optic nerve, which carries visual information from the eye to the brain, becomes inflamed. Most of the damage is done to the protective myelin sheath that surrounds the nerve, which is vital for good vision. A few symptoms that occur to people who have Optic Neuritis are: distorted color vision, blurriness, pain, and even vision loss. During a routine eye exam, a doctor will look for signs of Optic Neuritis by checking the eye pressure. The eye will be measured and the pupils will be dilated in…

Video Games and How They Affect our Biology In the past, there have been many debates on video games and whether or not the effects they can have are beneficial or harmful. Most people would tell you that it is the latter; however, newer research and studies suggest that video games present many more advantages than what one would expect. They have been proven to be of use in aiding those with mental disabilities as well as providing an alternative means of exploration for people with physical…

Vision can change temporarily or permanently due to eye problems that can provide information in a patient’s health status as well as problems with self-care. Changes in the structural components of the eye caused by aging begin early especially with the lens of the eye. Visual functions are reduced due to age-related changes of the nervous system and in the eye support structures. Three layers form the wall of the eye: sclera, choroid, and retina. The sclera, a thick, white, outermost layer…

olfactory nerve serves the sense of olfaction or smell, Test is done with the use of non-noxious aromatic substances and check if able to smell and identify and mark if any abnormality noted. Optic Nerve (CN II): This is a purely sensory nerve, test each eye for visual acuity, visual fields, and fundoscopy. Test visual acuity: Snellen chart for distant vision, newspaper for near vision. Visual fields: Visual fields done by confrontation test. The…

viewing, as the eyes are most comfortable switching between various focal distances and light complexities. Chris’ eyes will be under extreme strain due to her age and slowly degrading eye functionality, as well as the constant use of a digital screen. The pressure on the eye from an iPad screen is due to the screens fixated distance, which is not encouraging the activity of the eye. Two sets of muscles work in synergy to establish an adequate focus on objects, the first set converges the eyes…

Most made no sense to her, though the eye one did. In her studies, the image of a glowing eye was clearly a reference to a clairvoyant. But what was she supposed to do with this? She stepped into the doorway of Melinda’s quarters, and found her sitting at an ancient ornate writing desk, staring out the window. The Headmistress…

in the world," he smiled widely, letting his worries drift away from him and simply indulging in their embrace. He was so happy that Amaimon was happy, that he held him and for the most part he no longer looked so sad. He smiled gently, closing his eyes as he yawned, resting his head on Amaimon's shoulder "It's already is better, just getting to hold you makes it so much better. Just getting to kiss you makes it better. Just getting to tell you I love you instead of writing on your hand makes it…

illusions are usually described as visual images that differ from reality. The eyes and brain “sees” something that does not really match the physical measurement of the image. Optical illusions can function in many ways, they can be images that are different from the objects that make them up, they can also be ones that come from the effects on the eyes and brain through excessive stimulation, and others where the eye and brain creates unconscious inferences. For my science fair project I will…

Refraction In physics, "refraction" is the mechanism that bends the path of light through the eye. Refractive error is an optical abnormality in which the shape of the eye fails to bring light into sharp focus on the retina, resulting in blurred or distorted vision. Examples of refractive error are myopia, hyperopia, and astigmatism. In optometry, a "refraction" procedure is the measurement of refractive error by an eye care professional, usually for the purpose of correcting the error with…

Alice Walker is a African American women, growing up in a segregated America and the civil rights movement showed her first hand how awful some people can be. And before all the anger, she may have felt lost in a world that rooted against her. Equally important, the title of this short story is “Am I Blue?”, as if the speaker, Alice Walker, is asking…
