1. A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform one or more operations for eye tracking, comprising:
capturing with a first camera a first plurality of visual data of a right eye at a first sampling rate;
capturing with a second camera a second plurality of visual data of a left eye at a second sampling rate, the second plurality of visual data captured during different sampling times than the first plurality of visual data; and
by processing electronics:
based on at least some visual data of the first plurality of visual data and the second plurality of visual data, estimating, as estimated visual data, visual data of at least one of the right eye or the left eye at a sampling time during which visual data of the at least one of the right eye or the left eye for which the visual data is being estimated is not being captured; and
determining eye movement of the at least one of the right eye or the left eye based on at least some of the estimated visual data and at least some visual data of the first plurality of visual data or the second plurality of visual data.
