ADJUSTABLE APODIZED LENS APERTURE
First Claim
1. An optical element comprising a photochromic material, the photochromic material being configured such that when the photochromic material is exposed to excitation energy an apodized aperture operable to transmit visible light through the optical element is formed, wherein variance of the excitation energy causes corresponding adjustment of the apodized aperture.

Abstract
An adjustable apodized lens aperture is described which is constructed using photochromic material. As the excitation energy increases, the aperture constricts so as reduce the amount of light through the aperture. As the excitation energy decreases, the aperture dilates so as increase the amount of light through the aperture.
