Vision Multiplexing

An optical engineering concept for low-vision aids that involves presenting multiple views or visual channels simultaneously to compensate for reduced visual function. In the context of assistive technology, vision multiplexing allows users to see both a wide field of view and a magnified detail view at the same time, overcoming the inherent trade-off in traditional magnification devices where increasing magnification reduces the visible area. This approach is particularly valuable for people with central vision loss (who need magnification for detail) or peripheral vision loss (who need a wider field of view), enabling them to access both perspectives without continuously switching between aids.
