The myopia crowd had better not wear the contact lenses to exchange oxygen deficiency of eyes
Are there near-sighted persons that choose to wear the glasses or wear the contact lenses? No matter what is chosen, wear the contact lenses everybody should be cautious.
Miss Qiu in Beijing has caught a cold recently, she finds behind taking cold drug it is astringent and uncomfortable to especially does the eye, can't go to work normally. Do not know to be caused by contact lenses until the hospital check. How does cold have relationships with the contact lenses? What it is about this on earth?
The People's Hospital ophthalmology associate professor of treatment Li MingWu of Peking University explains, nose and eyes pass the connectivity of nasolacrimal duct, people it is very easy to transmit bacterium and virus to the eye through this passway at the cold, cause and infect. In addition the intersection of eyes and conjunctiva organize too often with inflammation at the cold, wear contact lenses have a fever, the sense of eyes foreign matter is more obvious, will bring out or aggravate inflammation of eyes in this way. Meanwhile, patient's resistance drops, pluck it in the course of wearing the contact lenses during cold, the germ is very easy to pluck and wear movements to enter eyes and result in infecting at the same time.
The question of wearing the contact lenses and bringing is far above so. It still can let the intersection of eyes and oxygen deficiency, serious the intersection of people and cornea will be lossed.
Ophthalmology department chief physician Zheng GuiHai of children's hospital in Fuzhou says, the oxygen that the eyeball needs has 85% to exchange through the cornea from side to side, and the contact lenses are closely affixed to cornea, influence this kind of exchange, make angiectasis of eye, blood support difference is apt to cause skin loss on the cornea. And the cover takes off the backwardness on the cornea, the eye will increase greatly when being infected with the chance of germ, bacterium,etc..
Director Zheng says, in the former clinic, often find the person who wears contact lenses suffers from bacterial keratitis and protozoacide keratitis. * amebic protozoacide exists in the nature extensively, in a situation that the skin has the wound on the cornea, it is very easy to result in infecting to contact the pathogen. Symptom of this kind of disease varies with each individual, if does not treat in time, some patients may even need to accept the cornea and transplanting and there is blind possibility.
Director Zheng reminds, is not merely a cold patient, even a healthy crowd, if wear the glasses, had better choose the frame glasses. Especially try not to wear the contact lenses during cold. If the special circumstances need wearing, should reduce and wear time, pay attention to reading the medicine manual while choosing cold drug, see whether to mark the words that can lighten and shed tears symptom, avoid this kind of medicine as much as possible.
