The Chrono rectangle underneath measures 49-20-145 on a 139 mm front with a 40 mm lens. Those are unremarkable numbers on purpose. A rectangle in this size range imposes very little on the face, so the decision you are actually making is which tint you want in front of your eyes and when.\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\u003eAmber through the evening, red at the close\u003c\/h2\u003e\n\u003cdiv class=\"sxd-grid\"\u003e\n\u003cdiv class=\"sxd-card\"\u003e\n\u003cb\u003eAmber lens\u003c\/b\u003e\u003cem\u003eAfter sunset, indoors or out\u003c\/em\u003e\u003cspan\u003eTransmission sits at 0.10% at 450 nm, the melanopsin peak, and at 0.48% at 500 nm.

The 20 mm bridge spaces the lenses well apart, which suits most nose shapes without gripping. Lens height of 40 mm gives balanced coverage above and below the pupil. Temples are 145 mm, the standard length. Choose between this and Chrono Gunmetal Black on color alone, since the fit is identical.\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 options\u003c\/th\u003e\n\u003ctd\u003eAmber or Red · 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\u003eChrono Brunt Umber frame in your chosen 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 \/ Sleep Amber Tint - Day \u0026 Evening \/ Indoor + Outdoor","offer_id":48028466151573,"sku":null,"price":119.0,"currency_code":"USD","in_stock":true},{"title":"Zero Power \/ Sleep Red Tint - Night \/ Indoor Only","offer_id":48028466184341,"sku":null,"price":125.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ Sleep Amber Tint - Day \u0026 Evening \/ Indoor + Outdoor","offer_id":48028466217109,"sku":null,"price":169.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ Sleep Red Tint - Night \/ Indoor Only","offer_id":48028466249877,"sku":null,"price":175.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/5475\/4453\/files\/M1115Black2.606.jpg?v=1789804835","url":"https:\/\/www.sleepaxa.com\/products\/sleepaxa-chrono-brunt-umber-sleep-glasses-umber-rectangle-medium-fit","provider":"Sleepaxa","version":"1.0","type":"link"}
