High-resolution foveal imaging and micro-psychophysics reveal that the human oculomotor system finely adjusts drift motion of the eye in an acuity task to enhance retinal sampling, achieving sub-cell ...
The results of this test are written as a fraction, such as 20/20 -- the number for normal visual acuity. The top number represents 20 feet-- that's the standard distance in testing. The bottom ...
A research team has been investigating the question of how we perceive a stable environment despite constant eye movements. The result: rapid and smooth eye movements are based on different mechanisms ...
