At 22 mm it is the most open nose fit in the range, and that single number changes who the frame works for: anyone whose glasses leave marks, anyone with a low or flat bridge, anyone who cannot tolerate pressure across the top of the nose on a bad day. The round oval outline follows from that, soft-cornered and even. A 52 mm eye, 142 mm temples and a 140 mm front keep it medium, while the 43 mm lens height still gives real coverage under the pupil.\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\u003eTwo rose depths on one quiet frame\u003c\/h2\u003e\n\u003cdiv class=\"sxd-grid\"\u003e\n\u003cdiv class=\"sxd-card\"\u003e\n\u003cb\u003eFL-41 Light\u003c\/b\u003e\u003cem\u003eLong indoor stretches\u003c\/em\u003e\u003cspan\u003eWhere the dark lens is for a bright room, this one is for the whole day.

Its defining measurement is the 22 mm bridge, the widest here, which suits a low or flat nose bridge and spreads contact over a larger area. If standard bridges pinch you, start with this one. The 52 mm eye is on the smaller side, so the frame reads compact despite the 43 mm lens depth. Temples are 142 mm, slightly shorter than standard, which suits a smaller head.\u003c\/p\u003e\n\u003ctable class=\"sxd-tbl\"\u003e\n\u003ctr\u003e\n\u003cth\u003eFrame size\u003c\/th\u003e\n\u003ctd\u003e52-22-142\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFront width\u003c\/th\u003e\n\u003ctd\u003e140mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLens height\u003c\/th\u003e\n\u003ctd\u003e43mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFit\u003c\/th\u003e\n\u003ctd\u003eMedium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShape\u003c\/th\u003e\n\u003ctd\u003eRound oval\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCollection\u003c\/th\u003e\n\u003ctd\u003eThe Comfort Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLens options\u003c\/th\u003e\n\u003ctd\u003eFL-41 Light or Dark · zero power or prescription\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUV protection\u003c\/th\u003e\n\u003ctd\u003e100% UV400, both tints\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sxd-sec\"\u003e\n\u003cdiv class=\"sxd-k\"\u003eIn the box\u003c\/div\u003e\n\u003cul class=\"sxd-list\"\u003e\n\u003cli\u003eHalcyon Slate Black frame in your chosen FL-41 tint\u003c\/li\u003e\n\u003cli\u003eHard case and microfiber cleaning cloth\u003c\/li\u003e\n\u003cli\u003eSpectrophotometer report reference for your lens\u003c\/li\u003e\n\u003cli\u003eOne-year frame warranty, six-month lens warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Sleepaxa","offers":[{"title":"Zero Power \/ FL-41 Light Tint - Mild Photophobia","offer_id":48028496396437,"sku":null,"price":139.0,"currency_code":"USD","in_stock":true},{"title":"Zero Power \/ FL-41 Dark Tint - Severe Photophobia","offer_id":48028496429205,"sku":null,"price":145.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ FL-41 Light Tint - Mild Photophobia","offer_id":48028496461973,"sku":null,"price":189.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ FL-41 Dark Tint - Severe Photophobia","offer_id":48028496494741,"sku":null,"price":195.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/5475\/4453\/files\/halcyon-migraine-front-2048_f19aa16e-213a-47fb-a816-0375a62ff480.png?v=1789805939","url":"https:\/\/www.sleepaxa.com\/products\/sleepaxa-halcyon-slate-black-fl-41-migraine-glasses-round-oval-open-22mm-bridge","provider":"Sleepaxa","version":"1.0","type":"link"}
