What’s Computer vision syndrome (CVS)?

Computer vision syndrome (CVS) is a temporary condition resulting from focusing the eyes on a computer display for protracted, uninterrupted periods of time. Some symptoms of CVS include headaches, blurred vision, neck pain, redness in the eyes, fatigue, eye strain, dry eyes, irritated eyes, double vision, polyopia, and difficulty refocusing the eyes. These symptoms can be further aggravated by improper lighting conditions (i.e. glare or bright overhead lighting) or air moving past the eyes (e.g. overhead vents, direct air from a fan).

Causes of Computer Vision Syndrome

Low Contrast: This is not a new concept for most people. The pixilated nature of the objects on a computer screen engenders low contrast. This is especially true of text on computer screen. Studying objects of low contrast causes eye strain, which can lead to CVS.

Prolonged Use: Most people work 8-9 hour days. Even if you take a 1 hour lunch break, this still leaves 3.5-4 hour periods during which you are staring at a computer screen. Extended viewing of a computer screen (over 2 hours), especially at a constant depth of field, is the primary cause of CVS.

Reduced Eye Movement: During activities in which they are not focused on a computer screen, the average person blinks about 16 times per minute. While looking at a computer screen however, this drops to 6 times per minute. In addition, they eye moves through a lesser range of motion when concentrating on a screen. This reduction in eye movement serves to dehydrate the eye, which can, among other things, lead to CVS.

Backlit Screens: Computer screens are -backlit-, meaning the light that illuminates the screen shines directly into your eyes. Most every other source of light we incur is first reflected off an object, entering our eyes at a lower amplitude. Staring at direct sources of light is hazardous, and can lead to CVS.

Prevention of Computer Vision Syndrome

For as serious as some of the effects of CVS can be, prevention of the condition is surprisingly easy. If you work in front of a computer screen on a daily basis, take these simple steps to avoid CVS and other eye-related problems.

Take a Break: Staring at a screen for an extended period of time is the leading cause of CVS. If you must work an entire day in front of the computer, make sure you take at least a 5 minute break every hour, and allow your eyes to relax. Looking out the window works great here.

Increase the Contrast: Modern computers have display adjustments either on the screen, in the -control panel- of the operating system, or both. Using these controls to increase the contrast of your computer monitor can make looking at the screen much easier on your eyes.

Blink: Making a conscious effort to blink more often while working at the computer will build a healthy habit sure to make your workday more comfortable. As you begin this exercise, use eye drops to help keep your eyes hydrated.

Put on eyewear: Glasses for computer can well block blue light and radiation from computer. Currently on the market, e-healthmate professional computer eyewear are nice choice for CVS.

These past few years have seen the emergence of the laptop as a popular device among professionals and students. Gone were the days when only a select few can afford to buy laptops. Due to the advances made in technology, the prices of laptops have been constantly going down. It is for this reason that people wanting to purchasing their first computer are considering laptops instead of desktops.

Having doubts in purchasing a laptop? Let’s try to clear your apprehensions by listing the benefits of using a laptop computer.

Portability

People who want to bring around their computers should consider getting a laptop. Laptops right now are designed to be light enough to carry around and durable enough to withstand constant travel. If you are going to give a presentation during one of your office meetings then you can prepare the presentation at your home using the laptop and bring the laptop over at the meeting. This way you would be sure that the presentation would go smoothly. Students and businessmen prefer to use laptops than desktops because it is convenient to carry around, just put it in your sling bag and bring it anywhere.

Less Power Consumption

Because laptops use smaller components when compared to desktops, they consume less power. On an average, a single desktop is equivalent to 3 laptops in terms of power consumption. This means that if you want to save in your power bill get a laptop instead. Although most high end laptops cost a lot, the savings you get in the long run from power bill would be worth it.

Space Saver

A laptop is great for people who have little space to spare in their houses. Let’s face it, if you buy a desktop you also have to buy a computer table and computer chair. This would then eat up what little space you have in your house. By getting a laptop you wouldn’t be having this problem at all since you can use your laptop anywhere. You could use it while sitting on the couch or while in your bed.
Productivity

Laptop owners are generally more productive since they can always finish up their work during their spare time. You can do your presentations or your emails while you are traveling on a plane . Instead of just sitting around doing nothing, with a laptop you can finish work that needs to be done. After finishing up your work you could then relax by playing that favorite movie you just downloaded while waiting for the plane to arrive.
These are just some of the benefits you get when you purchase a laptop. Laptops nowadays are becoming as powerful as desktops as well. A couple of years ago only desktops could properly run graphics intensive software. Today the playing field is level with laptops able to properly run 3D applications and processor hungry software. Whether your field of expertise is engineering or design, laptops can assist you in your daily work.

If you need to purchase a computer why not make your choice a laptop. You would definitely enjoy owning one.
