你可曾防备过那些领有蓝色眼睛的东说念主？要是有契机让眼睛历久酿成蓝色，你欢欣吗？好意思国加州的一家医学公司推出了一项新激光手术白石茉莉奈种子，只需20秒就不错让眼球酿成蓝色。

Blue eyes have historically been a significant measure of attractiveness， and although they’re commonly found among actors and models， only 17% of the global population has them. For the majority of people， approximately 80% of the population， blue eyes have been attainable only with the aid of colored contact lenses or artificial iris implants. But that will soon change with the introduction of a new medical procedure， pioneered by California company Stroma Medical， that can turn brown eyes blue. 蓝色眼睛一直被合计是好意思貌的一个艰巨计算圭表。尽管许多演员和模特皆有蓝眼睛，然则从巨匠限制来看，唯独17%的东说念主口领有蓝眼睛。对大多量东说念主（80%）而言，蓝色眼睛只可靠率领有色隐形眼镜或植入东说念主工虹膜来收尾。不外，这一切很快就要更正了，好意思国加州基质医学公司最初引进的一项生人术不错让棕色眼睛酿成蓝色。

The laser procedure works by eliminating the melanin from the surface of the iris， which then allows light to enter and scatter in the stroma. The effect is similar to Rayleigh scattering， in which wavelengths of sunlight hit much smaller molecules in the air and then scatter， which makes the atmosphere appear blue. 这项激光手术通过排斥虹膜名义的玄色素，让光辉得以插足虹膜，散播在基质层上，从而让眼睛呈现出蓝色。这照旧由和瑞利散射的道理访佛，当阳光的波长波及空气中的分子散射开来，太空就会呈现蓝色。

“The fundamental principle is that under every brown eye is a blue eye，” Dr. Gregg Homer told CNN， adding that there is no actual blue pigmentation in the eye. “The only difference between a brown eye and a blue eye is this very thin layer of pigment on the surface. If you take that pigment away， then the light can enter the stroma — the little fibers that look like bicycle spokes in a light eye – and when the light scatters it only reflects back the shortest wavelengths， and that’s the blue end of the spectrum.” 格雷格•荷马大夫告诉CNN说：“基本道理是，每只棕色眼睛的背面皆是一只蓝色眼睛。”他补充说，其实眼睛里并莫得蓝色的色素。棕色眼睛和蓝色眼睛的惟一分袂就在于虹膜名义的这层极薄的色素。要是你把这层色素移去，光辉就不错插足到基质层——这层纤维肌在淡色眼睛中看起来就像自行车辐条——当光辉散播到基质层上，唯独波长最短的光辉会反射且归，也等于光谱中的蓝光。”

The laser treatment disrupts the fragile layer of pigment on the iris， which causes the body to start removing the tissue naturally. While the procedure itself only takes around 20 seconds， the blue eyes do not emerge for several weeks， as the body can only gradually release the pigment. 激光手术会落魄虹膜名义这层脆弱的色素，促使东说念主体当然地移除相干组织。尽管手术自己只需20秒钟，然则要过上数周，眼睛才气酿成蓝色，因为东说念主体只可慢慢地开释色素。

Stroma Medical aspires to develop the safest， cheapest， and most convenient procedure available on the market， but it has yet to gain approval from the regulatory bodies in the United States. The company’s medical board has stated that preliminary studies show that the surgery is safe， but so far only 37 patients altogether have undergone the treatment. 17 patients were in Mexico and the remaining 20 in Costa Rica. The company is currently in the fundraising stage as it searches for investors， but hopes to have completed clinical trials within a few years. Currently， the price to change brown eyes blue stands at a relatively high amount of $5，000. 基质医学公司昂然研发出市集上最安全、最实惠、最便捷的眼球变色手术，但仍需得到好意思国监管机构的许可。该公司的医务委员会宣称，前期商榷透露，手术是安全的，但到当今限制所有唯独37位患者经受了这种手术。17位患者在墨西哥，其余20位在哥斯达黎加。该公司当今正在融资阶段，在寻找投资东说念主的同期，公司但愿简略在几年内完成临床磨真金不怕火。现时把棕色眼睛酿成蓝色眼睛的手术用度较高，需5000好意思元（3.3万元东说念主民币）。

