The visual system

Let’s examine the foveal vision a bit closer. This type of vision concerns the focussing of the eye. The eye can try to follow a certain moving object. We then have pursuit eye movements. Alternatively, the eye can jump from one place to another place. We are then dealing with saccadic eye movements. Important parameters are now the location of the focus, as well as the dwell time, which is the amount of time which the eye focusses on a certain point.
