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%!

Important Size, Shape and Weight Considerations: All the usual brands of clip-on’s sold on the internet are all larger in size and weight. A possible reason for this is that these clips were designed when eyeglass sizes were larger some twenty years ago. The smallest size I found was 58 mm X 30 mm, and even this smaller clip-on still was too large a size for today’s eyewear, and weighed 40% more than the CCC. Unless you are comfortable with millimeter measurements you are not sure what the size really is when purchasing on the internet. Heavier clips have a dramatic effect on the center of gravity of eyeglasses, and consequently, help pull the frame down on your face with the extra weight. The larger sizes make it difficult for you to use the reading portion of your general wear glasses at a normal reading focus. The extra magnification over the bottom reading area means you will now need to hold reading material closer than usual. The clamping arms that secure the clip to the user’s lenses had a minimal rubber coating dipped onto the clamp tips to protect the eyeglass lenses from scratching when taking the device on and off.

CCC’s were designed to be made to cover only the upper distant portion of your general wear eyeglasses, and are as much as 48% lighter in weight than general wear clips. The lens measurements are 51 mm X 26 mm. This size works well even on light weight rimless eyeglasses. The reduced weight of the computer conversion clips help to keep your current eyeglasses up in place with less trouble. The shape and size design feature turns your general wear glasses, with the CCC’s attached, into a task specific computer and reading eyeglass for greater utility both on the computer or working in a cubicle. You can always flip-up the computer conversion clip to see clearly at distances over 20 feet. The clip-on clamps that secure the device to the user’s glasses have soft gripping boots on the tips of the clamps to prevent the device from accidentally scratching the eyeglass lenses when attaching or taking off the clip-on.

Bonus Benefits of CCC’s: Depending on the age of the individual Computer Conversion Clips come in two easy to understand dynamic powers from which to choose. A custom made crush proof case to protect the clip-on along with a micro-fiber cloth for cleaning is included. ECP’s can give you additional advice, or you can use the below resource box to find answers to any additional questions; along with access to other facts and questions the CCC’s comes with a money back guarantee.

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.

Honeypots

A honeypot is a decoy website, network, system or application that has been intentionally designed to be vulnerable to attack. Its purpose is to gather information about attackers and how they work.

Honeypots allow researchers to:

• collect data on new and emerging malware and determine trends in threats
• identify the sources of attacks including details of their IP addresses
• determine how attacks takes place and how best to counteract them
• determine attack signatures (pieces of code that are unique to particular pieces of malware) so that anti-virus software can recognise them
• develop defences against particular threats

Honeypots have proved to be invaluable in erecting defences against hackers.

The Spring 2014 Cloud Security Report

Alert Logic provides security services for both on-premises and cloud computer systems. The company began issuing cloud security reports in 2012. Its Spring 2014 Cloud Security Report covers the year ending 30th September 2013.

This report is based on a combination of real-world security incidents experienced by Alert Logic’s customers and data gathered from a series of honeypots the company set up around the world.

The report throws some interesting light of the security of on-premises and cloud computing relating to the company’s customers. Here are some of the highlights:

[1] Computing is shifting more and more from on-premises to cloud-based computing and the kinds of attacks that target on-premises systems are now targeting cloud environments. This is probably due to the increasing value of potential victims in the cloud.

[2] Although attacks on cloud environments are increasing in frequency, the cloud is not inherently less secure than traditional on-premises computing.

[3] The frequency of attacks in both on-premises and cloud computing has increased for most types of threats, though for a few types of threats it has fallen. Here are the main points of comparison between both computing environments:

The most prevalent types of attacks against on-premises customers were malware attacks (including botnets) at 56% during the six months ending 30th September. At only 11%, these attacks were much less frequent among cloud customers. However the number of cloud customers experiencing these attacks is rising quickly, more than doubling in one year.

Attacks using brute force increased from 30% to 44% of cloud customers but remained stable in on-premises environments at a high 49%. Vulnerability scans jumped dramatically in both environments. Brute force attacks and vulnerability scans are now occurring at almost the same rates in on-premises and cloud environments.

Web app attacks are more likely among cloud customers. However these attacks are down year-on-year in both cloud and on-premises computing, as are recons. App attacks increased slightly in both categories of customers.

The most prevalent types of attacks vary between on-premises and cloud environments. In on-premises computing the top three were malware (56% of customers), brute force (49%) and vulnerability scans (40%), while in the cloud the most common incidents were brute force, vulnerability scans and web app attacks, each of which affected 44% of customers.

[4] The incidents involving Alert Logic’s cloud-based honeypots varied in different parts of the world. Those hosted in Europe attracted twice as many attacks as honeypots in Asia and four times more than honeypots in the USA. This may be due to malware ‘factories’ operating in Eastern Europe and Russia testing their efforts locally before deploying them throughout the world.

[5] Chillingly, 14% of the malware collected by honeypots was not detectable by 51% of the world’s top antivirus vendors. Even more frightening: this was not because these were brand-new malware; much of the malware that was missed was repackaged variations of older malware and thus should have been detected.

The report concluded with a statement that security in the cloud is a shared responsibility. This is something that individual entrepreneurs as well as small and medium sized enterprises tend to forget.

In cloud computing, the service provider is responsible for the basics, for protecting the computing environment. But the customer is 100% responsible for what happens within that environment and, to ensure security, he or she needs to have some technical knowledge.

Conclusion

Advertisements by cloud service providers seem to imply that cloud computing is safer than an on-premises computing. This is simply not true. Both environments seem to be equally safe or unsafe viz-a-viz hackers and their malicious programs.
