Vesper avoids that by running a 21 mm bridge, the widest in this group, against a small 49 mm eye. The circles end up spaced rather than stacked, which keeps the shape from looking studious. Lens height is 42 mm and the front 137 mm, so although the eye size is modest the lenses are nearly as tall as they are wide, giving a genuinely round aperture rather than a squashed one. Temples run 145 mm. It is a distinctive outline that still fits a standard face.\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 to soften the evening, red to end it\u003c\/h2\u003e\n\u003cdiv class=\"sxd-grid\"\u003e\n\u003cdiv class=\"sxd-card\"\u003e\n\u003cb\u003eAmber lens\u003c\/b\u003e\u003cem\u003eEvening, indoors and outdoors\u003c\/em\u003e\u003cspan\u003eThe curve starts near zero, 0.10% at 450 nm, then lifts through 40.5% at 550 nm to 66.6% at 560 nm and 96.3% at 600 nm.

The 21 mm bridge is the widest here, so it suits a broad or high nose bridge and will feel loose on a narrow one. A 49 mm eye with 42 mm of lens height makes the aperture close to circular, covering more below the pupil than the small eye size implies. Temples are 145 mm. If round frames have pinched you before, the wide bridge is the reason to try this one.\u003c\/p\u003e\n\u003ctable class=\"sxd-tbl\"\u003e\n\u003ctr\u003e\n\u003cth\u003eFrame size\u003c\/th\u003e\n\u003ctd\u003e49-21-145\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFront width\u003c\/th\u003e\n\u003ctd\u003e137mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLens height\u003c\/th\u003e\n\u003ctd\u003e42mm\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\u003eRound\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCollection\u003c\/th\u003e\n\u003ctd\u003eThe Designer 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\u003eVesper 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":48028396060821,"sku":null,"price":129.0,"currency_code":"USD","in_stock":true},{"title":"Zero Power \/ Sleep Red Tint - Night \/ Indoor Only","offer_id":48028396093589,"sku":null,"price":135.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ Sleep Amber Tint - Day \u0026 Evening \/ Indoor + Outdoor","offer_id":48028396126357,"sku":null,"price":179.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ Sleep Red Tint - Night \/ Indoor Only","offer_id":48028396159125,"sku":null,"price":185.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/5475\/4453\/files\/vesper-front-2048_b977b4eb-068c-45d1-962b-756911ef8e37.png?v=1789804451","url":"https:\/\/www.sleepaxa.com\/products\/sleepaxa-vesper-jet-black-sleep-glasses-round-frame-wide-bridge","provider":"Sleepaxa","version":"1.0","type":"link"}
