Its eye is 56 mm, the largest we cut, while the bridge is 15 mm, the narrowest. That combination is what gives the navigator outline its look and also what makes it fit closely: a narrow bridge keeps a big lens from drifting outward, so 44 mm of lens depth stays where it is aimed. The 137 mm front keeps the overall width medium despite the large eye, and 140 mm temples run slightly short. It suits a face with a defined nose bridge that narrow fittings do not slide off.\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\u003eWide field, two tint depths\u003c\/h2\u003e\n\u003cdiv class=\"sxd-grid\"\u003e\n\u003cdiv class=\"sxd-card\"\u003e\n\u003cb\u003eFL-41 Light\u003c\/b\u003e\u003cem\u003eMild sensitivity, all-day\u003c\/em\u003e\u003cspan\u003eThis is the everyday tint.

The 15 mm bridge is the narrowest here, which suits a well-defined or higher nose bridge and will feel tight if yours is broad. At 44 mm the lens is deep, giving coverage well below the pupil. Temples are 140 mm, a touch short, so they suit a smaller head. If the bridge pinches, Halcyon opens to 22 mm.\u003c\/p\u003e\n\u003ctable class=\"sxd-tbl\"\u003e\n\u003ctr\u003e\n\u003cth\u003eFrame size\u003c\/th\u003e\n\u003ctd\u003e56-15-140\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFront width\u003c\/th\u003e\n\u003ctd\u003e137mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLens height\u003c\/th\u003e\n\u003ctd\u003e44mm\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\u003eNavigator\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCollection\u003c\/th\u003e\n\u003ctd\u003eThe Navigator 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\u003eAltair Jet 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":48028500459669,"sku":null,"price":129.0,"currency_code":"USD","in_stock":false},{"title":"Zero Power \/ FL-41 Dark Tint - Severe Photophobia","offer_id":48028500492437,"sku":null,"price":135.0,"currency_code":"USD","in_stock":false},{"title":"Prescription Lens \/ FL-41 Light Tint - Mild Photophobia","offer_id":48028500525205,"sku":null,"price":179.0,"currency_code":"USD","in_stock":false},{"title":"Prescription Lens \/ FL-41 Dark Tint - Severe Photophobia","offer_id":48028500557973,"sku":null,"price":185.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/5475\/4453\/files\/altair-migraine-front-2048_00075d3c-6cda-4cff-9e8b-2e1c57d6201a.png?v=1789806168","url":"https:\/\/www.sleepaxa.com\/products\/sleepaxa-altair-jet-black-fl-41-migraine-glasses-navigator-shape-56mm-eye-on-a-15mm-bridge","provider":"Sleepaxa","version":"1.0","type":"link"}
