Computer Vision Syndrome (CVS)

              Computer vision syndrome (CVS) is a very real problem for many people who spend hours daily in front of a computer screen.

             Sometimes, simply rearranging your work environment to create better ergonomics is all you may need to do to reduce eye strain and other vision problems related to CVS. In some cases, a good pair of computer eyeglasses may help you see better at just the right distance range needed for viewing a computer screen.

Computer Eye Strain: 10 Steps for Relief 

            How to find a computer vision specialist, minimize glare, adjust your monitor, and cope with symptoms such as eye strain, eye fatigue, dry eyes, light sensitivity, blurred vision, headaches and more.

HP Pavilion P6120F Desktop PC

                              Desktop computers offer more power for the money than almost any laptop or notebook computer. The HP Pavilion P6120F is not exception. Although the popularity of desktop computers is dropping against stylish little net books and well-priced portable computer they remain the staple of business and enthusiasts for good reason.

              Although not the sexiest, for any computer that does not need to be moved around, desktop computers are the best option. This HP Pavilion, Windows-based desktop computer can be matched with a large screen monitor for a powerful desktop computer under $1000.

Here's a quick rundown of the specifications:

• 2.80GHz Intel Pentium E6300 processor
• 8GB of memory
• 1TB (1000GB) hard drive
• 1 x PCIex16 slot
• 5.1 channel audio
• LAN
• Wifi
• DVD burner

               The HP delivers a feature-rich package with a CPU known for its over clocking abilities. The E6300 is a an entry-level processor which is based on the same technology as its older brothers. Because of this, the processor can safely be over clocked, meaning have its speed increased, by 25% without any additional fancy technology or hardware trickery. This makes it quite worth it for a little bit of time spent increasing the front side bus speed from 266MHz to 333MHz.

                The system also comes with 8GB of memory. That is pretty huge. Seeing as the computer is intended for home use, that amount of memory is more than anything you can possibly throw at it.

                 The mix of networking options if pretty standard, except that it also includes Wifi connectivity. Although Wifi has been standard fair on laptop computers for a very long time now, their absence on desktop computers usually means that the desktop has to be within cable distance from the home router. Well, with that limitation removed, this computer can be placed a room or two away from where the router sits. The router can be placed in a central location in the home and the computers placed where needed. 300MB/s wireless is supported.

             A DVD burner is included as standard, as it is on almost any modern computer. It supports Lightscribe so the cover side of supported DVDs can have a picture burned onto it by the DVD player.

              Storage needs are met with a large terabyte hard drive. A terabyte is 1000GB, which is about the size of 150 DVD movies. Plenty of space for almost anything and the speed should do fine for most applications.

              Graphics is supported through onboard graphics. This is limiting in that most new games cannot be played, but a good graphics card can cost as much as this whole computer, so this limitation is expected. The processor is not fast enough for modern games though, so adding a super-fast PCIe x16 video card will not turn this into a superb gaming machine, although it will handle the needs of the non-fanatic.

Can computer use cause eye strain?

 

             The following are the most common symptoms of eye strain, which may be attributed to prolonged computer screen viewing. However, each individual may experience symptoms differently. Symptoms may include:

· red, watery, irritated eyes

· tired, aching, or heavy eyelids

· problems with focusing

· muscle spasms of the eye or eye lid

· headache

· backache

           Symptoms of eye strain are often relieved by resting the eyes, changing the work environment, and/or wearing the proper glasses. The symptoms of eye strain may resemble other eye conditions. Always consult your adolescent's physician for a diagnosis.

How can my child avoid eyestrain?

                  The Occupational Safety and Health Administration (OSHA) has provided the following helpful suggestions for making the appropriate workstation modifications to help avoid eye strain:

§ Position the video display terminal (VDT) slightly further away than where you normally hold reading material.

§ Position the top of the VDT screen at or slightly below eye level.

§ Place all reference material as close to the screen as possible to minimize head and eye movements and focusing changes.

§ Minimize lighting reflections and glare.

§ Keep the VDT screen clean and dust-free.

§ Schedule periodic rest breaks to avoid eye fatigue.

§ Keep the eyes lubricated (by blinking) to prevent them from drying out.

§ Keep the VDT screen in proper focus.

§ Consult your adolescent's ophthalmologist, as some individuals who normally do not need glasses may need corrective lenses for computer work.

