There is no dark line marking where the tint begins, so the filtered area blends outward instead of stopping at a border, and the frame stays out of your own peripheral vision while you wear it. Like the rest of the Heritage frames it is hand-cut from Italian cellulose acetate and polished across more than sixty separate steps, which is what keeps a transparent rim looking like glass rather than plastic. The fit is medium: 49-20-145, a 139 mm front, 40 mm of lens.\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\u003eSame notch, two different 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\u003eAll-day indoor use\u003c\/em\u003e\u003cspan\u003eDrawn for people who want the filter on all day rather than only in a bright room.

The 49 mm eye reads small and the 20 mm bridge is wide for it, which lifts the frame and suits a lower nose bridge. Lens height is 40 mm, deep enough for coverage past the pupil without touching the cheek on most faces. Temples are 145 mm. Clear acetate shows fingerprints and skin oils sooner than a dark rim, so keep the cloth handy.\u003c\/p\u003e\n\u003ctable class=\"sxd-tbl\"\u003e\n\u003ctr\u003e\n\u003cth\u003eFrame size\u003c\/th\u003e\n\u003ctd\u003e49-20-145\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\u003eRectangle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCollection\u003c\/th\u003e\n\u003ctd\u003eThe Heritage Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eItalian cellulose acetate\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\u003eEclate Crystal White 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":48028503933077,"sku":null,"price":119.0,"currency_code":"USD","in_stock":false},{"title":"Zero Power \/ FL-41 Dark Tint - Severe Photophobia","offer_id":48028503965845,"sku":null,"price":125.0,"currency_code":"USD","in_stock":false},{"title":"Prescription Lens \/ FL-41 Light Tint - Mild Photophobia","offer_id":48028503998613,"sku":null,"price":169.0,"currency_code":"USD","in_stock":false},{"title":"Prescription Lens \/ FL-41 Dark Tint - Severe Photophobia","offer_id":48028504031381,"sku":null,"price":175.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/5475\/4453\/files\/M1115Blacktf.640.jpg?v=1789806347","url":"https:\/\/www.sleepaxa.com\/products\/sleepaxa-eclate-crystal-white-fl-41-migraine-glasses-crystal-acetate-rectangle-medium-fit","provider":"Sleepaxa","version":"1.0","type":"link"}
