hearing, taste and smell. The human eye is an organ that is responsible for responding to light, focusing and transmitting light through a lens. The human brain consists of 12 cranial nerves that are either motor, sensory or contains both functions. CN Olfactory: primary sensory nerve that allows smell CN Optic: vision; primary sensory nerve CN Oculomotor: CN Trochlear: enables eye to look downward or inward CN Trigeminal: facial sensation; chewing CN Abducens: moves eye laterally CN Facial: contributes

In this literary criticism , “Construction of the ‘Racial Identity’ by Gaze and Blindness in The Bluest Eye and Native Son”, Md. Abdul Karim Ruman explains how the identity of African Americans are constructed in The Bluest Eye, as well as the racial effect of this construction. Ruman begins by defining some key terms, such as “gaze” and “panopticon”. He looks at ‘gaze’ in the cultural sense, not only defining it as “the desire of one person that constructs the identity of another who is gazed”

images from a places or a things. Let's say an apple is on a stand, you take a picture first from the left side then from the right side. Now that you have two pictures in two different places. If you hold the right one to right eye, and the left one to the left eye in a

In the 17th century, eye movements were studied by direct observations. People were interested in knowing and understanding the motion of eyes while reading, watching, talking, etc. With the advancements in technology in late 20th century, experts used contact lenses and video for tracking and studying the motion of the eyeballs. These studies showed that eyes do not follow a smooth linear path while reading or observing an image instead it is in fixations and saccades. Visual attention is better

Biological Processing System: Understanding Color and Contrast Introduction While interacting with the world, human visual system is perhaps the first and foremost biological process system that directly involves in detecting information. As Colin Ware (2013) noted in Information Visualization, “We acquire more information through vision than through all of the other senses combined”. Hence, it is crucial for information designers to understand influential factors which affect our visual system

During this report the sensory organs will be looked at and how they function. Then the eye will be looked at in more detail and also a disease of the eye known as glaucoma will be discussed and how the condition arises, symptoms shown and treatment available. Sensory organs: The body consist of five major sensory organs they are hearing, smell, touch, taste and sight. Sensory organs are an extension to the nervous system. Sensory organs are a system which consist of sensory cell types and are able

Another theory from Vertov emphasizes the camera eye. He explains how the camera can show the truths of the world better than the human eye. In summary Eisenstein demonstrates his theory of conflict and intellectual montage in October (1928) and The Battleship Potemkin (1925). Plus, both films get the audience to think about life and society. In comparison Vertov displays his theories of movement to create montage and the importance of the camera eye in The Man with the Movie Camera (1929) to illustrate

color, in every corner of the universe. But where does the color come from and why do we see colors? To understand this we need to go way back. Since the beginning of the era colors existed, for example the sky, trees and even us. Maybe the first humans didn’t question this because it was more important surviving and getting food for their families. But as years go by, the people start asking about things, like why the sky is blue or why does the rainbow have a lot of colors. We see colors as an

Laser Treatments for Glaucoma Glaucoma is an eye disease which causes damage to the optic nerve damage. Consequently this damage can lead to progressive vision loss or blindness if left untreated. The human eye is constantly making aqueous humor which provides sustenance to surrounding tissues. Maintaining a fluid balance requires the fluid leaving the eye through the drainage system which is a meshwork along the outside edge of the iris. However, if too much fluid is being produced or if the

Second, they evaluate how the information from each hemifield is represented in the human albino areas. In human albinism the principle deficits occurs at the optic chiasm, where fibres undergo almost complete crossing unlike the normal pattern in which approximately half of the fibres project contralateral to the eye. In order to address the aim, they presented stimuli to the right and left hemifields of an albino viewing monoculaly. Subject, aged
