save your eye from COMPUTERS
Over 175 million Americans use a computer either on the job orat home. Nearly 75% of these people report vision problems asa result of their computer use.Are you one them?Dry and irritated eyes, difficulty focusing, headaches, backaches,neck strain, and double vision are just a few of the symptomscaused by computer use.Collectively, these symptoms are known as "Computer VisionSyndrome," which the American Optometric Association (AOA)defines as being "related to near work - experienced duringcomputer use."You might recognize that phrase "near work" from an earlierlesson. Computer use causes near-point stress-reported bythe AOA as one of the leading causes of nearsightednessand its progression.How does the computer hurt your eyes?Human eyes were not made to look at a computer screen. The screenyou are viewing right now is actually made up of thousands ofpixels. Pixels are, essentially, colored dots that make up theimage you see or the text you read. The more pixels on your screenfor a given image, the clearer the image will appear.But your eyes cannot focus directly on each of these thousands ofpixels. Instead, you have to focus over and over to keep theimages sharp-which causes strain and tension in your eyes.Computer screens have also been shown to reduce blink rates byup to five times! This is why your eyes feel dry and irritatedafter staring at the screen.Think of blinking like breathing: you can't do without it. Reducedblinking could be said to be the asthma of the eyes.So, short of quitting your job, what can you do about ComputerVision Syndrome?In the long term, following the Rebuild Your Vision program will helpyou combat the deterioration caused by the near-point stress of
computer use.And in the short term, here are some tips your eyes willappreciate.--Essential Tip #1: Monitor Your MonitorRepositioning your monitor is an easy and effective way to avoidawkward head or eye movements. It should be squarely in front ofyou at a distance of 18 to 28 inches, with the top of the monitor(not the screen) level with your eyes.You may also have to adjust the angle of your monitor to allowyour eyes to remain in a natural position (straight ahead andslightly down).--Essential Tip #2: Glare CareModifying your office lighting will eliminate glare and harshreflections. First, find the source of the glare: is it comingfrom a window, task light, or the computer screen itself?Adjust blinds or curtains to minimize sunlight. Turn downoverhead lights so that the brightness of the screen and thesurrounding room are balanced. Task lights should be positionedto provide direct light for reading and other office work butshould not shine directly on the computer.--Essential Tip #3: Take a Break-the "10-10-10" RuleIt's easy to lose track of time at the computer. So you need tolearn how to take a break. Here's how:Every time you are performing close vision work for over 10consecutive minutes, look up and focus on anything that isat least 10 feet away, for at least 10 seconds.The best way to incorporate the 10-10-10 rule while at yourcomputer is by using our Vision Defense Software, includedas a bonus with the Rebuild Your Vision Program.This simple rule helps to prevent the damaging effects ofnear-point stress and could literally save your eyesight! (And acomputer break is a perfect excuse to perform your Rebuild YourVision eye exercises.)--Essential Tip #4: Some Folks Have Special Needs
Seniors should take extra care arranging their work stations. TheAOA notes that workers over 50 years of age require twice thelight levels of younger adults for comfortable work.By the same token, very often small children share the samecomputer as their parents, a situation that can lead to injury,as monitor distance and position have been set up to accommodatethe adults.To your vision -- for life,

There was a controlled study conducted on a group of Inuitfamilies in Barrow, Alaska, years ago by a very respected groupof eye doctors. It evaluated the relation between genetics andthe environment in bad vision.It was an ideal setting in that parents and grandparents hadlittle or no formal education, while children regularly attendedpublic school.The study results showed that the uneducated parents andgrandparents had little or no form of myopia (nearsightedness),while nearly 58% of the children attending school were diagnosedas myopic.A genetic malfunction increase of 58% over one generation wouldbe impossible. The researchers came to the conclusion that thestress put upon the eyes while performing continuous near-pointwork in the classroom was causing myopia among the children. --Young et al. 1969. American Journal of Optometry and Archives of American Academy of OptometrySo what causes nearsightedness if it's not genetic? Science hasalso answered this question.It's a condition called near-point stress. Near-point stress iswhat your eyes experience when you focus on anything close toyou: computers, books, television, etc.Focusing up close is not natural to your eyes. Your eyes arein a relaxed state when they are looking at a distance andfocusing up close puts a stress on them.The American Optometric Association identifies "near-point stress"as being one of the leading causes of nearsightedness and itsprogression.I find this amazing, considering many doctors willstill tell you that nearsightedness is solely a geneticcondition.It just doesn't add up.*How have thousands of people improved their vision naturally if
bad vision is a genetic problem?*Why is near-point stress defined as a leading cause of nearsightedness if nearsightedness is a genetic condition?The fact is, the data is in, and times and beliefs are changing.There are many eye doctors that now support eye exercises andtheir role in natural vision improvement.To your vision - for life,Orlin SorensenCopyright Rebuild Your Vision 2008.All Rights Reserved.http://www.rebuildyourvision.com/13About The AuthorOrlin Sorensen is a former commercial airline pilot and the creator of the best selling Rebuild Your Vision Program.

20/20 vision
Herman Snellen, a Dutch ophthalmologist, designed the first eyechart, which measures visual acuity. Referred to as the SnellenChart, it was developed in 1862 and is still used today.He set the baseline of measurement at 20 feet, the approximatedistance at which light rays entering the eye are paralleland do not require our eyes to bend the rays to focus themupon the retina.Snellen set the standard of 20/20 vision to represent "normalsight," or what a person with normal vision could see at adistance of 20 feet.This means that a person with 20/40 vision must be 20 feet awayto read what he or she should be able to read at 40 feet; aperson with 20/85 vision must be 20 feet away to read what heor she should be able to read at 85 feet away, and so on.This standard does not measure visual acuity at close distances.Similar charts were devised with smaller letters to read atclose range for the measurement of near vision.A Snellen Chart is included in the Rebuild Your Vision programso you can measure your vision as it improves. I've alsoincluded a log for you to record your daily progress.To your vision - for life.
