Eyes away from the computer monitor how much distance as well?

The use of computers, computer monitors the number of eyes from a distance of good?

At least one meter's distance.Foot away from the eyes of the display Distance of 60cm for good.

If you still feel that the eyes adjusted, you can buy a liquid crystal film so as to minimize the purpose of reflection, would a little uncomfortable eyes.

It has been reported that Chinese women 20 reported in the survey, researchers tested 10 different brands of 19-inch LCD screen, both desktop and notebook computers have.They found that tested the liquid crystal display there are “too high brightness “.Researchers pointed out that when the display brightness per square 100cd (that is, strength of light-emitting unit,” Candela “), the eyes have been affected to a certain degree.And they are testing the liquid crystal display, the luminous intensity Per square meter more than 300cd, and some even reached 400cd-500cd.

Presided over the investigation of the German computer experts said that LCD is not only computers, LCD TVs there is the problem.These liquid crystal display screen in order to Increase the clarity, not only on the screen behind the fluorescent tubes to enhance brightness, but also the widespread use of a special “technical polish,” so that the display mounted on the surface looks like a piece of glass, appears to have texture, but also increased the screen The contrast and color saturation.But it will be like a glass-like reflection of light.Especially when the light to shine in the screen, will increase the reflection of light.The use of this display of the consumer, it is easy to be light, “stabbed” and have eyes The symptoms of fatigue, will slowly decline in vision and headaches caused health problems.

In that case, how can we prevent the liquid crystal display on the eyes hurt? Experts proposed:In order to prevent the reflection of light, the use of computer Our eyes and the distance from the screen to about 60 cm is appropriate; Second, the general brightness of the LCD has the function of the level design, using, as far as possible to tune brightness; Third, in the liquid crystal display may be posted on On a light anti-reflective LCD screen protective film, which not only prevents damage to the LCD screen, you can stop the emergence of the phenomenon of dizziness and light reflection.In addition to updating the computer to prepare those who might choose to emerging market-based There are low-reflection LCD technology, LCD, which is designed to avoid the light of the eye injury
