The Computer Vision Syndrome Essay Example for Free

The Computer Vision Syndrome Essay Close to 150 million people sit in front of a computer monitor each day. Many of them spend more than two hours at a time, focusing on screens as they complete work projects, blog, or just surf the web. If a significant portion of your day involves computer time, you may be at the risk of CVS-Computer Vision Syndrome too. What is Computer Vision Syndrome? According to the American Optometric Association, CVS is a set of symptoms that are all related to working with a computer. These symptoms can affect both the eyes and musculoskeletal parts of the body. Very simply, CVS occurs when an individual overburden the human eye by asking it to perform in prolonged situations that it was not designed to do. Studies have found that the majority of video display workers experience some eye or vision symptoms. A national survey of doctors of optometry found that more than 14% of their patients present with eye or vision-related symptoms resulting from this type of work. The most common symptoms are: †¢ Blurred Vision when looking into the distance †¢ Double Vision †¢ Stinging of the eyes †¢ Excessive tearing of the eyes †¢ Headaches †¢ Neck or shoulder pain. (Keep in the mind that these symptoms are generally experienced after prolonged periods of computer work or, over time, due to progressive eye strain associated with CVS). What Causes CVS? Unlike printed matter, a computer screen displays words and images through the use of pixels which are multi-dimensional and vary in contrast. The eye is always working extra hard to accommodate as it focuses and refocuses on the graded areas of these combined pixels. The eye lens must work harder to support the function of sight. Eventually, the eye tires and becomes lazy. This explains why vision blurs occur and why it is difficult to look away from the monitor and see distant objects clearly. One of the most significant environmental factors affecting work with displays is lighting. Bright lights in the peripheral field of view may cause discomfort glare. An acceptable lighting level may require a compromise between the amount of light needed to enhance VDT screen visibility and reduce reflections and glare and that needed to perform other office reading and work tasks. The brightness of the screen and the surrounding room should be balanced. For dark background screens this often requires using lower light levels. The brightness and contrast should be adjusted to provide balance with room lighting and maximum visibility. Stinging of the eyes and eye irritation can be caused by the dry atmosphere, and starring at the screen. It decreased number of blinking and increased rate of tear evaporation, which effect the dry eyes. The presence of even minor vision problems can often significantly affect the worker comfort and performance. Uncorrected farsightedness, astigmatism, and binocular vision (eye coordination and eye focusing) problems can be major contributing factors to VDT related eye stress. What can I do if I think I might be suffering from eye problems associated with CVS? At first you have to think about limiting the time you spend front of the computer. It is often unaccomplishable, but there are several other methods too: †¢ Seeing an ophthalmologist is a good first step in to determine whether you have a problem like Computer Vision Syndrome. †¢ Eyeglasses or contact lenses prescribed for general use may not be adequate for computer work. Special lens designs, lens power or lens tints or coatings may help to maximize visual abilities and comfort, and helps you minimize eye strain, and get optimal eye performance. †¢ You have to set up your computer’s place properly. The screen must have an optimal height and distance from your eyes. †¢ The colour of screen characters may also affect visibility. The colour of the characters can affect how the eyes focus on the screen. Monochrome, or single colour displays often provide more optimal images for word processing. Dark letters on a light background or invert could generally provide a more readable image than green, yellow-orange, blue or red characters. †¢ You may to set the proper contrast and brightness setting on your monitor too, to make it more viewable.

