近视的人游泳会不方便吗？
是的，近视眼的人可以到游泳商店去买对于近视的游泳者专门针对的，近视游泳镜。你可以在那里挑选你带着合适的近视泳镜。至于怎么游泳嘛，要是初学者的话就要从基础的学起初学者要从最基础的开始学起: 学者下水之后就得要在水里面做做呼吸，抬头嘴吸气，水中鼻子出气，以后防止呛水。之后，要学习漂浮。漂浮练习最后可以是旁边有个人用双手轻轻的拖起练习人的身体，当他身体浮起水面后，再松开手让他自己找感觉。旁边没有也可以找漂浮板放在腰或屁股的位置上，慢慢的浮起。这是最基本的练习方法。 学会了漂浮，就可以学其它的项目了，碟 仰 蛙 自 四项

，但是价格不菲。。就是肯定不舒服是了，因为隐形眼镜很容易携带细菌）。。。。如果近视的不算厉害。也可以购买或订做有度数的游泳镜。。。实在不行也有用松紧带把框架眼睛绷在脸上的。。。能看清前面横着的是大腿和脚巴丫不会撞上去就行。。，可以将就着游可以佩戴隐形眼镜然后戴上泳镜（要注意不要水渗进去

不会啊~~~可以游泳的时候不带眼睛哦如果你度数太高了 可以带着眼睛游 没关系的
戴上隐形眼镜后再戴泳镜
不会啊,但是不能戴隐型眼睛.其实不带眼睛也OK啊,反正是在水里面嘛,无所谓拉.除非你是高度近视
近视真,,,,,
当然会喽!如果游泳的时候不小心撞到了怎么办?????

为什么近视的人喜欢眯眼睛？眯眼睛有哪些危害？
参加活动: 0

大家都知道，近视眼如果不佩戴眼镜的话，看东西的时候都喜欢眯着眼睛。
近视眼是指看近处清楚而看远处不清楚的一种病理状态。属于一种屈光不正，视物通过眼球屈光系统的折射，无法汇聚在视网膜上，因此不能在视网膜上形成清晰的像。一般认为，非遗传性近视形成的主要原因是过度地阅读及其它的近距离活动给眼睛带来的过度的调节负担，长时间近距离使用眼睛，睫状肌会痉挛，暂时失去放松的能力，造成视物不清，从而形成假性近视。如果长此以往，痉挛的睫状肌可能刺激眼球前后轴的拉伸，进而造成无法逆转的真性近视。

当近视眯起眼睛看事物的时候，眼睛就可以对光线的入射起到限制的作用，从而减少像差，能让自己看得更清楚一些。长期眯着眼睛看事物，会导致眼部肌肉的疲劳、紧张，会使眼睛近视度数加深得更快。
往往近视眯眼睛会成为习惯，看远处的时候不自觉的就眯起眼睛，其实近视后要看清远处，最简单的方法就是佩戴眼镜。因此，有眯眼习惯的患者，应该马上改掉这个坏习惯，及时到正规的眼镜连锁店或者眼科视光中心检查，配上一副适合你自己屈光度的眼镜，以免造成以后眼睛屈光度的加深。

近视不戴眼镜眯眼睛都有哪些危害：
1、眼睛更容易疲劳总是喜欢眯着眼睛看东西，虽然是看得更清楚了，但是其实更费力了，长时间这么看，眼睛更容易疲劳，尤其是上学的学生，本身学习压力就比较大，如果总是眯着眼睛看东西，那么视力下降的速度会越来越快。
2、加深近视原本已经近视的眼睛，如果配的眼镜度数不符，或者习惯性的眯着眼睛，那么在不知不觉中你就已经让眼睛的近视度数变得越来越高，这就是为什么很多孩子明明已经配好了眼镜，度数却还是不断加深。

