Novel vision aids for people suffering from Age-Related Macular Degeneration

Hillenbrand, Matthias GND; Mitschunas, Beate; Homberg, Sarah; Sinzinger, Stefan GND

Degeneration (AMD), a disease that causes progressive damage to the central part of the retina. People suffering from AMD usually experience growing dark or blurred spots in the center of their vision which render them unable to read texts, to drive cars, or to recognise faces. Current vision aids for AMD patients are mainly based on the magnification and/or the redirection of the full field of view which will inevitably result in a loss of information at the outer parts of the field of view. In contrast, we present different optical principles for the redirection of the central part of the field while the loss of information at the boarders is kept to a minimum. Our focus is on highly integrated, nonelectric, spectacle-like systems. Possible principles include the field dependent displacement and magnification/reduction of the object information as well as a deliberately induced distortion. Our contribution includes the mathematical and optical modelling of the imaging setup, numerical simulations as well as the presentation of first experimental results.
