A level upper rim sits closer to the brow than a curved one, which closes the gap where overhead light normally slips in above the lens. Underneath it there is 45 mm of lens depth, near the deep end of the range, so the rose field runs from brow to well below the pupil. Measurements are 55-17-140 on a 141 mm front, a wide fit rather than an extra-wide one. The transparent version lets all of that geometry work without a dark border framing your face.\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\u003eCoverage above, two tints below\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 photophobia, every day\u003c\/em\u003e\u003cspan\u003eThe lighter of the two rose tints, drawn for all-day indoor wear.

The 55 mm eye is large and the 17 mm bridge relatively narrow for it, which keeps the frame from riding low. Lens height of 45 mm is deep, so check your brow-to-cheekbone distance if you have a short face. Temples are 140 mm, on the shorter side, and suit a head that finds 150 mm arms overlong.\u003c\/p\u003e\n\u003ctable class=\"sxd-tbl\"\u003e\n\u003ctr\u003e\n\u003cth\u003eFrame size\u003c\/th\u003e\n\u003ctd\u003e55-17-140\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFront width\u003c\/th\u003e\n\u003ctd\u003e141mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLens height\u003c\/th\u003e\n\u003ctd\u003e45mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFit\u003c\/th\u003e\n\u003ctd\u003eWide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShape\u003c\/th\u003e\n\u003ctd\u003eFlat-top square\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\u003eRegent Crystal Clear 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":48028497182869,"sku":null,"price":129.0,"currency_code":"USD","in_stock":true},{"title":"Zero Power \/ FL-41 Dark Tint - Severe Photophobia","offer_id":48028497215637,"sku":null,"price":135.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ FL-41 Light Tint - Mild Photophobia","offer_id":48028497248405,"sku":null,"price":179.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ FL-41 Dark Tint - Severe Photophobia","offer_id":48028497281173,"sku":null,"price":185.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/5475\/4453\/files\/regent-cc-migraine-front-2048_4e673c94-9675-4f95-86c3-9837cd495e69.png?v=1789805977","url":"https:\/\/www.sleepaxa.com\/products\/sleepaxa-regent-crystal-clear-fl-41-migraine-glasses-clear-flat-top-square-wide-fit","provider":"Sleepaxa","version":"1.0","type":"link"}
