Hudson Crystal Clear keeps the angled temples and sloped brow of the original wayfarer profile, sized at 52-19-145 with a 139 mm front and a 40 mm lens. On a transparent frame the deep lens is easier to live with visually, because there is no heavy border drawing attention to how much of your face the eyewear covers. That makes it a reasonable pick if you have avoided sleep glasses on the grounds that they look like safety equipment.\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 slow down, red to stop\u003c\/h2\u003e\n\u003cdiv class=\"sxd-grid\"\u003e\n\u003cdiv class=\"sxd-card\"\u003e\n\u003cb\u003eAmber lens\u003c\/b\u003e\u003cem\u003eEvening hours, indoors or outdoors\u003c\/em\u003e\u003cspan\u003eThe amber tint reads 0.10% at 450 nm and 0.48% at 500 nm.

The 19 mm bridge gives a wide nose opening against a 52 mm eye. Lens height runs 40 mm, deep enough to filter a downward glance but close to the cheekbone on a compact face. Temples measure 145 mm. Clear rims show smudges more readily, so the cloth in the box earns its place.\u003c\/p\u003e\n\u003ctable class=\"sxd-tbl\"\u003e\n\u003ctr\u003e\n\u003cth\u003eFrame size\u003c\/th\u003e\n\u003ctd\u003e52-19-145\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\u003eWayfarer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCollection\u003c\/th\u003e\n\u003ctd\u003eThe American Classic 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\u003eHudson Crystal Clear 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":48028337864853,"sku":null,"price":129.0,"currency_code":"USD","in_stock":true},{"title":"Zero Power \/ Sleep Red Tint - Night \/ Indoor Only","offer_id":48028337897621,"sku":null,"price":135.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ Sleep Amber Tint - Day \u0026 Evening \/ Indoor + Outdoor","offer_id":48028337930389,"sku":null,"price":179.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ Sleep Red Tint - Night \/ Indoor Only","offer_id":48028337963157,"sku":null,"price":185.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/5475\/4453\/files\/hudson-crystal-front-2048_255ecf4e-824c-4442-8408-c6e8bfa0f0d2.png?v=1789804259","url":"https:\/\/www.sleepaxa.com\/products\/sleepaxa-hudson-crystal-clear-sleep-glasses-clear-wayfarer-medium-fit","provider":"Sleepaxa","version":"1.0","type":"link"}
