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 half of the cerebral cortex is involved in some aspect of the visual processing. Only the anterior one sixth of the eye is visible. (Martini‚ 2009) The accessory structures of the eye include the eyebrows‚ eyelid‚ conjuctiva‚ lacrimal apparatus‚

consist of decreased visual acuity‚ lessened ability to adapt to darkness and dim light‚ decreased accommodation to see near and far objects‚ loss of peripheral vision‚ atrophy of lacrimal glands‚ and difficulty discriminating similar colors. Presbyopia is the inability to focus or accommodate due to a loss of flexibility of the lens‚ causing decreased near vision. Cataracts are also very common in older adults; they cause the eye to have increased lens opacity in which reduces visual acuity and causes

Perception is a way of knowing and gaining knowledge. Expectation‚ the belief about the way an event should happen or behave‚ and previous knowledge‚ understanding and skills we gain after experience play significant roles when gaining knowledge. They frame and lead us into imagine before we experience. Our five senses let us see‚ smell‚ taste‚ feel and hear. People think that we believe what we see. However‚ we see what we believe. Lipman’s suggestion criticises the false of our senses and perspectives

diagnosed with a genetic disease‚ recessive retinitis pigmentosa (RP)‚ which results in degeneration of the photoreceptor cells. A patient with RP has a progressive loss of visual acuity‚ progressive night blindness‚ and progressive loss of peripheral vision. The patient’s best corrected visual acuity is currently 20/200 with a visual field restriction of 12 degrees. The patient bumps into objects in the room and gets disoriented as to the location of the bathroom or the door to the hallway. (Learning

Evaluate the evidence that visual perception involves bottom-up and top-down processing. The perceptual system is comprised of a of a diverse range of senses including visual‚ auditory‚ olfactory and tactition; the perceptual system is part of the nervous system‚ which contains millions of nerve cells called receptors that sense and respond to a plethora of sensory stimuli including light‚ sound and temperature. The act of perceiving rather than merely sensing enables us to analyse and make sense

bench in the distance witch was obvious before sunset became difficult to see after the sun had set. This can be explained by the amount of light visible in the surroundings‚ as our cones are less sensitive to dim light then rods. Another change in visual features after it became dark was that it was harder to distinguish between different types of colours. Even thought there is a lesser amount of light. In my opinion‚ this change cannot be attributed to the diminished source of light. When our surroundings

we’re relieved the non-sighted cannot see. Reading Oliver Sacks’ case “To See and Not See”‚ about a man named Virgil‚ gives me a new and interesting perspective on blindness. I have a friend who is partially deaf. She and I communicate with visual cues and our communication is helped by the fact that she can hear some sound and can read lips. In contrast‚ I cannot say I have had an occasion to spend time with a non-sighted person. While reading about Virgil‚ however‚ I felt that I was given
