The eye lens is a biological organ which functions as an optical element. What better subject
for a special section of the Journal of Biomedical Optics? The role of the lens in the eye is
twofold: to aid the cornea in refraction and to alter the focus of the eye providing clear vision
over a range of distances. With age, lenticular function is altered. The focusing capacity
decreases, making it harder and harder to see close objects clearly. In addition, there is an
increase in light scatter and fluorescence. In some cases the structure of the lens undergoes …
