Most frames that go deep also go wide, which is exactly what makes them awkward in a meeting. Here the outline stays narrow and formal, square corners and a level brow, while the lens still reaches well below the pupil. The result is a frame that covers the screen in front of you without extending past your temples. Measurements are 54-18-145; the 18 mm bridge is generous for a front this narrow and stops the frame gripping.\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\u003eTwo tints for one working day\u003c\/h2\u003e\n\u003cdiv class=\"sxd-grid\"\u003e\n\u003cdiv class=\"sxd-card\"\u003e\n\u003cb\u003eFL-41 Light\u003c\/b\u003e\u003cem\u003eScreens, from morning on\u003c\/em\u003e\u003cspan\u003eIndoor wear, all day.

The 18 mm bridge is generous for that width, which keeps pressure off the sides of the nose. The 39 mm lens height is deep for a medium frame: good coverage below the pupil, but the rim sits closer to the cheek on a short face. Temples are 145 mm. If you are between sizes, the wider Regent is the next step up.\u003c\/p\u003e\n\u003ctable class=\"sxd-tbl\"\u003e\n\u003ctr\u003e\n\u003cth\u003eFrame size\u003c\/th\u003e\n\u003ctd\u003e54-18-145\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\u003e39mm\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\u003eProfessional square\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCollection\u003c\/th\u003e\n\u003ctd\u003eThe Executive Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLens options\u003c\/th\u003e\n\u003ctd\u003eFL-41 Light or Dark · 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\u003eSterling Jet Black frame in your chosen FL-41 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 \/ FL-41 Light Tint - Mild Photophobia","offer_id":48028499411093,"sku":null,"price":129.0,"currency_code":"USD","in_stock":true},{"title":"Zero Power \/ FL-41 Dark Tint - Severe Photophobia","offer_id":48028499443861,"sku":null,"price":135.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ FL-41 Light Tint - Mild Photophobia","offer_id":48028499476629,"sku":null,"price":179.0,"currency_code":"USD","in_stock":true},{"title":"Prescription Lens \/ FL-41 Dark Tint - Severe Photophobia","offer_id":48028499509397,"sku":null,"price":185.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/5475\/4453\/files\/sterling-migraine-front-2048_9c500797-fc77-4ddd-8835-5bdf1f8753f4.png?v=1789806130","url":"https:\/\/www.sleepaxa.com\/products\/sleepaxa-sterling-jet-black-fl-41-migraine-glasses-professional-square-deep-lens-on-a-medium-front","provider":"Sleepaxa","version":"1.0","type":"link"}
