The term “Fovea Distortion” is derived from the fovea centralis which is located in the retina’s center and is responsible for high-acuity human vision.  Sunex lenses with Fovea distortion map this type of behavior and “exaggerate” the central details while trading off the off-axis details. Technically speaking, this results in a higher number of pixels per degree in the center, allowing machine vision algorithms to benefit from a higher resolution in the center field compared to standard f-theta distortion lenses.  The following graph shows the typical angular resolution vs. field angle curve for such a lens:
