What is vestibulo-ocular reflex and how important it is for us?
Vestibulo-ocular reflex The vestibulo-ocular reflex is a reflex which helps us to bring the image we are trying to fixate, on our fovea. The fovea is the center most part of the macula. This tiny area is responsible for our central, sharpest vision. A healthy fovea is key for reading, watching television, driving, and other activities that require the ability to see detail. Unlike the peripheral retina, it has no blood vessels. Instead, it has a very high concentration of cones (photoreceptors responsible for color vision), allowing us to appreciate color. To be clearly perceived, images of the outside world have to slide over retina at a speed of no more than few degrees per second. The images otherwise would appear fuzzy and blurred like a photograph taken with a low shutter speed while camera is moving. If the vestibulo-ocular reflex would not have been in existence, the eyes would have remained anchored in the orbit with every disruptive head movement. In this arbitrary situation,
