A typical superimposed representative absorption spectrum of intact human lenses (2–85 years). a- 02, b- 15, c- 20, d- 30, e- 45, f- 60, g- 65 (diabetic), h- 75, i- 80, j-85 years old lenses. A progressive shift in the wavelength of absorption from λ210 nm to λ470 nm was observed. An increase in absorbance was recorded (range 0.25 to = 3.0 - not shown on y - axis) at λ511–520 nm with age.
