Why You Get Eyestrain and the Need for Computer Glasses

Computer eyestrain is the number one office-related health complaint in the U.S., with some 60 million Americans suffering from computer eyestrain according to the American Optometric Association. Computer use at work and home continues to grow exponentially. Computer use is associated with a number of visual and physical symptoms experienced by 50%-90% of all computer users. So, if you have experienced fatigue, headache, eye strain, blurred vision, dry or irritated eyes and neck or back aches at the computer it is possible that you are suffering just some of the symptoms called Computer Vision Syndrome (CVS). Solving the symptoms of CVS requires a visit to your eye doctor to determine if you need corrective lenses while working at the computer, especially if your computer use is two or more hours a day. The reason for computer vision related problems is further explained with a simplified description of how the eye and brain processes visual information.

Working at a computer is more visually demanding than doing other standard office work such as reading printed documents. Human vision is not designed for staring into a computer screen. Your eyes require constant sharp edged images like the characters found on ink and paper to process and focus on comfortably. The eye system of lens focusing is referred to as accommodation. Computer images are made up of tiny round dots, known as pixels. Since your eye cannot focus on the tiny round pixels, you must constantly refocus or accommodate to keep the images sharp. The eyes can’t keep a constant relaxed focus on the computer screen, even when you increased the number of pixels per square or max out the computer’s refresh rate. The monitor is constantly being “redrawn”, and this eventually leads to repetitive stress of the eye muscles and fatigue.

Bifocals are not helpful at the computer. In fact, the bifocal only increases the problem since the reading portion of the bifocal is designed for a shorter distance than a computer screen and for a much lower visual angle. The tendency to lift the chin up and move closer to the screen just leads to lower back and neck problems. Progressive lenses (eyeglasses without bifocal lines) have the same shortfalls since the area for intermediate computer vision is found in the lower half of the glasses and the area for viewing is limited.

If you spend two or more hours working at the computer CVS can be a real problem at home or in the workplace. Savvy employers are beginning to recognize that increase work production can be realized with eyewear designed for computer use. Visit your eye doctor who is ready to help you eliminate the problems of Computer Vision Syndrome with a dedicated pair of computer glasses. You can benefit from a natural head and neck position with computer glasses or the new ergonomically designed clip-on computer reading glasses.

You can choose to have a dedicated pair of computer glasses custom made or you may be wondering how to convert your existing general purpose pair of eyeglasses that you use for distance and reading only into computer glasses. Well, there is an easy and affordable way by using a new innovative clip-on lens to view a computer monitor. Simply clipping the lens on to the bridge portion of your general wear eyeglasses that you are already wearing, and you can immediately feel and see the difference while working on a computer. Save your eyes from nagging eyestrain and improve your ability to be productive in the workplace as well. A pair of dedicated computer glasses or the new clip-on computer reading glass will do much for you in all aspects of work, as well as and make you a feel better outside of work since they will eliminate much of the eyestrain, lower back discomfort and neck pains that you are experiencing.

Learn Why Clip-On Computer Reading Glasses

Comparing the new Computer Conversion Clips, to several other clip-on computer reading glasses offered on internet discount sites, have resulted in findings that show significant optical and structural differences among the clips. These differences can dramatically affect the computer user both negatively and positively. You can learn to get more value for your dollar with the following information. The clip-on computer reading glasses were compared by design advantages such as size, shape, weight, and optical lens quality to allow for the best computer user experience. It was an easy comparison to make with the computer conversion clips design advantages providing the best choice to reduce, eye fatigue, eyestrain and increased physical comfort from neck and shoulder pain. What are clip-on computer reading glasses?

A clip-on computer reading glass provides additional magnification to be attached over the upper portion of the wearer’s eyeglasses, converting the distance prescription of general wear bifocals or progressive lenses to mid-range computer distance; this will allow the wearer to see a computer monitor clearly in the intermediate ranges between 18 to 30 inches more comfortably. The wearer will then be able to view intermediate distances, such as the computer screen, while maintaining a normal head position. This would eliminate having to elevate the chin while moving closer to the computer screen to see what is on the monitor more clearly while lifting the chin up to see through the bifocal portion of their glasses. Ideally, the clip-on should only cover the top part of the eyeglasses to allow the wearer to continue to use the lower reading portion of their eyeglasses to see near.

