Brown fronts behave differently from black ones at close range: the rim reads as a soft boundary rather than a hard line, which is why a lot of people who dislike how black glasses look in a video call get along with umber. Underneath, the shape is a tidy rectangle measuring 49 mm per lens across a 139 mm front, with a 20 mm bridge and 145 mm temples. The figure to pay attention to is the 40 mm lens depth. On a single large monitor that is enough to keep the top toolbar and the lower status bar inside the tinted field while your head stays still.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sxd-sec\"\u003e\n\u003cdiv class=\"sxd-k\"\u003eThe lens\u003c\/div\u003e\n\u003ch2\u003eCut at the blue end, open everywhere else\u003c\/h2\u003e\n\u003cul class=\"sxd-list\"\u003e\n\u003cli\u003e0% measured transmission below 400 nm - UV fully blocked\u003c\/li\u003e\n\u003cli\u003e36.8% at 450 nm - the short-wavelength load from screens is cut without removing it\u003c\/li\u003e\n\u003cli\u003e76.5% at 550 nm - working brightness retained\u003c\/li\u003e\n\u003cli\u003eRising to 95.0% at 700 nm - color balance on screen stays usable\u003c\/li\u003e\n\u003cli\u003eLuminous transmittance 76.5%, Filter Category 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"sxd-note\"\u003eAll figures are single-lens spectrophotometer measurements from our own laboratory reports for this lens, tested to EN ISO 12312-1, ANSI Z80.3 and AS\/NZS 1067.1.

A 49 mm lens with a 20 mm bridge spreads the load across the nose rather than pinching it. The 40 mm depth is the number that decides comfort here: deep enough to cover a full monitor at arm's length, shallow enough to clear the cheekbone when you smile.
