WebMay 24, 2024 · In optics, the “optical density” usually refers to the absorbance of a material. For example, a “50% neutral density filter” would cut the intensity of transmitted light in half, without favoring one color over another and without making any brighter or dimmer patches. A neutral density filter would make a good lens for untinted sunglasses. – rob ♦ WebSep 23, 2024 · Optical density is a term applied to how well light passes through a material. If light is little affected passing through it, that is, if almost all the light goes through it that goes into it, it has a very low optical density. Like clear glass.
