Abstract: An interactive system and method for testing the sunlight sensitivity of a subject is provided herein. The system includes a computer generated imaging device for displaying a number of realistic situational scenes on a viewing screen situated opposite an observation port. The subject first views the scenes under a variety of lighting conditions created by an illumination source and indicates a level of visual discomfort through actuating a response indicator. The test is then repeated using a series of lens filters inserted between the observer and the screen and a set of new responses is recorded wherein the lens offering the most comfortable or pleasing protection against the light is determined for the subject.