3、可能眼睛有散光眯眼睛是通过物理学上的针孔效果和裂隙作用，可以在一定程度上提高视力，因此散光患者看远时常眯眼，戴镜后即能矫正这种不良习惯。需要说明的是，眯眼并非散光眼固有的表现，它也同样可发生于近视患者。

英国眼科专家表示，大眼睛的人更容易得近视眼。专家指出，近视眼是由于外界光线焦点没有正确落在视网膜上而造成的，大眼睛的人因为眼球太大而导致外界光线焦点没有落在视网膜上，而是落在视网膜前方，因而无法在视网膜上形成清晰的图像。与此相反，眼睛小的人更容易得远视眼，也就是外界光线焦点落在视网膜后方。
Rebecca Large has always been told her big brown eyes are her best feature. Like those of Hollywood stars Angelina Jolie and Audrey Hepburn, Rebecca's eyes are regarded by most as a sign of beauty.
Yet eye experts have realised that far from being an asset, large eyes can actually be a weakness, and make someone more
to being short-sighted.
This condition, also known as myopia, causes distant objects to appear , while close ones can be seen clearly. It is caused by light not properly reaching the retina（视网膜）, the light- sensitive area at the back of the eye.
Experts believe this might be because the eyeball grows too large, which causes the light to focus in front of the retina, rather than on it.
Short-sightedness is on the rise in Britain, with up to 50 per cent of people now estimated to have it.
One possible explanation for this is that our eyeballs are getting larger because we are spending more time indoors. A lack of outdoor light in our early years causes the size of the eyeball to increase. But the larger the eyeball, the more likely a person is to be short-sighted, explains Andy Luff, a
ophthalmic（眼睛的） surgeon at Optegra, a chain of private eye hospitals.
'While big eyes can certainly look beautiful, the fact is that if your eyes are slightly too big, this will cause you to suffer short sight. If the eyeball is too big, the light focused by the lens of the eye does not reach the back the retina, where images are processed.
'If the eye is only 1&mm longer than 24&mm (the average size from front to back) a person will be significantly short-sighted. Longer than the average by 2 to 5mm will make you highly short-sighted.'
Dr Luff explains that in the past we thought the eye grew too large and became short-sighted due to
'Although genetics is still the most important reason behind short-sightedness, lack of exposure to outdoor light is another possible cause. And it's the one preventable cause which can be addressed in childhood.'
Our eyes usually reach their full size by our 20s. The ideal is that they stop growing at the right size and will have perfect vision, but if they grow too big they'll be short-sighted and if they don't grow enough they're long-sighted, and won't be able to see things close up. Some children can have eyes that are too large by the age of five, says Dr Luff.
A review published by the University of Cambridge in 2011 found that for each additional hour spent outside each week, the risk of short-sightedness was reduced by 2 per cent. The review of studies involving 10,000 children and adolescents found that short-sighted children spent on average 3.7 fewer hours per week outdoors than those with normal vision or long-sightedness.
But how could exposure to light change the shape of the eyeball? Dr Saunders suggests that natural light in the eyeball
a type of biological switch that prevents it from growing too large. However, artificial light is not strong enough to
this switch.
People with small eyes tend to be long-sighted and will have difficulty seeing close objects clearly because light rays are focused behind the retina.
But this tends to be largely genetic. 'Too much outdoor light will not make your eye long-sighted,' says Mr Luff. He adds that short-sighted people seem to suffer more complications than those who are long-sighted.
'We see far more associated eye health problems in the short-sighted than the long-sighted, so it's worth doing everything you can to try and prevent it,' he explains.
However, Dr Susan Blakeney, clinical
to the College of , says there could be other factors contributing to why our increasingly indoor lifestyles may be causing bad eyesight.
'We still don't know what it is about time spent outside that has a protective effect against short-sightedness - it could be the sunshine, the brightness of the light or the fact that objects you focus on tend to be farther away outdoors.'
In rare cases short-sightedness can also be caused by the curve of the cornea（角膜） (the
part of the front of the eyeball) being too steep.
