Dark black acetate on a 134 mm front, 47-20-145, with a 43 mm lens height. Small frames usually give up coverage to get their size down; this one does not, because the lens is nearly as deep as it is wide. Hand-cut from a solid Italian acetate block and polished through more than sixty steps, so the rim edge stays clean where a molded frame would show a seam. It is the least conspicuous way to wear red lens sleep glasses in a shared room.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"sxd-sec\"\u003e\n\u003cdiv class=\"sxd-k\"\u003eTwo tints, two jobs\u003c\/div\u003e\n\u003ch2\u003eOne is for the evening.

This is the small end of the range and the 134 mm front is the figure to compare, because anything you own measuring 140 mm or more is a full size up from this. The 20 mm bridge is generous for a small frame, so it rests instead of clamping. Arms are 145 mm, standard length, and bend to fit at the tip.\u003c\/p\u003e\n\u003ctable class=\"sxd-tbl\"\u003e\n\u003ctr\u003e\n\u003cth\u003eFrame size\u003c\/th\u003e\n\u003ctd\u003e47-20-145\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFront width\u003c\/th\u003e\n\u003ctd\u003e134 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLens height\u003c\/th\u003e\n\u003ctd\u003e43 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFit\u003c\/th\u003e\n\u003ctd\u003eSmall\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShape\u003c\/th\u003e\n\u003ctd\u003eRound\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 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\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\u003eMosaic Dark 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 Red Tint - Night \/ Indoor Only","offer_id":44041224519829,"sku":"SA-MO-DB-SLG-ZP","price":99.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ Sleep Red Tint - Night \/ Indoor Only","offer_id":44041224552597,"sku":"SA-MO-DB-SLG-PL","price":149.0,"currency_code":"USD","in_stock":true},{"title":"Zero Power \/ Sleep Amber Tint - Day \u0026 Evening \/ Indoor + Outdoor","offer_id":48027421409429,"sku":null,"price":93.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ Sleep Amber Tint - Day \u0026 Evening \/ Indoor + Outdoor","offer_id":48027421442197,"sku":null,"price":143.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/5475\/4453\/products\/M1115Black2.0copy.jpg?v=1706023509","url":"https:\/\/www.sleepaxa.com\/products\/sleepaxa-mosaic-dark-black-sleep-glasses","provider":"Sleepaxa","version":"1.0","type":"link"}
