Tired syndrome that it must depend on to watch out for in the white collar clan
Introduction: The computer, while bringing convenience with fun for people, have brought greater damage to our eyes too, especially white collar working in front of the computer for a long time.
The computer, while bringing convenience with fun for people, have brought greater damage to our eyes too, especially white collar working in front of the computer for a long time. Reporter investigation find the intersection of great majority and person that work in front of computer for a long time, will feel eyes do, take place astringent, there are scorching hot senses or foreign matter senses; Some people's eyesight looks at things unstably and temporarily fuzzily; Someone has heavy eyelid even more, bloated pain of eyeball even headache Check through ophthalmology department, the white collar disease eyes of group appear conjunctiva to be congested, eyesight drops, regulate strength and fail, the tear is secreted and reduced, such symptoms as the intraocular pressure is raised when being serious, tired syndrome that diagnosed as by the oculist look at.
U.S.A. looks at the optical association to call this kind of eye syndrome as " Computer video terminal syndrome " . The investigation reveals, the person that often uses the computer, it is about 70% to suffer from tired probability of eyes. With studying, working, quickening of the rhythm of life, popularization and application of the TV, computer, look at tired to become the intersection of Chinese and white collar ill common eyes have too, and " computer video terminal syndrome " Look at tired the intersection of first and manifestation.
Ill
In the face of the computer, the sight is fuzzy gradually everyday
Zhong Hong does to a reporter in a newspaper office of Nanning, the income calculates payment according to manuscript quantity, quality, so, she writes for and makes money desperately. Every day is less than 1/4, but write for timing exceeds 8 hours, "I write the manuscripts of one and 500 words probably take 30 minutes, write 1500 words take more than two hours, write the article of more than 3000 words takes the time of more than 4 hours.
Facing toward the computer and beat the characters every day, exceed 8 hours once operating the computer, stay up frequently. Recently, I have always thought eyes uncomfortable, see the light sheds tears, fuzzier and fuzzier when seeing the things, what is the matter? "
Symptom last after the 2 month, Hong Zhong suspect oneself had glaucoma, goes to the hospital to see the ophthalmology department at once. Doctor tell her whether whom she suffer from to look at tired syndrome, result from using the computer for a long time.
Explain the puzzle
Watch the screen attentively for a long time, cause visual fatigue
"Operate the impact on eyesight to the computer, there is result of study that shows, operate the computer for more than 2 hours continuously, can make near-sighted strength drop, but can make eyesight return to the normal level after having a rest for 30 minutes. So, this stage is tired constitute a threat to vision, but accumulate to certain extent, may lead to the fact eyesight drops. "
Ophthalmology branch's Vice Chairman Hao XiaoBo in Guangxi of Chinese Medical Association analyzes, it causes tired factor of eyes to be numerous to operate the computer, the main one is to watch the computer screen attentively for a long time. Generally speaking, normal people blink about 20 times in one minute, and while using the computer to work, because too with fixed attention to fix one's eyes on, blink minute while being every number of times will reduce to being 6 time about.
Hao XiaoBo says, the tear sterilizes the function sterilized, still lubricate the eyeball, keep the cornea crooking all and systematic important function, excessive with the eyes will lead to the fact the tear is secreted and reduced, the tear composition changes, and then cause dry eyes. If the tear is secreted too little, the cornea can not be got all the time moistly, the surface of whole eyeball will become dry, the conjunctiva is congested, cause cornea damage, eyes appear scorching hot, foreign matter uncomfortable sense, present, look at thing to be unclear looking at the intersection of thing and symptom such as being tired finally.
In addition, posture and distance of operating the computer are improper, it is one of the reasons for bringing about fatigue in eyes. The distance of job is too near or the posture is incorrect, excessive close to the computer screen, eyes are all very easy to be injured, especially while using the notebook computer, because the screen is too small, user's necessary close quarter job, the head leans forward, shank muscles are exerted oneself, forming works tired, it is tired to aggravate eyes.
Some computers are because of duration too long, the screen luminance is reduced, definition fails, also will cause and read the difficulty. And the light of the working environment is too strong or too weak, will all cause screen and external world to produce strong contrast, it is amazing to cause eyes.
Different from the general books to read, the computer screen is the spontaneous mere display, there are the changes of luminance, contrast ratio, color, script size and interval,etc., still glimmer, definition is not good, luminance irregularity or unstable, etc, will all exert a bad influence on the visual system. The environmental factor around will also cause the screen blindingly, the vision emerges to obscure the phenomenon.
So, the vision of the spontaneous mere screen is stimulated and not merely come from information such as computer characters, figure, it is amazing to still come from the special vision of luminous body.
If the sight frequently moves and watches attentively between computer, keyboard and other things, the watching attentively rate can reach 60%-80% sometimes, cause the firm decline which looks at the function, control the firm brain nervous system function which looks at the movement to change, will influence visual efficiency, cause the intersection of eyes and aggravation of feeling of fatigue, appear eyes do, eyes itch, burn the intersection of foreign matter and sense, look at the intersection of thing and fuzzy, the intersection of eyesight and drop, the intersection of eye and bloated pain, the intersection of eye socket and the intersection of person who ache and symptom, the patient might present the near-sighted degree and increase, use and look at situations such as tired syndrome,etc. yet.
