"Create personalized computer eye models to simulate an individual's vision quality using optical and mechanical engineering software. Eye-related industries can benefit from custom computer eye models to simulate visual performance, predict the effects of treatment options, and develop or improve technologies that interface with the eye. For instance, existing schematic paraxial eye models have long been used to estimate refractive corrections or as optical placeholders for an eye. However, these models are inadequate for large pupils and wide angles because they use an equivalent refractive index instead of the true gradient index of the natural crystalline lens. Furthermore, real eyes vary widely in dimensions and ocular surface profiles and schematic models only generalize for entire populations."
