If you are a person who spends a lot of time in front of a computer screen then you could, if you are not careful, easily end up suffering from Computer Vision Syndrome or CVS. In these modern times when more and more people are sitting for extended periods of time in front of a computer screen, it is not uncommon for them to suffer from CVS. This condition can lead to blurred vision, tiredness of the eyes and strain to the eyes.
If you are in your early thirties and you suffer from blurred vision then you will find it hard to focus your vision on the computer screen for extended periods of time. If you have passed your fortieth birthday and you suffer from blurred vision then your problem has more to do with age than with your eyes. Either way, you will need to use computer glasses to rectify your vision.
If you suspect that you need computer glasses then the first thing that you should do is consult your eye doctor. They will identify the problem and recommend suitable corrective measures which may include wearing computer eyeglasses. There are many good reasons to wear such glasses because according to research findings computer eyeglasses can help to increase your productivity levels. Even the slightest problem with acuity can lead to degradation of efficiency among computer users and workers.
Wearing computer eyeglasses will help to improve your productivity by about ten percent. If you already are wearing corrective vision eyewear and you want to use computer glasses then you will need to address a few issues. You should understand that computer eyeglasses are not the same as regular or even reading glasses. The glasses that are designed for use in front of a computer screen are meant to correct vision at a distance of between twenty and twenty-six inches from your eyes. This distance falls between driving distance and reading distance. If you are young and a computer user you will do well to wear special eyewear.
Corrective vision eyewear that is designed for computer usage is not suitable for driving and for general purpose. The simplest such eyewear has single vision lenses with a lens power that has been modified to allow you to comfortably view matter on the computer screen. This special lens power helps in relaxing the accommodation required to help you focus on objects on the screen and also provides a much larger field of view. These glasses are very beneficial as they help in reducing strain to the eyes and they also help to prevent blurred vision as well as an unnatural posture.
When your body is held in an unnatural posture it can cause pain in the back and neck. There is another option available to those who want to wear special glasses in front of the computer screen. This type of glasses is called the occupational progressive lens. Such lenses do not have lines but will help in correcting your near and intermediate as well as far vision. The intermediate zone will be larger than is the case with normal progressive glasses. You can also think about using occupational bifocal glasses as well as trifocal lens glasses to help you view matter on the computer monitor.
If you really are interested in viewing matter on the monitor comfortably then you need to choose your lenses very carefully. At the very least, these lenses should have an anti-reflective coating. This kind of coating is also called anti-glare coating and its main purpose is to do away with light reflections from both the front as well as a rear surface of your lens. You will also do well to add a light tint to the glasses as this will help in reducing glare and it also helps in enhancing contrast. The light tint also helps in cutting the blue light that comes from the computer monitor. This blue light is one of the leading reasons why computer users suffer from eye strain.
If you are going to spend long hours in front of a monitor then you will do well to not use regular reading glasses. Computer glasses have very accurate prescriptions which help to cut glare. When buying these items you must also make sure that you are buying from an eye care professional who is knowledgeable and an expert in such matters.
You should also get your eyes tested prior to making the purchase. This eye examination will help you find out the exact distance from the bridge of your nose to the monitor. To get maximum benefits you should get your eyewear properly fitted and you must make sure that you are using the latest prescription. your optometrist and ophthalmologist will know how to correct your vision. So, be sure to ask them for professional help and guidance.
