A procedure for rapidly estimating lens pigment density, based upon metameric matches on the D & H Color Rule, is described. A computational nomograph to convert settings to lens densities is provided. This procedure was validated in a sample 126 normal observers, and shown to produce data comparable to more complex laboratory testing procedures. The speed and simplicity of this procedure suggest that it may be useful for monitoring changes in lens pigment density in groups exposed to high levels of environmental, laboratory or industrial ultraviolet light.