Essay --

More tragic play The tragedy of Hamlet Prince of Denmark is the most popular works of William Shakespeare. Probably the popularity of this play lies in the use of character of Hamlet in exemplifying the human mind through its complex workings. Hamlet’s internal dilemma of making the decision whether he should revenge the death of his father or not was a crucial turn in his life as the state of mind was the main reason which effected the decision power one makes in his life. His uncle Claudius was the one who murdered his father and the moment when the ghost of Hamlet’s father appears and asks Hamlet as to when the revenge of his foul and most unnatural murder is to take place. From this point onward Hamlet is under a constant dilemma. He does not find himself ready to take the revenge. If Hamlet had killed Claudius at the first opportunity than the revenge would have been taken but his internal dilemma would have never been solved. This play became very popular and the reason for the popularity was Shakespeare’s use of the character Hamlet and through this character he has tried to exemplify the complex workings of human’s mind. Shakespeare used emotion, reason and attitude of Hamlet to allow the readers to form an opinion or make a judgment about the basic aspects of the life of human beings. The reason the prince could not take the revenge of his father’s death was that he was a man of great moral integrity and to take revenge was an act which was against his deepest principals. Some of the other behaviors of the prince was that after the death of his father Hamlet became so disenchanted with his life that he lost all his desire and will to take any kind of revenge. Due to the delay in revenge Shakespeare was able to develop th... ...a proper burial for her brother and in ‘Oedipus the King’ son has killed his father and married his mother while Glass Menagerie is the only play which is giving us the picture of real life and this the reason that I have chosen this play as my favorite. This play is more tragic of the above plays as it is a tragedy emerging from real life. The condition of the apartment shown in the play is very much common in the country. In poor countries even worse apartments are found. In the play all the characters are going through a frustration and no one is happy from his present state of mind. The wife is lonely as her husband has left the home. The son and daughter are not satisfied as the son is planning to escape and the daughter is playing the records over and over again to show her frustration. This play is a true tragedy found in the richest country of the world.

America Before and After Revolution

The way of life in the colonies before the Revolution was far more different than the way of life after the war. The colonies were completely run by Britain and didn't have to fend for their own needs. Trading, taxing, and other parts of the economy were run by the mother-country. However, during the Revolutionary War, idealists like Thomas Paine produced concepts that fruited the idea for a more republican society. These new beliefs were reflected in the Declaration of Independence, after the war it played a huge part in the Articles of Confederation, and it was later the ideas established in the American Constitution. In the years before the Revolution, the colonies were still growing. The New World was a melting pot for different European cultures and social status played a huge part in how people viewed each other. Even though the colonists left Britain to escape social structure, they found themselves once again ranking people by how educated they were or how much money or land they had. The landowners were better off than the widowed, the poor and the indentured servants. But it was possible for citizens to earn their way into a higher class. Much like after the Revolution, the slaves had no worth and were at the bottom of the pyramid. Education was only offered for men to prepare them for ministry and it taught them the dead language of Latin that was important for interpreting the Bible’s scriptures. The link to religion was prominent in politics as well. A majority of the colonies were run by Parliament appointed officials that had close ties to the established churches of the colonies. The early years of the colonies were revolved around religion and were greatly affected by how England ran their government. England’s hierarchical society was all that the colonist knew and it wouldn’t be for a hundred years before they would find new ways to establish the colonies. Trading in the colonies was heavily intertwined with Britain. No trading with other countries was permitted unless it went through England’s ports first. The  British Empire  used them as a source of raw resources and as a source of taxes to pay for  Britain's many wars and ventures. However, agriculture, fishing, lumbering and other industries had a large impact on the development of the Americas. It was the first time that the colonies were producing things by themselves and providing their own goods helped instill confidence in the colonists. The American Revolution forever changed the colonies. The colonies were now a loosely united group of states, called the United States of America, and colonists now considered themselves American instead of English. The common man was given more rights and control. Laws like primogeniture were abolished and people were able to tend to their affairs freely. The institution of slavery was weakened and some Northern states even abolished it. After the American Revolution, America was free to industrialize and sell goods to other countries at more favorable prices, no longer being locked into an unfair trading monopoly with the British. Industry and manufacturing increased because of the high demand from other countries, thus broadening their amount of trade. Financial wizards like Alexander Hamilton led the States into what would be one of the most economically dominant countries of the world.