Reducing Your youngster's Risk of Computer Vision Syndrome and Ergonomics Problems

            To reduce your youngster's risk of childhood computer vision syndrome and computer ergonomics problems, make sure he or she is seated comfortably and has a "neutral" posture when working at the computer. Characteristics of this posture include:

• Head is balanced on neck, not tilted back or forward. Computer screen should be positioned approximately 15 degrees below eye level.

• Back is straight and shoulders back but relaxed. Avoid slumping forward over the keyboard.
• Upper arms are close to the body and relaxed, not angled away from his sides or tilted forward.
• Forearms are flat on the desk, with the elbows forming at least a 90-degree angle.
• Hands are nearly level with forearm, with little wrist bend.
• Feet are flat on the floor or a footrest, with knees forming at least a 90-degree angle. (The angle behind the knee should be open; don't tuck legs under the chair.)

            Many experts also recommend getting away from the computer every 20 to 30 minutes to stand and stretch. This helps relieve muscle tension that can contribute to computer vision problems and computer ergonomics problems.

Tips for Monitoring Computer Use by Young Children

 

                  The National Association for the Education of Young Children (NAEYC) is an organization that sets standards of excellence for programs designed for children from birth through age 8. The organization bases these standards on current research in child development and on the professional opinions of early childhood educators.

              NAEYC has issued the following specific recommendations regarding computer use by young children. In addition to helping your child have the best educational experience when working on a computer, these strategies also may decrease your young child's risk of fatigue-related eye strain, computer vision syndrome and computer ergonomics problems:

• Computers should supplement, not replace, educational activities such as art, books, music, outdoor exploration, dramatic play and socializing with other children.

• Parents should guide children's use of computers. Be on hand to help your child, answer questions and interact with him as he works on the computer.
• Take the time to observe your child at the computer and participate in computer activities with him. Observing children working at a computer can reveal a lot about the way they think and solve problems.
• Encourage your child to work with a sibling or friend at the computer whenever possible. Using computers with others encourages important social skills, such as turn-taking and cooperation, and helps build your child's ability to speak and listen.
• Learn more about software for young children, and carefully preview the software your child uses. While many high-quality products are available, some software is not appropriate for young children because it is difficult to use, highlights violent themes or does not foster language or learning.

Computer Risks for Children

 

            Kids and computers are nearly inseparable these days. With many school-age kids and even preschool children spending hours in front of a computer every day, it's worth considering what effects computers might have on your children's eyes and their vision. Is it bad for their eyes? Does it help or hurt school performance? Should kids wear computer glasses at school?

         These and other questions about kids, computers and computer vision are common. This article will help you learn more about these timely topics.

Computer ergonomics is the study of people's efficiency at their computer work stations. Problems with computer ergonomics are closely associated with computer vision syndrome (CVS), which can affect children as well as adults.

             But too much of anything can be a problem. Like adults, children who spend many hours in front of a computer have a greater risk of developing computer ergonomics problems and computer vision syndrome. And many eye care practitioners who specialize in children's vision believe prolonged computer use among children puts them at risk for progressive myopia.

            For these reasons, it's a good idea to set guidelines for your children when it comes to the amount of time they spend in front of a computer.

            Too much unsupervised computer work may cause vision problems for kids.

Tips for controlling your child's computer use

•   A good tool a child has for screening material found on the Internet is his or her brain. Teach children about exploitation, pornography, hate literature, excessive violence, and other issues that concern you so they know how to respond when they see this material.

• Examine your own online habits. Do you have trouble controlling your Internet use? Remember, you are your child's most important role model.

• Don't ban the Internet. It's an important part of most kids' social lives. Instead, establish family Internet rules about where your kids can go online and what they can do there - and stick to them. These rules might include: a limited amount of time online each day; no surfing or instant messaging until kids complete their homework; no chat rooms or online adult content. Children, being children, may struggle to keep to such verbal agreements, in which is it is essential to use software to keep control of how your child uses the computer (see below).

• Keep the computer out in the open. Set up your computer in a public area of your house, not in a child's bedroom.

• Suggest alternatives. If your children seem interested only in playing online video games, try an offline tie-in to one of their favorite games. For example, if your child enjoys fantasy role-playing games, encourage her or him to read fantasy books.

