Eye strain, red eyes, blurring vision and other symptoms of computer vision syndrome are often felt when you work at a computer for prolonged periods of time. This is due to the visual demands of computer work which is not associated with most other activities. If you are under the age of 40, blurred vision and eye strain during computer-based work may be due to the eye's inability to remain properly focused on the screen or your eyes having trouble changing focus from the screen to the keyboard over prolonged periods of time. These focusing problems are often associated with CVS.
If you are over the age of 40, eye problems associated with computer work may be linked to an onset of presbyopia which is a normal age-related near focusing ability loss. This can also be a cause of the CVS symptoms.
The question that many people ask is what they can do about this. The first step will be to have a comprehensive eye test done to rule out any major vision problems and to update your eyeglass prescription. Small inaccuracies in your prescription lenses can contribute significantly to your computer vision problems. If your prescription eyewear is up to date and you continue to have problems, you should consider getting customized computer glasses. These are special glasses that are prescribed to reduce eye strain and give you the most comfortable vision possible while you work at the computer.
Why Choose Computer Glasses?
Regular eyeglasses and computer glasses are different in a number of ways because they are optimizing your eyesight for computer screens. Computer screens are generally 20 to 26 inches away from the eyes. This is considered to be the intermediate area of vision as it is closer than distance vision but farther than near vision.
When young adults and children are prescribed eyeglasses, they will generally be given single vision lenses. These are used to correct nearsightedness, astigmatism or farsightedness. The shape of the eye lens will also adjust when these glasses are used to provide the magnification needed for computer vision and near vision.
When near vision becomes less clear with presbyopia, this age-related loss of focusing powers will affect your ability to read and see computer screens and phone screens comfortably and clearly. Bifocal lenses can be used to get clear near and far vision, but intermediate vision will generally remain a problem. Trifocal and progressive lenses can be used as they will offer help for intermediate vision, but the intermediate zone that they have will generally not be large enough for comfortable computer work.
Without the use of computer glasses, many users will have blurred vision, headaches and eye strain which are the symptoms of CVS. To compensate for the blurred vision, there are many people who will lean forward or tip their head to look through the bottom part of their glasses. Both of these actions can result in sore shoulders, necks, and backs.
Computer glasses are often called computer reading glasses and are specific eyewear that has been created to help with computer use. It is important that these glasses are distinguished from traditional reading glasses.
