What that does in practice is push a small round lens outward and upward, away from the nose and toward the brow, so you get a 42 mm depth of tinted field out of a frame that looks modest from the front. The 137 mm front stays medium and the 145 mm temples are standard. It is the round option for anyone who wants coverage without a large visible frame.\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\u003eOne circle, two rose 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\u003eDaily indoor wear\u003c\/em\u003e\u003cspan\u003eSame notch, less depth.

The 21 mm bridge is wide and sits the frame high, which suits a low nose bridge and keeps a round lens off the cheek. Despite the small eye the lens is 42 mm deep, so coverage below the pupil is better than the outline implies. Temples are 145 mm. Round shapes suit angular faces best.\u003c\/p\u003e\n\u003ctable class=\"sxd-tbl\"\u003e\n\u003ctr\u003e\n\u003cth\u003eFrame size\u003c\/th\u003e\n\u003ctd\u003e49-21-145\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\u003e42mm\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\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCollection\u003c\/th\u003e\n\u003ctd\u003eThe Designer 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\u003eVesper 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":48028497805461,"sku":null,"price":129.0,"currency_code":"USD","in_stock":true},{"title":"Zero Power \/ FL-41 Dark Tint - Severe Photophobia","offer_id":48028497838229,"sku":null,"price":135.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ FL-41 Light Tint - Mild Photophobia","offer_id":48028497870997,"sku":null,"price":179.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ FL-41 Dark Tint - Severe Photophobia","offer_id":48028497903765,"sku":null,"price":185.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/5475\/4453\/files\/vesper-migraine-front-2048_6a1d6d53-cf59-4dcc-99ff-8c42c89459f4.png?v=1789806016","url":"https:\/\/www.sleepaxa.com\/products\/sleepaxa-vesper-jet-black-fl-41-migraine-glasses-round-frame-49mm-eye-and-21mm-bridge","provider":"Sleepaxa","version":"1.0","type":"link"}
