APPARATUS FOR MEASUREMENT OF MACULAR PIGMENT OPTICAL DENSITY OR LENS OPTICAL DENSITY OF AN EYE

摘要

This invention relates to apparatus for use in the measurement of the optical density of macular pigment in the human eye, and to apparatus for the use in measuring the lens optical density of a human eye. The invention is particularly applicable to flicker photometers, which are used to measure the macular pigment in the human eye.
