Computer Vision Syndrome is Very Common with Extended Computer Use
What is Computer Vision Syndrome (CVS)?
If you work on a computer and experience headaches, eyestrain, blurred vision, fatigue, or dry, burning eyes, you may be experiencing computer vision syndrome (CVS). It is estimated that over 100 million Americans suffer from CVS. Your eyes behave differently while working on a computer than they do while reading a printed page. Printed material has dark characters against a light background with well-defined edges that allow the eyes to easily focus and to hold a steady focus. Computer characters are derived from the combination of many pixels. The nature of pixel characters is to remain bright in the center and dimmer towards the edges and for this reason they lack the contrast and well-defined edges of words printed on paper. This variability in image quality causes our eyes to have to continually focus and relax and focus again. The constant effort for your eyes to focus causes the symptoms described above.
For years, professionals have recommended changing the atmosphere around a patient’s computer work station with glare filters, lighting changes, increasing blink frequency, and other solutions to decrease the physical stress on the human ocular system. These suggestions help to alleviate some of the symptoms however many patients still continue to experience eyestrain.
One of the biggest problems that causes computer vision syndrome is a lag of accommodation which usually requires a special optical prescription to alleviate symptoms of tired eyes and headaches.
What is PRIO?
Using the understanding of what causes patient eyestrain symptoms at the computer, an examination technique has been designed which simulates the pixilated character pattern of a computer screen in the exam room. This unique class 1 medical device, called PRIO, is the only one on the market which can mimic the pixel pattern of a computer screen.
How does PRIO aid in relieving CVS?
The PRIO system aids in measuring the precise prescription at your computer working distance. The goal of the PRIO exam is to prescribe a correction which keeps the computer screen focused for you while your eyes are in a relaxed state. Combing the perfect computer vision correction with changes in your computer work environment, symptoms of headaches, eye strain, watery eyes, redness, blurry vision, dryness can be a memory of the past.
