On contact lenses - eye specialist, please see the following article, he said, is that true? Soft contact lenses ─ the medical profession a conspiracy? ! I looked shocked, okay I did not wear soft contact lenses. Myopia friends to see it. At present, the incidence of myopia in China more than 30%, while in high school students, the incidence rate of Brille more than one half, while the incidence among college students as high as 70%! To solve this problem, there is a beautiful way to wear glasses: soft contact lenses soft contact lenses as a blockbuster glasses, appeared in 1987 since the first cases of soft contact lenses, so far, all the Chinese around tens of millions of human cases of this soft contact lens wear. To make soft contact lenses in patients with satisfactory short-term vision, which attracted thousands of young men anxious to looking beautiful. However, these people, most are ignorant of this product, while many businesses in an optical shop and eye center, why are there so many doctors with glasses? Why is lying so good do not wear soft contact lenses? Have been a few months ago, I did figure out it is a conspiracy! Soft contact lens is the largest of this century the medical profession a conspiracy! I have a friend in 1992, with the eye in the national characteristics of a very famous optical shops with a soft contact lens wearBrillen before the adoption of all the visual eye examination and test results for all normal, the cornea topographic maps have not found any abnormality, I have a friend who wished, with 650 degrees askew to the soft contact lens, but a month ago, my friend actually found their eyesight sharp regression, corneal thinning; corneal insensitive; also great papillary conjunctivitis, the eyes grow Each and raised inside the particles. And serious corneal edema, corneal neovascularization response and allergic reactions. Eye specialists said her corneal endothelial cell density equivalent to 60-year-old. Later to another hospital, said her ophthalmologist corneal endothelial cell density is quite thin. Serious damage to the cornea has to be corneal transplantation. The donor cornea is very tight, my friend who is feeling now living death. To know that my friend is only 30 years old ah, now waiting for her husband and her divorce. Her surgery, I learned that a famous eye hospital in surgery, to see her: she is very, very remorse, regret was wearing soft contact lenses, and now spend huge position, replacement of the cornea to endure pain, but also do not know what will happen after replacement? Later, I consulted several ophthalmologists, ophthalmic knowledge for only about a 12, the following experts, I will answer eye summarized as follows: 1. Soft contact lens corneal stop breathing, corneal cells are transparent, there is no vascular supply oxygen. Transport of oxygen through the tears to the corneal cells. Contact lens and cornea of the need for a thin layer of tears, blinking at each time will produce some tears in the exchange, so that the tears ran out of oxygen in the middle of Brillen online contact lens and cornea, providing fresh oxygen to the cornea. Soft contact lenses are very close together to closely aligns the cornea does not move, no such tear exchange rate, so that the cornea can not be oxygen, eye corneal hypoxia may therefore, not normal metabolism, resistance decreased. Tear exchange to not wear soft contact lenses 10% of the time. Simply is not enough corneal breathing. Long continue, will produce corneal disease. Experts say: use contact lenses, hard contact lenses must use AA. AA Hard of tears because of the exchange is 95% when not wearing. AA rigid contact lenses of a ship floating in tears outside the membrane of the cornea. Each blink, AA rigid contact lenses can be moved up and down up to 1-2 mm. AA rigid contact lenses and corneal tear the middle of the exchange is full, can get enough oxygen in the cornea. So to tell patients to use AA rigid contact lenses, soft contact lenses can no longer was. He said the foreign soft contact lenses with a few people that have been eliminated, while China, only a year & Trade Co., Ltd. Dalian Hiroaki, State Drug Administration made hard contact lenses AA production license, do not know whether the production . So the market is hard to get.
