OG exemplary drawing
 
1. Eyewear, comprising:
a frame;
a camera supported by the frame and configured to generate images;
a processor configured to process the images; and
a first optical assembly and a second optical assembly coupled to the frame and each configured to receive and pass a real-world image, wherein the first optical assembly and the second optical assembly comprise an eye electrochromic lens including an eye region configured to pass the real-world image to a user's eye, and a camera electrochromic lens including a camera region configured to pass the real-world image to the camera, wherein the eye electrochromic lens and the camera electrochromic lens are isolated;
wherein the eye electrochromic lens comprises a first liquid crystal display filled with a material having a first chemistry and a second liquid crystal display filled with a material having a second chemistry, wherein the first chemistry and the second chemistry are different, wherein the first liquid crystal display has a first fill opening configured to receive the material having the first chemistry, and the second liquid crystal display has a second fill opening configured to receive the material having the second chemistry.
 
8. A method of operating eyewear having:
a frame;
a camera supported by the frame and configured to generate images;
a processor configured to process the images; and
a first optical assembly and a second optical assembly coupled to the frame and each configured to receive and pass a real-world image, wherein the first optical assembly and the second optical assembly comprise an eye electrochromic lens including an eye region configured to pass the real-world image to a user's eye, and a camera electrochromic lens including a camera region configured to pass the real-world image to the camera, wherein the eye electrochromic lens and the camera electrochromic lens are isolated;
wherein the eye electrochromic lens comprises a first liquid crystal display filled with a material having a first chemistry and a second liquid crystal display filled with a material having a second chemistry, wherein the first chemistry and the second chemistry are different, wherein the first liquid crystal display has a first fill opening configured to receive the material having the first chemistry, and the second liquid crystal display has a second fill opening configured to receive the material having the second chemistry, comprising the steps of:
the processor controlling the eye electrochromic lens of each of the first and second optical assemblies to selectively control the passing of the real-world image to the user's eye; and
the processor controlling the camera electrochromic lens of each of the first and second optical assemblies to selectively control the passing of the real-world image to the camera.
 
13. The method of claim 8, wherein the frame has a first opening configured to pass the real-world image to the eye region, and a second opening configured to pass the real-world image to the camera region.