Eye Care Professionals, and even Chiropractors, are the chief means of providing these newly designed Computer Conversion Clips to the public. You won’t find the new clip-on’s at the local internet discount sites. The many design advantages of CCC’s makes the small cost difference a bargain. Eye care professionals and chiropractors alike understand and trust the digital design advantages of the CCC’s for their bifocal age patients who show signs of eyestrain or neck problems while working at the computer with general wear glasses for 2 or more hours a day. Computer users buy clip-on computer reading glasses because of convenience and cost savings.

The general cost of a dedicated pair of computer glasses will range from $175 – $350. The cost and quality of the eyeglass frames and lens types used for a intermediate computer focus and near vision accounts for the wide range in costs. Buying a computer reading type clip-on at your local internet site to clip to your general wear glasses for about $20, sounds like a great deal… until you learn about the design differences with the new Computer Conversion Clips. It is good to remember that most of the neural input that comes into our body is from our eyes, so vision is one sense that you should value. Here are some of the valued differences in Computer Conversion Clips verses the other clip-on computer reading glasses you can find on discount internet sites.

Quality Lens Materials: All the usual brands of clip-on’s sold on the internet are made of a polycarbonate material. Polycarbonate is lightweight and strong, but also scratches easier than most other plastics. Polycarbonate material also tends to yellow with age and UV exposure. About 10% of the eyewear population discovered seeing through polycarbonate material more difficult than seeing through other lens materials.

CCC’s are made of an acrylic material that is more scratch resistant than polycarbonate, and acrylic transmits more light through the lens medium than polycarbonate to the back of the eye. Motor cycle shields are made from this material as well as windows on submarines. Digital design optics with the acrylic material gives you high visual performance across the entire area of the lenses.

Anti-fatigue Designed Optics: All the usual brands of clip-on’s sold on the internet have a very wide spacing for the optical centers of the clip-on lens. This makes it harder for the eye muscles to maintain a comfortable focus on the computer screen for long periods of time. The eyes are forced to compensate for the wide optical centering by turning in, commonly called converging, a greater amount than usual to maintain stereopsis and reduce the possibility of any possible double vision.

CCC’s are designed by eye professionals to eliminate the extra work on your eye muscles that have to turn in or converge in more than normal when viewing a computer monitor. This attention to preferred optical centering, so the eye muscles don’t overwork, helps to minimize any unwanted eyestrain and eye muscle fatigue.

Non-glare Anti-reflection Coating: All the usual brands of clip-on’s sold on the internet usually don’t apply a mulit-layered coating process to eliminate glare and reflections on the lenses. This is a more costly process, and would be reflected in the cost to the consumer.

CCC’s come with a non-glare anti-reflection coating to reduce headaches from excessive glare and reflection. The anti-reflection coating improves vision with the resulting increase of light transmission traveling through the lens to the back of the eye. All of us that are bifocal age need more light, and this non-glare anti-reflection coating will increase light to the back of the eye by another 8 to 10%!

What Is Computer Speed Memory?

Increase Computer Speed Memory by Increasing the Ram (Memory)

Did you know that if you increase the memory on your computer, you can increase the speed? When you try to open a program on your computer, it needs to load itself from the hard drive into the memory. If the memory resources are low because there are too many programs open at the same time, or you have too many programs on your computer, this all takes memory to make things happen. The result will be a computer that runs very slow.

Nobody likes working with a computer that is slow. To have a computer that performs with speed, making the action process happen in 2-5 seconds, it is important to have ample RAM (memory) installed on your computer for computer speed memory. Many of the older computers might have 1 Gigabyte of memory if they are lucky, usually less. This is way too low by today’s standards. You should have a minimum of 5-6 Gigabytes of RAM and preferably 8-10 Gigabytes if you can afford it.

Each action performed, every program installed, takes up and uses computer memory. Don’t overload your computer. You can combat that by increasing the memory (RAM). Freeware contributes to a slow computer because it quite often comes bundled with other freeware that is installed on your computer. Many of those programs are just using up memory and are never used.

Tips for Computer Speed Memory Performance

There are several tips you should be aware of for computer speed memory to keep your computer running at maximum speed. Having the proper security programs on your computer is a must. If you try to shortchange yourself and your computer by not installing these mandatory programs just to save some money, you will ultimately pay the price down the road.

