We prevent eye damage from computer!

          Eye pain is the most common complaints when working too long at the computer. These complaints if left unchecked could develop into the damage that causes blurred vision. To avoid this, apply the 20/20/20 rule, okay ... "The human eye is designed to look three-dimensional objects. On the screen, the eyes are forced to stare at two-dimensional object, "said Andrea Thau, OD optometrists from the American Optometric Association, as quoted by MSNBC. Coercion by Thau make the brain work harder to interpret the image captured by the eye. Fatigue of the brain that will make processing light signals from the eyes is interrupted, then perceived as a blurred eye complaints. In addition, the normal human eye can only see comfortably when the focus is at a minimum distance of 20 feet (about 6 meters).

          While in front of the computer, the eye is forced to re-focus the view at a distance of less than 2 feet (about 60 cm). Coercion-coercion which sparked some of the complaints referred to as Computer Vision Syndrome (CVS). Symptoms are, dry eyes, headaches and if allowed to continue would result in vision was blurred or unfocused. According to Thau, overcoming the syndrome, does not have to be done by removing the computer from everyday life because after all, we need technology to support its productivity. What needs to be changed sebernarnya just how to use it. For those of you who work demanding to sit for hours in front of the computer, it is recommended to apply the 20/20/20 rule. This means that every 20 minutes, a time to turn the view from the screen for 20 seconds to another point within 20 feet (about 6 meters). Oh yes, do not forget to blink, because the average person just flashes 6 times / min while being engrossed in front of the computer.  

          So that the eyeball is dry and does sting, the lids should always blink of approximately 16 times / minute. If you can, position the monitor so that no higher than eye level and minimal. If the eyelid is too high then we tend to work harder to blink and eyeball wet, so that the edges so forget to blink.
