A design approach to low‐vision device development—vision multiplexing—was introduced recently. This approach has been applied successfully to the design of novel electronic and optical low‐vision aids. This paper discusses the application of the vision‐multiplexing concept to spectacle lens design to address issues of low vision and to resolve problems of color discrimination and glare in driving. Because spectacles are considered a fashion accessory as much as they are a vision aid, cosmetic considerations are critical to the design of such aids. Spectacle‐borne devices that are not concealed or attractive are unlikely to be used widely. Efforts to combine the functionality of vision multiplexing with improved appearance are illustrated.
Eli Peli (2002) studied this question.
