Abstract

The invention teaches the implementation of a contact lens that features large depth of focus and with a performance that is substantially independent of the specific diffraction problem of the viewer. The contact lens is based on the principle of pinhole optics applied to standard corrective contact lenses, even with no refractive power, and utilizes photochromatic materials characterized by a light absorption that increases with increasing levels of illumination.
