It happens because your eyes follow the same path over and over. And it can get worse the longer you continue the movement. When you work at a computer, your eyes have to focus and refocus all the time. They move back and forth as you read. You may have to look down at papers and then back up to type. Your eyes react to changing images on the screen to create so your brain can process what you’re seeing. All these jobs require a lot of effort from your eye muscles. And to make things worse, unlike a book or piece of paper, the screen adds contrast, flicker, and glare.
You’re more likely to have problems if you already have eye trouble, if you need glasses but don't have them, or if you wear the wrong prescription for computer use.
Computer work gets harder as you age and the lenses in your eyes becomes less flexible. Somewhere around age 40, your ability to focus on near and far objects will start to go away. Your eye doctor will call this condition presbyopia.
Answer:The 2009-M57-Patents scenario tracks the first four weeks of corporate history of the M57 Patents company. The company started operation on Friday, November 13th, 2009, and ceased operation on Saturday, December 12, 2009. As might be imagined in the business of outsourced patent searching, lots of other activities were going on at M57-Patents.
Two ways of working the scenario are as a disk forensics exercise (students are provided with disk images of all the systems as they were on the last day) and as a network forensics exercise (students are provided with all of the packets in and out of the corporate network). The scenario data can also be used to support computer forensics research, as the hard drive of each computer and each computer’s memory were imaged every day.
