One of the biomedical engineering bottlenecks in constructing an artificial eye is that the eye is a curved object or hemispherical providing it with the ability to view a wide field of view without distortion. This is a feat that, up to now, electronic microchip technology has not been able to mimic. Researchers at the University of Illinois at Urbana-Champaign have now worked out a way around those problems, using conventional chip manufacturing technology.
