Abstract

A lens containing a chromophore distributed in or on the lens such that the lens functions as a virtual pupil in adjusting to light. The lens can be intraocular or extraocular.

Claims

1. An extraocular polymeric lens, the lens comprising

at least two concentric peripheral zones, and

an inner central zone defining a visual axis;

the polymeric material in the peripheral zones containing at least one light-activated chromophore that darkens when light-activated, the chromophore

in or on the lens polymeric material,

distributed in substantially concentric circles outward from the central area, and

uniformly increasing in concentration from the outer periphery of the central area to an outermost periphery of the outermost concentric circle;

the central zone

lacking the chromophore, or

containing a chromophore that does not absorb visible light, or

containing a chromophore at a minimal concentration.

2. The lens of claim 1 configured in spectacles.

3. The lens of claim 1 configured in a telescope.

4. The lens of claim 1 configured in a camera.

5. The lens of claim 1 configured in a microscope.

6. The lens of claim 2 configured as a clip-on lens.

7. The lens of claim 1 configured in goggles.
