Computer Vision Syndrome - Quick Review
The Computer Vision Syndrome

Close to 150 million people sit in front of a computer monitor each day. Many of them spend more than two hours at a time, focusing on screens as they complete work projects, blog, or just surf the web. If a significant portion of your day involves computer time, you may be at the risk of CVS-Computer Vision Syndrome too.

What is Computer Vision Syndrome?

According to the American Optometric Association, CVS is a set of symptoms that are all related to working with a computer. These symptoms can affect both the eyes and musculoskeletal parts of the body. Very simply, CVS occurs when an individual overburden the human eye by asking it to perform in prolonged situations that it was not designed to do. Studies have found that the majority of video display workers experience some eye or vision symptoms. A national survey of doctors of optometry found that more than 14% of their patients present with eye or vision-related symptoms resulting from this type of work. The most common symptoms are:

• Blurred Vision when looking into the distance

• Double Vision

• Stinging of the eyes

• Excessive tearing of the eyes

• Headaches

• Neck or shoulder pain.

(Keep in the mind that these symptoms are generally experienced after prolonged periods of computer work or, over time, due to progressive eye strain associated with CVS).

What Causes CVS?

Unlike printed matter, a computer screen displays words and images through the use of pixels which are multi-dimensional and vary in contrast. The eye is always working extra hard to accommodate as it focuses and refocuses on the graded areas of these combined pixels. The eye lens must work harder to support the function of sight. Eventually, the eye tires and becomes lazy. This explains why vision blurs occur and why it is difficult to look away from the monitor and see distant objects clearly.

    There have been increasing costs related to health care services over the past few years due to growing number of chronic conditions [1]. A chronic condition (e.g. chronic headache, diabetes etc) can be any long term illness or condition that impacts one’s quality of life functionally and socially. It is estimated that chronic headaches affect 4% to 5% of the general population [2]. The focus of my research is to help patients use computing technologies who are living with chronic headache. Chronic headache patients have frequent headaches at an average of 15 days or more in a month [3].

    With blurred vision and eyestrain we must look at the optic nerve within the brain. From there, what could be causing the difficulty breathing and weakness? It must be a neurological problem involved with the synaptic centers. Since Annie is having such problems when she is working out hard and just playing around it can’t be related always to work, but to everyday tasks as well. Often we see that having eyestrain is just the beginning. Whenever you don’t see well other factors will play into it, like headaches, soreness, and fatigue. After working out though, we often have lactic acid buildup, which will cause fatigue and muscle weakness, so we must rule that out.…

    So, with the increasing use of computers, computer related-vision problems are affecting a growing number of individuals. Visual symptoms include: eyestrain, blurred or double vision, headaches, red or irritated eyes, and color perception changes. Other individuals may also experience neck or shoulder tension, general fatigue, or pain in the back, arms, wrists or shoulders. Improper workstation set-up, a fragile eye teaming or eye focusing system, or poor visual hygiene can aggravate these symptoms. Individuals who suffer from computer vision syndrome may find relief through specially designed prescription lenses, filters or vision therapy. If you experience tension, pain, or visual discomfort when using a computer, you may be suffering from a computer related-vision problem.

    Virtual Retinal Display

    The Virtual Retinal Display (VRD) is a personal display device under development at the University of Washington 's Human Interface Technology Laboratory in Seattle, Washington USA. The VRD scans light directly onto the viewer 's retina. The viewer perceives a wide field of view image. Because the VRD scans light directly on the retina, the VRD is not a screen based technology. The VRD was invented at the University of Washington in the Human Interface Technology Lab (HIT) in 1991. The development began in November 1993. The aim was to produce a full color, wide field-of-view, high resolution, high brightness, low cost virtual display. Microvision Inc. has the exclusive license to commercialize the VRD technology. This technology has many potential applications, from head-mounted displays (HMDs) for military/aerospace applications to medical society. The VRD projects a modulated beam of light (from an electronic source) directly onto the retina of the eye producing a rasterized image. The viewer has the illusion of seeing the source image as if he/she stands two feet away in front of a 14-inch monitor. In reality, the image is on the retina of its eye and not on a screen. The quality of the image he/she sees is excellent with stereo view, full color, wide field of view, no flickering characteristics.…