Security programs guard your computer against viruses such as worms, Trojan horses, adware, spyware, malware and other damaging viruses (just to name a few), to your PC. Use the best antivirus software, and keep it updated by version and daily updates. There is a constant new supply of viruses that attack your computer on a daily basis. Keeping all your programs updated, especially your security programs, should keep your computer protected.

When checking for the best antivirus programs, be sure and check all the problem areas listed on the landing page of the product, what the product protects, customer testimonials, product reviews, customer service, and a 30 day trial period with a full money back guarantee.

Ways to Speedup Computer Speed Memory

Run disk defragmentation.

Run disk cleanup.

Go to start all programs, click on accessories, system tools, and select disk defragmentation, and then run disk cleanup.

Uninstall programs that are no longer being used.

Click on start, control panel, uninstall programs, select and highlight program you want uninstalled, click on uninstall, when program is completely uninstalled, close out of the control panel and restart your computer to complete the uninstall.

Summary for Computer Speed Memory

Make sure you have plenty of RAM (Memory), preferable a minimum of 5-6 Gigabytes. If you can afford 8-10 Gigabytes this would be even better.

Using a good registry cleaner is the key to good performance

Use only the best antivirus software

To keep your computer safe, use good adware and spyware software programs

Also use a good Malware Program

Normally there is no – one program – that will deliver all the goods to keep your computer safe.

Keep your computer programs, driver devices, and all software updated at all times and make sure your computer is set for automatic updates from Windows Update.

Uninstall all the programs you no longer need or use on your computer.

Cloud Computing – Is It Safe?

There are essentially two kinds of computing environments:

On-premises computing is the traditional form of computing in which you or your company own and manage your own systems. All the applications you use, as well as your data files, are in your own computers on your own premises either on individual PCs or on an in-house local area network.

In cloud computing, by contrast, your applications and files are held remotely on the Internet (in cyberspace) in a network of servers which is operated by a third party. You access applications and work on your files from your PC simply by logging on to the network.

Cloud services are provided by cloud-hosting providers, companies such as Google, Amazon, Oracle Cloud, Rackspace, Microsoft Azure, and so on.

There is nothing fundamentally new about the concept of cloud services. If you are using Gmail, Hotmail or yahoo for your emails, you are using cloud services and probably have been for years.

What is relatively new is the types of services that are being offered in a cloud-environment. These now go far beyond email to cover all the IT services that an on-premises computing environment would deliver, such as accounting, marketing, human resources and so on.

Advantages of cloud computing

Cloud computing has several advantages over on-premises computing:

1) You can run an application or access your files from anywhere in the world using any computer.

2) Cloud computing is cheaper.

3) You need less technical knowledge.

4) Cloud computing delivers a better performance.

5) Cloud computing is eminently scalable. Increasing the number of applications you use or the amount of data you store does not require a heavy investment; you only need to advise the cloud-hosting adviser.

Given these advantages it no surprise that over the last few years there has been a widespread rapid adoption of cloud computing. Analysts estimate that the growth rate of all spending on cloud IT will soon be at least four times faster than the growth rate of all spending on on-premises computing.

Indeed, analysts are expecting the annual growth rate of spending on cloud computing to average 23.5% compound from now until 2017. In addition, by that year spending on cloud services will probably account for one-sixth of all spending on IT products, such as applications, system infrastructure software, and basic storage.

Given the rapid growth in cloud computing, the big question, of course, is whether cloud computing is safe. Is it more or less safe than on-premises computing?

The short answer is that cloud computing is not less safe than on-premises computing. However, the threats are somewhat different in nature, though they are converging.

Threats

Generally speaking, there are six major threats to computer security. These are:

Malware – is malicious software such as viruses, trojans, worms, spyware and zombies. Malware is installed on either a PC in your home-office or a cloud-computing server. Where malware gives control of a network of computers to a malicious group (eg, to send spam) it is called a botnet.

Web app attack – is an attack in which web-based applications are targeted. It is one of the most common forms of attack on the Internet.

Brute force attack – works by trying all possible combinations of letters or numbers in order to discover a cipher or secret key. For example, you could crack a password by repeatedly trying to guess it. Modern computing power and speed makes brute force a viable form of attack.

Recon – is reconnaissance activity that is used to choose victims that are both vulnerable and valuable.

Vulnerability scan – is an exploit using a special program to access weaknesses in computers, systems, networks or applications in order to generate information for planning an attack.

App attack – is an attack against an application or service that is not running on the web, ie the program will be on a computer somewhere.
