2. troland
   unit used to express a quantity proportional to retinal illuminance produced by a light stimulus. When the eye is viewing a surface of uniform luminance, the number of trolands is equal to the product of area in square milimetres of the limiting pupil, natural or artificial, by the luminance of the ...

5. Troland
   The `troland` (symbol `Td`), named after Leonard T. Troland, is a unit of conventional retinal illuminance. It is meant as a method for correcting photometric measurements of luminance values impinging on the human eye by scaling them by the effective pupil size. The troland typically refers ...
