The lens sits far out from the nose and high on the face, so a small rectangle still delivers 40 mm of depth over the pupil. It is hand-cut from Italian cellulose acetate and polished across more than sixty separate steps, which is why the 142 mm front holds a crisp edge instead of a moulded one. Temples run 148 mm. For a narrow face that cannot tolerate bridge pressure, nothing else here comes close.\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 small rectangle, 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\u003eEveryday indoor filtering\u003c\/em\u003e\u003cspan\u003eThe lighter of the two rose tints, drawn for all-day indoor wear.

It suits a low or broad nose bridge and anyone who gets pressure marks from standard fittings. The 40 mm lens is deep relative to the small eye, so coverage is better than the outline implies. Temples are 148 mm, slightly long. A wide face will find the 48 mm eye too small.\u003c\/p\u003e\n\u003ctable class=\"sxd-tbl\"\u003e\n\u003ctr\u003e\n\u003cth\u003eFrame size\u003c\/th\u003e\n\u003ctd\u003e48-23-148\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFront width\u003c\/th\u003e\n\u003ctd\u003e142mm\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\u003eGrandeur Umber Brown 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":48028502458517,"sku":null,"price":119.0,"currency_code":"USD","in_stock":false},{"title":"Zero Power \/ FL-41 Dark Tint - Severe Photophobia","offer_id":48028502491285,"sku":null,"price":125.0,"currency_code":"USD","in_stock":false},{"title":"Prescription Lens \/ FL-41 Light Tint - Mild Photophobia","offer_id":48028502524053,"sku":null,"price":169.0,"currency_code":"USD","in_stock":false},{"title":"Prescription Lens \/ FL-41 Dark Tint - Severe Photophobia","offer_id":48028502556821,"sku":null,"price":175.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/5475\/4453\/files\/M1115Black2.58.jpg?v=1789806273","url":"https:\/\/www.sleepaxa.com\/products\/sleepaxa-grandeur-umber-brown-fl-41-migraine-glasses-acetate-rectangle-23mm-bridge","provider":"Sleepaxa","version":"1.0","type":"link"}
