Claim 6:
7. The method of claim 1, wherein:
the first structured light pattern comprises a diffuse and broadband light pattern, wherein the diffuse and broadband light pattern is projected onto the lens of the eyewear with a predetermined intensity for a predetermined amount of time configured to cause a photochromic response of the lens,
the method further comprises obtaining, by the processing circuitry, a subsequent image depicting the face of the person wearing the eyewear and a third reflection pattern generated by projecting light onto the lens of the eyewear after the predetermined amount of time,
wherein determining the one or more optical parameters of the lens comprises:
determining a transmissivity of the lens based on the first reflection pattern and the third reflection pattern; and
determining a photochromism of the lens based on the transmissivity of the lens.
