Nothing about the geometry changes: a 50 mm eye, a 19 mm bridge that spaces the lenses wide, 145 mm temples and a 135 mm front. Lens depth stays at 33 mm. Small frames like this are the ones people actually keep on through a whole evening, because there is very little of them resting anywhere. The trade is coverage, since a shallow lens leaves more of your lower field unfiltered when you look down.\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 tint for evening, one for night\u003c\/h2\u003e\n\u003cdiv class=\"sxd-grid\"\u003e\n\u003cdiv class=\"sxd-card\"\u003e\n\u003cb\u003eAmber lens\u003c\/b\u003e\u003cem\u003eFrom sundown, indoors and out\u003c\/em\u003e\u003cspan\u003eMeasured transmission at 450 nm, the melanopsin peak, is 0.10%.

A 19 mm bridge is on the wide side and works best with a broader nose bridge. With only 33 mm of lens height, expect a high tinted field and plenty of open space beneath the rim. Temples are 145 mm. Larger faces will find this one undersized rather than merely small.\u003c\/p\u003e\n\u003ctable class=\"sxd-tbl\"\u003e\n\u003ctr\u003e\n\u003cth\u003eFrame size\u003c\/th\u003e\n\u003ctd\u003e50-19-145\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFront width\u003c\/th\u003e\n\u003ctd\u003e135mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLens height\u003c\/th\u003e\n\u003ctd\u003e33mm\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\u003eRetro oval cat-eye\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCollection\u003c\/th\u003e\n\u003ctd\u003eThe European 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\u003eRiviera Jet Black 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":48028316106901,"sku":null,"price":129.0,"currency_code":"USD","in_stock":true},{"title":"Zero Power \/ Sleep Red Tint - Night \/ Indoor Only","offer_id":48028316139669,"sku":null,"price":135.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ Sleep Amber Tint - Day \u0026 Evening \/ Indoor + Outdoor","offer_id":48028316172437,"sku":null,"price":179.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ Sleep Red Tint - Night \/ Indoor Only","offer_id":48028316205205,"sku":null,"price":185.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/5475\/4453\/files\/riviera-front-2048_26206f17-c772-4ed6-b9a3-174da8a64482.png?v=1789804190","url":"https:\/\/www.sleepaxa.com\/products\/sleepaxa-riviera-jet-black-sleep-glasses-small-oval-cat-eye-amber-red-lenses","provider":"Sleepaxa","version":"1.0","type":"link"}
