Eye fatigue or eye strain, sometimes known as computer vision syndrome, affects about 50-90% of computer workers. The problem is expected to grow as more people use smartphones and other hand-held digital devices. Digital devices may also be linked to eye fatigue because of a tendency to blink less often when staring at a computer screen.
- Sore or irritated eyes
- Difficulty focusing
- Dry or watery eyes
- Blurred or double vision
- Increased sensitivity to light
- Pain in the neck, shoulders, or back
These symptoms can decrease productivity and may be intensified by sleep deprivation. During sleep, the eyes are replenished with essential nutrients. Lack of sleep may result in persistent eye irritation. Sometimes this can cause a tiny (white) bump on the edge of the eyelid called a stye, or inflamed oil gland. This can make it feel like your eyelid is made of sandpaper.
Vision is a precious gift. Work to preserve it by getting sufficient rest and making regularly scheduled visits to an eye care professional. If eye fatigue persists despite taking simple precautions, see your doctor.
