In years gone by, the major eye care problems affecting Barbadians were glaucoma and cataract, but today there are new risks to their eyes.
With widespread access to computers, video games and DVD players, the average Barbadian now spends a great deal more time using their eyes than was the case, for example, 15 years ago.
In a typical day adults stare at a computer monitor for hours. Children, too, spend several hours on hand-held and television attachable games. These activities can put significant strain on the eyes.
Eye problems or complications from computer use are called computer vision syndrome (CVS). Some of the symptoms of CVS include blurred vision; double vision; dry, red eyes; eye irritation; headaches; neck or back pain.
According to WebMD, between 50 and 90 per cent of people who work at a computer screen have at least some symptoms of eye trouble. In addition, children who stare at portable video games or who use computers throughout the day at school also can experience eye problems, especially if the lighting and computer position are less than ideal.
WebMD continues: “Working at a computer requires that your eyes continuously focus, move back and forth, and align with what you are seeing. You have to look down at your papers and then back up to type, and your eyes have to accommodate to changing images on the screen in order to create a clear picture for your brain to interpret.
“All of these functions require a lot of effort from your eye muscles. Working on a computer is more challenging to your eyes than reading a book or piece of paper, because a computer screen also adds the elements of screen contrast, flicker, and glare.”
Preventing or at least minimizing computer vision symptoms in the work environment can be accomplished by making a few simple changes. These changes include cutting out the glare. This can be done by changing the lighting or simply putting a glare filter over your monitor.
Rearranging your desk can also help. The best position for your computer monitor is slightly below eye level and about 20 to 28 inches away from your face.
Also place a stand next to the computer monitor to place your printed material. That way you would not have to look up at the screen and back down at the desk while you type.
Take frequent breaks, looking away from the screen every minute and either gazing out the window or scanning the room for about 20 seconds to rest your eyes. Blink often to keep your eyes moist. If your eyes are getting overly dry, try using lubricating eye drops.
The adjustment of the computer setting could also be beneficial. Adjust the brightness, contrast and font size until you find the best settings for your vision. If all else fails, visit the doctor for an exam and let the doctor know about any eyestrain or other problems you’re experiencing at work. The ophthalmologist can then determine whether you need to wear glasses or contact lenses to correct your eye problems.
