   More and more professionals are using computers to one degree or another, just as in the homes of an increasing number of families considered important computer device. But the long hours of work, sitting behind the monitor, can lead to vision problems, in the event of your negligence, experts warn.

   Studies have shown that eyestrain and other vision problems can occur in nine out of ten, using the monitors at work.

   The most common symptoms of these problems - it is eyestrain, amblyopia, split vision, excessive formation of tears, dry eyes, too frequent blinking or squinting.Visual problems can also cause physical problems such as headaches, sore shoulders or neck.

"
   When people come to us with such symptoms," said Dr. Kerry Beebe, a representative Optimetricheskoy Association (OA), we automatically ask them: 'What do you do most of the day? "They often spend a lot of time working on the computer" .

   Moreover, the radiation produced by a computer screen does not have these symptoms, no relation, though it is - a common myth.

   "People often ask about UV radiation, but any UV radiation from the computer screen is minimal," said Dr. Jeffrey Weaver, director of the clinical group of OA, "If you do not get a tan from working for a computer monitor, then that is no reason for concern."

   But if you develop any of the above symptoms during or after computer use, you should consult a physician for examination.

   In many cases, when an issue of focus, simply wearing glasses while using the computer.We also recommend taking frequent short breaks every half hour. During these breaks, lasting one or two minutes, focus your eyes on a distant object, it will help refresh the vision. A mere glance away from the window of a room or can be very alleviate eyestrain.

   The brightness of the monitor should be adjusted to the intensity, easy on the eyes.This means that the monitor should not be too bright or too dim.

   Then, you can adjust the contrast between the characters on the screen and its background, so that would have printed the text was easily readable.

   And, finally, minimize the reflection of bright light on the monitor, using tinted windows or curtains on the windows, and adjust the lighting the lamps. Bright light sources should also be excluded from the peripheral vision.

Most offices tend to be too bright for use in their computers.

   To further reduce glare, place the owl workplace so that it would be possible, perpendicular to the window or other bright light sources. You can also buy a matte screen on the monitor, or wear sunglasses.

   Dry eyes - this is another common complaint, for two reasons. Offices usually have a dry environment, and when people read the computer screen, they tend to blink less.In order to reduce dry eyes, take frequent breaks and keep artificial tears at itself - a special eye drops.You can also reduce eyestrain by placing monitor in an ergonomically correct position. The monitor should be located at a distance of 40 to 76 cm from the eye, depending on how big the screen is and how good your eyesight. Most people find it most convenient to have computer screen at a distance of 50 to 66 cm

   The top of the monitor should be slightly below the level of your eyes. Center of the monitor should be at an angle of 10 - 20 degrees below the eyes, or approximately 10 - 23 cm below the eyes, the distance from the monitor at 60 cm

   And do not forget to adjust the monitor when the computer sits your child. In most cases, or a computer monitor too high or too low chair or table is too high. Place the computer as possible should have an adjustable chair that can be raised for the comfort of the child.

   In the process of technology development and reduced eye strain, in order to help prevent vision problems. In the monitors have improved contrast and resolution, and LCD-monitors (liquid crystal display), in particular, are easier on the eyes. Monitors also include filters to reduce the brightness of light, in order to prevent reflections cause eyestrain.