The medical industry， ophthalmologists in particular， has not been particularly receptive to the procedure. The skepticism is based on the fact that eyes are one of the most sensitive organs in the human body， and that the procedure is irreversible. 医学界尤其是眼科界对这种手术的经受度不是止境高。他们质疑的依据是，眼睛是东说念主体最明锐的器官之一，而这种手术是不成逆的。

Saj Khan， an ophthalmologist at the London Eye Hospital， told CNN， “The primary concern with any procedure that involves releasing pigment inside the eye is that the pigment can clog up the regular drainage channels which can， in turn， cause the pressure inside the eye to go up. If that happens significantly enough， for long enough， it’s how patients develop glaucoma.” 伦敦眼科病院的眼科大夫萨吉•可汗告诉CNN说：“任何会开释眼内色素的手术让东说念主惦念的庞杂问题是，色素可能会堵塞微轮回，从而导致眼压上涨。要是情况严重何况历久合手续的话白石茉莉奈种子，就会患上青光眼。”

Stroma Medical claims that the particles released by the procedure are too small to cause glaucoma， which Khan admits makes sense， but he and other doctors are reluctant to recommend it. 基质医学公司宣称，手术所开释的微粒体积很小，不会导致青光眼，尽管可汗承认这种说法有道理，然则他和其他大夫如故不肯意推选这种手术。

“Theory has some sense to it， but without seeing long-term outcomes and without seeing patients that have been treated in this way I wouldn’t commit myself to it，” Khan said. 可汗说：“从表面上说是合理的，然则没看到历久效果，战争不到经受这种手术的患者，我是不会认同这种手术的。”

“It’s not a goal of our company to promote blue eyes，” Stroma Medica’s Dr. Gregg Homer told CNN. “From my experience what most people are after is the translucence of the blue eye rather than the color of the blue eye. The people who seem most vigilant about pursuing this always have a story about being young and in the presence of a sibling or a friend who had light eyes and the friend is being told how beautiful their eyes are， and it sticks with them. That seems to be something they’ve carried around with them. Would it be better for them to get over it? Probably. All your problems don’t go away because you’ve changed your eye color， but I do believe that people like to express themselves a certain way and it’s nice when they have the freedom to do that.” “咱们公司的谋略不是宣传蓝眼睛，”基质医学公司的格雷格•荷马大夫告诉CNN说，“凭据我的造就，多量东说念主追求的是蓝眼睛的澄莹感，而不是蓝眼睛的心思。那些最渴求蓝眼睛的东说念主频频皆有一个这么的故事：小技术某个昆仲姐妹或一又友领有蓝眼睛，然后被别东说念主奖饰眼睛很漂亮，于是他们就有了挥之不去的‘蓝眼睛情结’。是不是等他们我方放下这个执念会更好呢？很可能是这么。你自身的问题不会因为你更正了眼睛心思就完全散失，但我礼服有东说念主会欢欣用某种方式来抒发我方，让他们得到抒发的目田不是很好吗？”

东说念主类的眼睛究竟有些许种心思？

大色哥导航

东说念主类虹膜的基色唯独三种：褐色、蓝色和绿色。其他心思的虹膜则是这三种心思的变体。

褐色或棕色是最常见的东说念主类虹膜心思。中国东说念主险些99.99%的眼球皆是深棕色。

蓝色眼睛是除了棕色眼睛除外最多的一种心思。北欧东说念主如冰岛东说念主、芬兰东说念主和拉脱维亚东说念主约80%以上为蓝色眼睛。

灰色被合计是蓝色虹膜的变种，非常额外，留心大利、希腊等南欧国度出现的概率略高。

金色眼睛和灰色眼睛相似，是基因突变的居品。金色眼睛在好意思国出现的概率最高。

绿色虹膜亦然很荒凉的心思。在瑞士、波兰、乌克兰和白俄罗斯这些地区比例较高。

琥珀色在其他动物上较为常见，它比棕色更浅，很少在东说念主类出现，又被称为猫眼色。琥珀色在欧洲比拟多见，多为混血儿。

最荒凉确当属紫色眼睛，止境是深紫色眼睛。传闻领有紫色眼睛的东说念主，皆会长得非常漂亮，而伊丽莎白·泰勒就所以紫色眼睛知名的。（集聚概述整理）
