That cool tone is worth knowing about before you order, because it sets itself against a warm yellow lens instead of blending with it; the tint stays visibly a lens. The geometry is compact and even: 49 mm lenses, a 20 mm bridge and a 139 mm front, with 40 mm of depth. Those proportions suit somebody who moves between a monitor, a laptop and a phone through the day, since a shallower frame would leave the downward glance outside the tinted area.\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\u003eLight in, light out, by wavelength\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.

The 49 mm lens paired with a 20 mm bridge gives a standard nose opening, neither tight nor floating. At 40 mm the lens height is conventional, deep enough to cover a downward glance at a phone without the rim resting on the cheek. Temples of 145 mm are the common length and should need little adjustment.\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 Hybrid Series\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\u003eChrono Gunmetal Black 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":48028519956629,"sku":null,"price":119.0,"currency_code":"USD","in_stock":false},{"title":"Prescription Lens","offer_id":48028519989397,"sku":null,"price":169.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/5475\/4453\/files\/M1115Black2.669copy.jpg?v=1789807122","url":"https:\/\/www.sleepaxa.com\/products\/sleepaxa-chrono-gunmetal-black-computer-glasses-medium-rectangle-139-mm-front","provider":"Sleepaxa","version":"1.0","type":"link"}
