1. A visor system comprising:
a camera mounted within an environment and configured to capture a plurality of images of a face of a person in the environment;
a visor mounted within the environment and having a plurality of pixels arranged contiguously, an optical state of the visor being adjustable by selectively operating each respective pixel of the plurality of pixels with a respective pixel optical state selected from a plurality of pixel optical states, each pixel optical state in the plurality of pixel optical states having a different opacity such that the respective pixel blocks a different amount of light from passing through a corresponding area of the visor; and
a controller operably connected to the camera and to the visor, the controller being configured to receive the plurality of images from the camera and, for each respective image in the plurality of images:
determine, based on the respective image, at least one position on the visor at which a light source shines through the visor into an eye of the person;
snap each of the at least one position on the visor to a grid defined on a surface of the visor, the grid including uniformly distributed points on the surface of the visor, each of the at least one position on the visor being snapped to a nearest point in the grid defined on the surface of the visor;
determine, based on the at least one snapped position on the visor, an updated optical state for the visor to block the light source from shining through the visor into the eye of the person; and
operate the visor to display the updated optical state.
