Go to: Previous Article Next Article
If you face symptoms of ocular pain, or eye strain, at the microcomputer you are not peculiar; it's the most noteworthy complaint among personal computer users. The following will help you understand the causes of unpleasantness and what you can do about it. An everyday complaint among personal computer users, especially those who wear contact lenses, are dry or itchy eyes. This is mainly due to the fact that we tend to blink only one-fifth as much when looking at a computer crt when compared with reading from paper. Combined with the modest humidity levels found in many offices, this results in a drying and irritation of the eyes. If you experience dry eyes, try lowering your display so that you are looking slightly down in order to promote blinking. Make
sure that exhaust fans from devices and from the building's ventilation system aren't blowing immediately on you. If dryness and irritation continue, see your eye care professional.
Your eyes are adapted for distance vision; they are most relaxed when you are "staring off into space". However, most of the work that you do in the office, whether it's reading from papers or the computer monitor, is done comparably near to your eyes, and this can cause optic pain. This is because diminutive muscles within your eyes have to work to turn your eyes inward and alter the shape of the lenses to focus for close vision. When these muscles fatigue you can experience symptoms of tired, sore eyes the same way that your back muscles will feel tired and irritated if you sit for too long in the same position.
When you glimpse down, your eyes have a common habit to turn inwards and focus for near vision, since things that are lower in your field of vision tend to be closer to you. The opposite is true of looking straight ahead or upwards - your eyes tend to turn outwards and focus
at a distance, and you will have to work harder to focus on close objects with your head in this angle. This is why, when reading from a book or a newspaper, we tend to hold it
less than eye level. If you read from a monitor or document that is located at eye level or higher, it can contribute to ocular exertion.
While having your monitor too close or too high can increase your chances of having optic pain, having it too low or too far away can result in stiff postures as you lean forward to look at it.
