Sleepaxa Artisan Espresso Brown Gaming & Computer Glasses – Yellow Blue-Light Filter

Artisan Espresso Brown

A warm espresso rectangle with the balanced, unremarkable-in-the-best-way proportions most faces actually want.

Espresso Brown is a deep roasted brown with a faint red tone underneath, and it is one of the few colors that softens a rectangular frame instead of sharpening it. The acetate is Italian, hand-cut from a solid block, then polished over more than sixty separate steps. The numbers are 51-20-145 on a 141 mm front with a 41 mm lens height, which is almost the geometric center of our range: nothing here is exaggerated. For all-day screen work that middle ground is the point, because a frame with no extreme dimension has nothing that starts to irritate at hour six.

The transmission curve, in plain figures

• 0% measured transmission below 400 nm - UV fully blocked
• 36.8% at 450 nm - the short-wavelength load from screens is cut without removing it
• 76.5% at 550 nm - working brightness retained
• Rising to 95.0% at 700 nm - color balance on screen stays usable
• Luminous transmittance 76.5%, Filter Category 1

All 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. Individual response varies.

Will the Artisan Espresso Brown fit you?

If you have never measured your own glasses, this is the easiest frame to start with, because it sits near the middle of everything. Artisan is 51-20-145 on a 141 mm front. Most adults who have worn off-the-shelf frames without complaint fall within a couple of millimeters of those figures. Check the first number inside your arm: 49 to 53 mm and you are in range. Well outside that in either direction, and one of our small or wide frames will serve you better.
