After a few hours in front of the computer, vision starts to blur and eyes often start to burn. PCLens(r) technology has both the correct diagnosis for these computer-related vision problems and a suggested cure - their patented clip-on lens - the PCLens(r).
The Cause: Computer Vision Syndrome
The proliferation of computer users has led to an explosion of computer-related eyestrain, which even has a name. It's called "Computer Vision Syndrome". Nationally over sixty-six million computer users suffer from eyestrain, blurred vision, tired eyes, migraines, shoulder tension, headaches, and neck aches, etc. By next year, nearly 75% of all jobs are expected to involve computers. So CVS is a growing problem.
During the 1950's scientists discovered when looking at an elevated object at arm's length distance, your eyes rotate outward in opposite directions; this process was labeled excyclorotation. Because of excyclorotation, the surrounding eye muscles must then turn the eyes back in and hold them in that corrected position.
By the 1990's computer work had become commonplace, and using an elevated gaze to view a desktop monitor at arm's length was the norm. The tilting of the head to compensate for the elevated position of the monitor and the repeated gaze shift between monitor and keyboard along with the impact of loss of focus brings us to CVS. Add to this situation the fact that most people experience a greater loss in the elasticity of their eye muscles somewhere around the age 38 and you can understand the OSHA (Occupational Safety and Health Administration) fact that CVS or computer eyestrain is outpacing Carpal Tunnel Syndrome as a high-tech affliction.
The Remedy: PCLens(r)
Why not get a bigger monitor? While this can make reading easier, bigger screens sometimes produce an even higher viewing angle. Regardless of the size of the screen, the brand of the monitor, or the font and type size, CVS can still attack.
Appropriately named, TiredEyes.com proposes a remedy to CVS - its PCLens(r). Now that "PC" is not "Personal Computer Lens" but "Prism Combination Lens." This new product is designed for people, especially bifocal wearers, who work on computers. The unique feature of this computer accessory is its integration of magnification with prisms. Prisms permit computer users to look down while their screen is up by optically lowering the work surface, which subsequently relaxes the muscles that control the eyes.
The Application
So how does the PCLens(r) work? After clipping the lightweight lens over your own prescription glasses, you view the monitor through the upper portion of the lens, the area containing the prism plus magnification. Position the prism section line just below the bottom edge of your screen. Use the lower portion to view your keyboard and desktop material, and when resting your eyes and looking off at a distance, remove or flip-up the lens. PCLens(r) is not a corrective lens; it is clipped to the user's glasses and works in conjunction with your prescription glasses.
The Look
With a thirty-day, money-back guarantee, you can try out a pair for yourself. The PCLens(r) is priced at $29.95 plus $4.00 for shipping and handling and is very easy to order. The Web site TiredEyes.com offers a choice of either the clip-on or the flip-up style. The clip-on comes in three shapes with various sizes; printing out sizing templates and ordering instructions makes the order process easy. The lightweight clip-on variety is easy to slip over your prescription glasses by gentling pulling out each side of the lens to extend the spring built into the bridge. When you release the lens, four clips slide over your regular glasses. The flip-up style comes in a small and large size and is similar to the popular sunglass version; just flip them up to see at a distance.
Neither version is cumbersome-looking; they are fairly inconspicuous. These PCLens(r) do have a definite bifocal line so if you are a progressive bifocal wearer, you will need to get used to the visible line when you are wearing the lens. Tired Eyes has the bifocal wearer in mind, but the regular glasses wearer and the non-glasses wearer will be happy to know a product for them is on the drawing boards.
An attractive point for PCLens(r) is that many vision products and prescription glasses must be replaced as your eyes change, on the average, about every two years. The PCLens(r) never has to be replaced and always works with your current prescription, unless you change prescription frame size or style or you lose your PCLens(r). Losing them will not be a problem if you use the included carrying case that neatly attaches to the side of your monitor with a Velcro tag. A suggestion: put your receipt and warranty information in your lens case on the side of your computer. Although there is a one-year warranty against manufacturer's defects, for warranty replacement you will need the original receipt, lens, and check or money order for $5.95 to cover shipping and handling.
PCLens(r) was invented by Stuart M. Lazarus, O.D., and several ophthalmologist are now backing their use and endorsing the beneficial effects of PCLens(r) in preventing CVS. From research figures, the company assures us there seems to be no long or short-term side effects of using the PCLens (r). Their generic style prism combination lens used in conjunction with your own prescription can go a long way in providing relief from computer eyestrain. In computer lingo that is CVS + PCLens (r) = .
