Abstract
Embodiments disclosed herein include eyewear that provides controlled variable light attenuation and color enhancement based on an input received from a user, a sensor and/or a signal from a control circuit. In some embodiments, the eyewear includes an optical filter system with two or more defined filter states that are adapted to improve color vision in different environments. The optical filter system can be incorporated into a lens having any desired curvature, including, for example, cylindrical, spherical or toroidal. The lens can include one or more functional components. Examples of functional components include color enhancement filters, chroma enhancement filters, a laser attenuation filter, electrochromic filters, photoelectrochromic filters, variable attenuation filters, anti-reflection coatings, interference stacks, hard coatings, flash mirrors, anti-static coatings, anti-fog coatings, other functional layers, or a combination of functional layers.
