Millions of people spend long hours working at their computers and if you are one of them your computer monitor could be doing real harm to your eyes. Sore and tired eyes headaches and blurred vision even nagging back pain from straining to see your monitor are all symptoms of computer vision syndrome or CVS. CVS can affect anyone who works on a computer while maintaining good posture is an important part of the solution a prescription for customized computer lenses can significantly reduce many of the symptoms that you may be experiencing. Customized computer lenses are different from regular eyeglass lenses. Regular eyeglass lenses may be good for reading or driving but they are not always suitable for computer work. Computer lenses are uniquely designed to make it easier to focus at the distance of your computer monitor and reduce the glare caused by the lighting in your working environment. These lenses can also be given special tents and lens coatings that provide sharper vision and better protection for your eyes. Computer glasses are not intended to replace your regular eyeglasses. They are recommended as a second pair of glasses because they are customized to provide enhanced vision specifically for the workplace environment.

Syndrome

Do you have tired or sore eyes? Headaches, blurred vision and general fatigue? If so like millions of people you may be suffering from a problem called computer vision syndrome or CVS. CVS is the number one health complaint in the workplace and affects everyone who works on a computer. Your computer screen projects images and tiny pixels. Although you are probably not conscious of it these pixels constantly change and your eyes must refocus with each change. This constant adjustment constrain your eyes. Your eyesight will start to become distorted or blurred. Your eyes may have difficulty focusing. In many cases you may experience headaches, neck and back pain. There are ways to help CVS though. One of these ways is to wear a pair of computer glasses. These glasses reduce the glare on a computer screen allowing your eyes to focus more easily. Other ways to determine the symptoms of CVS are to set up your work area in such a way that it is easy to view your computer screen which should be straight in front of you about 24 inches away from your eyes and out of the sun’s glare. In addition you may use a desk lamp to create a more focus light where you are working for more information ask your doctor about computer vision syndrome or CVS.

Blue Light

Every day we are exposed to increasing amounts of blue light. Outdoor exposure to blue light comes from the sun while indoor exposure comes from artificial sources of blue light such as computers, tablets, cell phones, televisions and modern energy-efficient light bulbs. Over time, blue light can impair our daily visual performance, disrupt our ability to sleep and contribute to the development of macular degeneration a devastating eye disease that can lead to vision loss. Constant exposure can impact visual performance by increasing sensitivity to glare, reducing contrast and color perception and decreasing visual acuity. Ask your eye care professional how you can protect yourself and your loved ones from the dangers of blue light exposure.

Ergonomics tips

Here are some of the top computer ergonomics tips recommended by the U.S. Department of Labor’s Occupational Safety & Health Administration (OSHA). These tips are designed to reduce the risk of stress, physical injury and computer eye strain from prolonged computer use.

  1. Sit so your head and neck are upright and in-line with your torso, not bent down or tilted back.
  2. Face your computer screen directly. Avoid viewing your screen with your head turned or your back twisted.
  3. Keep your elbows comfortably close to your body.
  4. Use a chair that provides support for your lower back and has a cushioned seat with a contoured front edge.
  5. Keep your mouse close to your keyboard so you don’t have to reach for it.
  6. Position your computer display so the top of the screen is at or slightly below eye level. This will allow you to view the screen without bending your neck.
  7. Adjust the position of your display to prevent reflections of overhead and outdoor lighting appearing on your screen.
  8. Put your monitor close enough to your eyes so you can comfortably read text on the screen without leaning forward.
  9. When working with print documents, use a document holder that positions them at the same height and distance as your computer screen.
  10. Use a hands-free headset when talking on the phone while working at your computer.

Also, adjust the height of your chair and desk so that:

  • Your upper arms are perpendicular to the floor, not stretched forward or angled backward
  • Your forearms, wrists and hands form a 90-degree angle with your upper arms
  • Your thighs are parallel to the floor and your lower legs are perpendicular to the floor
  • Your wrists and palms are not resting on sharp edges

If you wear bifocals or trifocals, you should be able to comfortably view your computer screen without tilting your head back. If this is not the case, consider purchasing computer glasses.
Following these tips will help you avoid stressful postures that lead to headaches, neck and back pain and computer vision syndrome.
But remember, prolonged computer work — even at an ideal workstation — is stressful to your body and your eyes.
To relieve stress that can lead to computer vision syndrome and physical disorders, be sure to take frequent breaks when working at a computer.
Many experts, including optometrists who specialize in computer vision, recommend that you get up and move away from your computer for short breaks at least every 20 to 30 minutes.
Take a few minutes to stretch your arms and back, and let your eyes relax their focus by looking at something at least 20 feet away.
Also, blink fully and frequently to reduce your risk of dry eyes from computer use. If necessary, apply “artificial tear” eye drops to moisten and lubricate your eyes.

Where to Buy Computer Glasses

Resist the temptation to buy over-the-counter reading glasses for use as computer glasses.
Because an accurate eyeglasses prescription is essential if you want to get the full benefits from computer glasses, it’s best to purchase this eyewear from a knowledgeable eye care professional.
Prior to scheduling your eye exam, measure how far you like to sit from your computer. Measure from the bridge of your nose to the surface of your computer screen.
Bring this measurement with you to your exam so your eye doctor can use it to help determine the optimum lens power for your computer glasses.
