Abstract

The spectral transmission of the human lens is not uniform in the visible spectrum. The lens absorbs strongly in the ultra-violet and short wavelength region and is nearly transparent in the long wavelength region. The absorption of the lens increases during life, with the lens appearing obviously "yellower" in advanced years. Although these facts are well-accepted, there are two controversies concerning the age-related changes in the human lens: (a) are age-related increases in density a linear or an accelerated function of the age in years and (b) is the spectral density function of an "old" eye a scalar multiple of its spectral density function at an earlier period?