• Make use of the commercially available Internet filtering and parental control software programs. These programs are vital in the vast majority of cases in which children are unlikely to regularly stick to verbal agreements about computer and Internet use. Such software packages can, for example, block sites by name, search for unacceptable words and block access to sites containing those words, block entire categories of material, and prevent children from giving out personal information.

• Use these same packages to monitor your children when they're online and monitor the time they spend online.

Control child's computer use

             Nowadays children spend a great deal of their childhood playing on the computer and surfing the web. This can be a great source of frustration for many parents. Initially, parents welcomed the Internet into their homes, believing it would provide their children with access to a bottomless pit of beneficial and educational information. However, many parents soon realized that, instead of using the Internet for homework or research; for the purpose that it was originally meant for, that their kids were spending hours surfing inappropriate and undesirable websites, instant messaging with friends, playing online games, or talking to strangers in chat rooms.

            For many years it has been a challenge for parents to maintain a healthy balance between the amount of time their children spend being entertained by media outlets, and the more traditional, often outdoor activities that have kept children happy for generations.

Reducing the Risk of Myopia Linked to Computer Use

                  Though heredity seems to play a significant role in the development of myopia in childhood, some research suggests that eye strain, and specifically computer eye strain, may also be involved.

                    To see clearly up close, the eye has to exert focusing effort. Some researchers feel that fatigue caused by excessive focusing can lead to changes within the eye that cause myopia. And experts agree that focusing on images on a computer screen causes greater eye fatigue than reading normal print in a book or magazine.

                   To reduce the risk of focusing fatigue that can cause advancing nearsightedness among kids who spend a lot of time on a computer, many eye doctors recommend frequent breaks from computer work. Some call this the "20-20-10" rule: Every 20 minutes your child should take his eyes off the computer and look at an object at least 20 feet away for at least 10 seconds.

                   This simple exercise relaxes the focusing muscle inside the eye and may help reduce eye strain and eye fatigue that could cause progressive myopia. Some eye doctors also recommend special computer glasses to help relieve eye strain.

Preparing Your Child for Using Computers at School

                    To make sure your kids are ready for computer use at school, schedule a comprehensive eye exam for them prior to the start of every school year. This exam should include tests that evaluate near vision skills for computer use and reading as well as visual acuity testing that is conducted both across the room and up close.

                  Tell your eye doctor if your child has shown any signs of eye or vision problems, such as squinting, frequent eye rubbing, red eyes, head turns and other unusual postures, or if he or she complains of blurred vision or eye fatigue when reading or using a computer. Avoidance of computer work may also indicate vision problems.

                  Computers are an important (and virtually unavoidable) part of your child's life and education. A comprehensive eye exam each year during the school years can help him be as comfortable as possible and perform at his best during computer work. In some cases, a referral to a children's vision specialist and/or a program of vision therapy may be indicated to resolve computer- or learning-related vision problems.

Intel Core2 Extreme QX9650 3.0GHz Processor with 12MB Cache

                   The Intel Core2 Extreme quad-core CPU offers the best in computer performance today. Four cores will carry you four times as far, and you sure have to pay for this level of performance.

                At the end of the Pentium 4's era, there was an AMD vs Intel battle to speed up processors to extreme levels. When processors became hot enough to cook on, there was obviously something that had gone wrong. Intel was quick to release a dual core Pentium, and then its Core2 range. The Core2's managed to bring power consumption back to sane levels and regain much of Intel's street cred.

             After dual-core, the obvious next step is quad-core. As the technologies to produce the internals of a CPU get more sophisticated, so more cores can be stuffed into a single processor. But is there a tradeoff?

              Intel Core2 Extreme offer a huge performance leap over their smaller brothers and sisters. By definition, the Extreme series leave the bus and multiplier so they can be adjusted by the user. This is useful for those who like to over clock, but not for the vast majority of desktop computer users who just want things to work.

            This processor offers a large 12MB L2 cache, which amounts to 3MB per core. This is an increase of 50% of what is found in the other dual and quad-core processors in the range. This is a real performance booster, as L2 cache allows information to be stored close to the processing core, for much faster operations on data.

            A new motherboard will be necessary, look for one that supports DDR3, to really stay ahead.

             When building a super-fast computer for gaming or heavy duty office work with processor intensive programs, this is a processor worth considering. Stay ahead of the curve, but pick something else from the range if you want value for money.
