side, eye movements called saccades rotate both eyes so that the image now falls on the fovea. Likewise saccades are used to point the fovea at each word in this sentence. 2) Vergence ◦ If you look (i.e. direct the foveas) from a far object to a near one, vergence eye movements are generated; convergence when looked from far to near and divergence when looking from near to far. 3) Pursuit ◦ When an object that we are looking at moves, the image is kept still on the retina by means of a pursuit eye movement (e.g. tracking a ball or your moving finger).
our head, an eye movement very similar to pursuit is elicited whose function is also to keep the image still on the retina. it is generated by a different neural circuit, the VOR. The VOR does not need a visual stimulus. 5) Optokinetic Reflex (OKR) ◦ The VOR does not work well for slow prolonged movements. In this case vision, through the OKR, assists the VOR. The OKR is activated when the image of the world slips on a large portion of the retina and produces a sense of self motion If an image appears to the side, eye movements called saccades rotate both eyes so that the image now falls on the fovea. 6) Nystagmus 7)sacalic
