• A patient's blind phakic eye with clear media, the subject of previous light exposure studies, was exposed for 60 minutes to light from a standard operating room microscope (Zeiss OpMi-6) filtered through an infrared filter. A typical acute photic retinopathy lesion was produced. Two and a half months later, the eye was exposed for 60 minutes to light filtered simultaneously through an ultraviolet filter and an infrared filter. Despite blocking both the ultraviolet and infrared light, and despite reducing the overall light energy by approximately one fourth because of the combination of filters, a typical acute photic retinopathy lesion was produced by the transmitted light, the energy of which was essentially all within the visible spectrum.
