifts the whole front off the sides of the nose and spreads contact across a larger area. Around that sits a 52 mm eye in a soft round oval, 43 mm deep, on a 140 mm front with 142 mm temples. For long evening sessions that geometry matters more than shape does: the frame you forget about is usually the one that is not concentrating its weight in one place.\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 long evening, red for the short night\u003c\/h2\u003e\n\u003cdiv class=\"sxd-grid\"\u003e\n\u003cdiv class=\"sxd-card\"\u003e\n\u003cb\u003eAmber lens\u003c\/b\u003e\u003cem\u003eExtended evening wear\u003c\/em\u003e\u003cspan\u003eMeasured transmission at 450 nm, the melanopsin peak, is 0.10%.

The headline number is the 22 mm bridge, which suits a wide or flat nose bridge and is the widest opening in this lineup. With a 52 mm eye and 43 mm of lens height, the aperture is tall and rounded, covering well below the pupil. Temples are 142 mm.
