按着上边说法比欧洲晚了15年 Nightwear ortho-k solutions were available to consumers in many countries outside the US much earlier than within the US, due to international differences between regulatory controls and bodies. In 1994, the FDA granted the first ever daily wear approval for a lens indicated for Orthokeratology to a type of lens called the Contex OK-Lens. In June 2002, the FDA granted approval for overnight wear of a type of corneal reshaping called "Corneal Refractive Therapy" (CRT), more than fifteen years after Europe en.wikipedia.org/wiki/Orthokeratology 另外现在OK镜有不同方法设计,新技术eyespace ortho k 和 wave 其中的Find a Practitioner (eye.space)www.eye.space/nav-practitioner （从这些找医生里就能看出欧洲也有） 还有wave 技术设计的www.wavecontactlenses.com/patients#section-127-208（从这些找医生里就能看出欧洲也有） www.wavecontactlenses.com/ecp/products/orthok 最早是CRT 这家的 paragonvision.com/crt-lenses/ CRT效果没上边两种好根据我的研究。 这三种都属于OK镜
OK镜在佩戴期间的效果不错，但对于眼睛器官上的长期影响似乎并不清楚。或者说出问题的人的声音太小了，我们听到的都是好的，某种幸存者偏差。（不考虑使用OK镜期间的短暂感染问题，如果好好清洁，这个应该比较好避免）
想听听华人上有没有长期使用OK镜后来停掉，这期间有没有什么问题？

需要一直带，不戴反弹很厉害。 我从高中戴到大学毕业，出国后没戴，结果近视深了很多。不知道戴到30岁会不会好些
老有人说18岁之后就不会更近视了，然而并不是，我和认识的很多人都是三十多岁近视度数才稳定下来，我家娃的眼科诊所里不少大学生还在带ok，但是超过500度一般OK就不行了
反正我是不会给孩子戴这个。眼科医生很多也不支持ok 镜
我30了度数还没稳定…
个体差异。我8岁就二百多度了，到14岁也才三百多度，之后一直没变过。三十多做了lasik，也一直没变过。
是的，眼科医生也说30岁左右才能稳定
个体差异吧。初一近视后熬过初中高中六年度数也没变，而且只有看黑板才戴一会眼镜。成年后手机ipad各种关灯玩，检查也没加深。可惜娃貌似没遗传到😑😑
羡慕呀，我这眼瞅着奔四了度数才稳定
你们眼科医生这么牛吗，是眼科医生？还是就是验光师啊？
我四十+近视是不涨了，但是老花涨，还是觉得视力越来越差
他是ophthalmologist，专门研究小儿近视的。
你女儿是个例，很幸运。我身边太多三十多还近视加深的人了。眼科医生无一例外都反对ok镜，甚至misight，他们最推崇框架，唯一能接受的就是altropine。猜测是因为他们有selection bias，他们接触到的ok镜的患者全是带ok镜出现问题的人
我小表姐女儿小时候275度一直戴普通隐形度数也没涨，我想是不是框架眼镜老动来动去不稳会造成度数涨，戴在眼球上不容易动，反而不涨度数。 我一朋友孩子小学三年级OK镜子到大学度数也没变。
我也有这种感觉，身边带框架包括我自己度数涨的厉害，隐形或者ok的就还好，当然是小数据没有严谨的科学依据
Mysight不需要戴那么久吧？我还打算15岁就停了呢，否则要破产。
什么时候的事情，我朋友在欧洲，那边的医生不推荐OK镜和阿托品

眼科医生一般很少做OK镜，一般都是OD验光师的生意。 当然也有少数眼科医生做OK镜根据我当时搜索周围医生结果，那个眼科医生还是哈佛的开的诊所，但我研究是他诊所里验光师OD做，他自己MD并不做。他那个诊所属于有好几个医生外加几个OD验光师的大诊所。
天哪
是的，我以前的一个朋友就是那样
我问过大学做眼科研究的医生, 那是10年前， 最主要的是刮伤角膜， 晚上带contacts，眼睛细胞氧气不如不带的多，会引起细胞小血管增生(不过contacts越来越透气 应该risk越来越小)
眼角膜按说是可以很快修复好的
他们推荐啥？
眼睛这么重要，就算是小概率但是都导致眼科医生bias了也不想冒险吧
那跟戴普通隐形眼镜的区别是什么啊？普通隐形也要一直戴……
我四十多了，疫情期间还加深了两百度。
散光这个很难说，我老公不带OK镜也发展出了高度散光
我们娃打球，戴misight很方便。游泳可能麻烦点，但是有人说带眼镜罩没问题，游泳完了之后再换一副新的好了。
正经不创收的眼科专科医生连阿托品都不推荐，长期瞳孔放大，晶体和视网膜受到的紫外线增多加速老化，几十年后中老年会出现问题。说白了就是遗传加用眼时间，长时间近距离这一点不能纠正的话，OK镜之类的就是短期缓解家长心理焦虑的。
你说的是对的 长期阿托品会大大提高中老年青光眼的风险 唉
一种特殊的离焦镜，具体名字我忘记了。感觉OK镜和阿托品在中国美国澳洲比较流行，我之前还以为很好呢，毕竟美国医学还是全球领先，朋友和我说欧洲不推荐我还觉得欧洲太落后了吧，现在看这个楼里大家的回复，发现欧洲的医生还挺靠谱的
我觉得很多人没搞明白，戴Ok镜只是为了减缓眼睛加深的速度，并不是治疗近视。戴到18岁做激光或者戴正常隐形或者框架或者继续ok镜。我自己高度近视，很怕小孩遗传到，本来两个小小孩戴框架每6个月就深50度，这样下去怎么行，就开始戴ok镜，至少一个三年了一个两年了，度数维持得很好没有加深，他们也习惯了，运动什么也方便。所以如果有concern就不要戴，如果怕深的速度太快就戴。看自己情况了。不能笼统说好还是不好
可以佩戴有近视度数的游泳眼镜啊
