  • Patent number: 5235441
    Abstract: A method of constructing holographic lenses for correction of a person's deficiencies comprises splitting a filtered laser beam onto an object under consideration and thence to a photographic film, and simultaneously conducting the other beam to the film as a reference whereby the interference patterns between the two beams form a hologram which is developed by ordinary photographic process. The hologram can be visualized by the user of the lens when the reference beam is conducted to the developed film. The lenses are individualized to correct for the particular optical deficiencies of a user by varying the focal distance.
