1. A method comprising:
displaying an image on an eyewear device worn by a user;
detecting a gaze direction of a pupil of the user;
identifying a first region of the image that corresponds to the gaze direction of the pupil; and
modifying a brightness value of pixels in the image based on the gaze direction such that pixels in the first region of the image are set to a first brightness value and pixels in a second region of the image are set to a second brightness value that is lower than the first brightness value, the second brightness value being computed based on a continuous curve relative to the first brightness value.
