A 48 mm lens is on the small side, yet the front still measures 142 mm across, because 23 mm of that span is bridge. The practical result is a frame whose weight rests on the nose over a wide, shallow contact area instead of a narrow one, which is what keeps a pair from creeping down over a long stretch at a keyboard. Temples run 148 mm, three millimeters past the common length. The acetate is Italian, cut by hand from a solid block and brought to finish across more than sixty steps, and umber gives it a warm brown depth that changes noticeably under a desk lamp.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sxd-sec\"\u003e\n\u003cdiv class=\"sxd-k\"\u003eThe lens\u003c\/div\u003e\n\u003ch2\u003eOne lens, five measured points\u003c\/h2\u003e\n\u003cul class=\"sxd-list\"\u003e\n\u003cli\u003e0% measured transmission below 400 nm - UV fully blocked\u003c\/li\u003e\n\u003cli\u003e36.8% at 450 nm - the short-wavelength load from screens is cut without removing it\u003c\/li\u003e\n\u003cli\u003e76.5% at 550 nm - working brightness retained\u003c\/li\u003e\n\u003cli\u003eRising to 95.0% at 700 nm - color balance on screen stays usable\u003c\/li\u003e\n\u003cli\u003eLuminous transmittance 76.5%, Filter Category 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"sxd-note\"\u003eAll figures are single-lens spectrophotometer measurements from our own laboratory reports for this lens, tested to EN ISO 12312-1, ANSI Z80.3 and AS\/NZS 1067.1.

At 23 mm the nose opening is far wider than a typical 18 to 20 mm, so it suits a broader or flatter bridge and will feel loose on a narrow one. The 48 mm lens keeps the overall look modest despite the 142 mm front. Temples of 148 mm reach a little further back than standard. The 40 mm lens height is ordinary, clearing the cheek on most faces.\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\u003c\/th\u003e\n\u003ctd\u003eDayActive yellow screen lens · 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\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 with DayActive lenses\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","offer_id":48028518908053,"sku":null,"price":119.0,"currency_code":"USD","in_stock":false},{"title":"Prescription Lens","offer_id":48028518940821,"sku":null,"price":169.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/5475\/4453\/files\/M1115Black2.57.jpg?v=1789807046","url":"https:\/\/www.sleepaxa.com\/products\/sleepaxa-grandeur-umber-brown-computer-glasses-medium-rectangle-23-mm-bridge","provider":"Sleepaxa","version":"1.0","type":"link"}
