Because of the photochemical toxic effects of blue light on the retina of experimental animals,[1],[2],[3] it is natural to extend the concern to humans.[4][sup] subThis may be important in aphakic eyes as evidenced from the work of S. Lerman[sup]5sub shown in [Figure 1]. This figure rep-resents transmission characteristics of nor-mal human crystalline lens from 6 months to 82 years of age. X-axis is the wavelength in nanometers and Y-axis is the percent transmission of light. The human lens pro-vides excellent near ultraviolet and blue light filtration from age 25 onwards. Post-cataract surgery this natural protection is lost ...
