The front measures 139 mm, squarely medium, and the lens runs 40 mm deep, so the tinted field covers the straight-ahead view and the first part of your downward gaze, which is where ceiling panels put their light. Temples are 145 mm. For someone who works under overhead fluorescents and wants glasses that read as ordinary, this shape draws no attention at all.\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 lens for the whole day, one for the bright room\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, morning to night\u003c\/em\u003e\u003cspan\u003eThe lighter of the two rose tints, drawn for all-day indoor wear.

The 19 mm bridge is wide for a 52 mm eye, which helps if narrower frames leave pressure marks. At 40 mm the lens is moderately deep, covering the straight-ahead view without meeting the cheek. Temples run 145 mm, a standard length. If your current glasses already grip at the temples, look at the wider Regent instead.\u003c\/p\u003e\n\u003ctable class=\"sxd-tbl\"\u003e\n\u003ctr\u003e\n\u003cth\u003eFrame size\u003c\/th\u003e\n\u003ctd\u003e52-19-145\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFront width\u003c\/th\u003e\n\u003ctd\u003e139mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLens height\u003c\/th\u003e\n\u003ctd\u003e40mm\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\u003eWayfarer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCollection\u003c\/th\u003e\n\u003ctd\u003eThe American Classic 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\u003eHudson 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":48028489121941,"sku":null,"price":129.0,"currency_code":"USD","in_stock":true},{"title":"Zero Power \/ FL-41 Dark Tint - Severe Photophobia","offer_id":48028489154709,"sku":null,"price":135.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ FL-41 Light Tint - Mild Photophobia","offer_id":48028489187477,"sku":null,"price":179.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ FL-41 Dark Tint - Severe Photophobia","offer_id":48028489220245,"sku":null,"price":185.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/5475\/4453\/files\/hudson-jb-migraine-front-2048_b5eee1dc-b405-4fc0-b157-65bf90b1bd02.png?v=1789805664","url":"https:\/\/www.sleepaxa.com\/products\/sleepaxa-hudson-jet-black-fl-41-migraine-glasses-medium-wayfarer-139mm-front","provider":"Sleepaxa","version":"1.0","type":"link"}
