process that needs constant interactions between the eye‚ the nervous system‚ and the brain. When a person looks at an object‚ they are actually seeing the light the object gives off. This light is passed through the lens‚ and then passed through the retina of the eye. From there‚ the light triggers nerve impulses which are then sent to the optic nerve in the brain. In the brain is where that light becomes and image‚ and depending on prior knowledge or comfortability with that image‚ our barin will make

The human eyes are one of the most interesting medical field that are being studied‚ as well as one of the most complex organs that has many features. The eyes are the organs of sight and one of our special senses. Vision is our one of our dominant sense: 70% of all the sensory receptors in the body are in the eyes‚ and almost

Picking up a box from the floor and placing it on a shelf Light entering the eye forms an upside-down image on the retina. The retina transforms the light into nerve signals for the brain. The brain then turns the image right-side up and tells us what we are seeing. Our brain then computes to pick up the box. When a message comes into the brain from anywhere in the body‚ the brain tells the body how to react. the brain as a central computer that controls all bodily functions‚ then the nervous

causes visual impairment‚ often temporary‚ usually in one eye[1][2] When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula. This results in blurred or distorted vision (metamorphopsia). A blurred or gray spot in the central visual field is common when the retina is detached. Reduced visual acuity may persist after the fluid has disappeared.[1] The disease is considered idiopathic but mostly affects white males
