With an aging aviation population, the use of intraocular lenses (IOLs) has become common place throughout the world for correcting vision acuity, cataracts and eye injuries. The material which comprises an IOL will cause a change in spectral sensitivity seen by the recipient. This is most notable in color variations while viewing Advance Aviation Displays. The results reported here are for one specific composition of IOL given to us by the manufacturer, and are assumed to be or have been in wide use. Cost limitations required that we used color correction filters to simulate colorized IOLs (not actual colorized lenses), but we attempted to use filters with colors simulating the tints of IOLs in production. Additional information has been gathered on contrast variations that should be followed up with additional testing at a later time.
