Our society is really obsessed with the usage of computers and with good reason. About ninety-five percent of our livelihood depends on computer technology. But this is only the beginning of the problem: problems with our eyes. What is Computer Vision Syndrome? For those of us that are on a computer for a certain period of time on a regular basis, it is likely that we will suffer from blurred vision and some symptoms of Computer Vision Syndrome, or CVS. This includes eyestrain and tired eyes during the time at the computer. Everyone that has worked and/or operated on computers has experienced some or all of these dilemmas. It is not the end of the world; there are some solutions to the eye straining problems that are associated with using the computer. Computer glasses are one of the solutions. Not many individuals would think to purchase any of these glasses. Instead, they choose to get regular glasses, which are not equipped for computer usage. However, computer glasses are less economical than most regular glasses. These glasses are custom-made to take on the eyestrain and to allow individuals to feel comfortable and at the same time have the efficient vision at the computer. Type of Screen Matters If having computer glasses is not the only option for individuals, then there is also the computer screen. This type of screen is referred to as the intermediate zone of vision, which is the computer distance but it is also farther than the reading distance, as in reading a book. If the proper computer glasses are not worn, and then it is likely that computer user will have blurry vision along with back pain, headache, a few sore limbs, and of course, straining the eyes. The following are a few of the specially designed equipment for the computer glasses: The simple vision lenses are the basic forms of computer glasses, which includes modified lens powers. This allows the computer users to see comfortably during his/her computer session. One of the requirements of the simple vision lenses is to keep subjects in perspective in terms of the distance of the computer. It also gives the largest field of view-this limits the risk of straining the eyes, having blurry vision, and having a less than perfect sitting posture, which can lead to back and neck pain. Unlike the simple vision lenses, the occupational progressive lens is designed for individuals with presbyopia. An individual with these lenses can see from near, intermediate, and distance vision from a certain perspective. These progressive lenses have a much massive intermediate zone than regular progressive lens. The purpose is for computer users to have a more suitable vision during the computer usage: entertaining, working, reading or custom writing. However, the occupational progressive lens is not for driving or attempting to see very distant subject matters. Conclusion In addition to the simple vision lenses and the occupational progressive lens, there is also a couple more lenses to choose: occupational bifocal, which consists of the top part of lens, which is for computer viewing and the bottom lens, which is for reading. There are also the lined trifocals, which has a larger intermediate zone. There are many options to choose from in terms of having better computer eyes. If we, the computer users, choose any or all of these options, we will feel much better and so will our eyes.
