   • 2012, Julie Dorsey, Philipp Slusallek, Rendering Techniques ’97, →ISBN:

     Tumblin's model aims to match a perceived quality known as brightness, measured in brils, so that the real world brightness and display brightness can be equated.

   • 2014, William Ross McCluney, Introduction to Radiometry and Photometry, Second Edition‎, page 360:

     many of the old units-such as the nox, phot, glim, skot, and scot (identical), as well as the bril and brill (different)—are so antiquated as to be of interest only to the historian.

• brildraer
• leesbril
• sonbril
• veiligheidsbril

• → Sotho: borele

From Middle Dutch beril (“beryl”), from Latin beryllus (“beryl”), from Ancient Greek βήρυλλος (bḗrullos), from Prakrit [Term?] (compare Sanskrit वैडूर्य (vaiḍūrya, “a cat's eye gem; a jewel”)), from Dravidian. Probably named after the city Velur (modern day Belur) in southern India. The first glasses, manufactured in Italy around 1300, were made of beryl. The meaning “toilet seat” is newer and derived from the similarity in shape to a single eyeglass. The word thus forms a doublet of beril (“beryl”).
