Sheryl Berman, M.D., a medical officer in the FDA's Division of Ophthalmic and Ear, Nose, and Throat Devices, says that wearing sunglasses reduces the risk of eye damage due to sun exposure, but doesn't completely eliminate it.

"Even when we talk about 100 percent UV protection, light still enters from the sides of sunglasses and can be reflected into the eye," she says. Some people choose sunglasses that wrap all the way around the temples. A hat with a three-inch brim can help block sunlight that comes in from overhead.

枫下沙龙 / 时尚 / 姐妹们，请教一下哈，我高度近视眼，想买一副看起来漂亮点的太阳镜夹片，哪里有卖啊。看着姐妹们带着酷酷美美的太阳镜我好羡慕。 -carol2010(静待佳音); 2010-8-28 (#6249537@0)

我也戴眼镜，我的眼镜都是在costco配的，直接要的带clip的镜框。我觉得比那种单独买的好，形状和大小和你的眼镜架完全吻合。就是选择不多。不过，单独买的，选择也不多。 -hhorse(hhorse); 2010-8-28 (#6249567@0)
costco有卖那种可以吸在眼镜上的墨镜片，挺方便 -zoomin(毛豆儿); 2010-8-28 (#6249766@0)
Clip on 的墨镜对眼睛不好，因为一般室内用的近视眼镜框都偏小。你夹上墨镜后，瞳孔放大了，但是光线从周边很容易射进来反而加倍伤害眼睛。你应该直接配近视的墨镜，选你喜欢的大大的框。 -kakashi(kakashi); 2010-8-29 (#6250392@0)

good to know. 那这样说需要always买大框架的墨镜喽。中高度数的近视眼还是会受限制，因为随着镜片厚度增加，眼镜重量会增加，而且容易出现中心和四周颜色不一致的问题。 -hhorse(hhorse); 2010-8-29 (#6250465@0)

我就是戴深度近视的墨镜，是比我室内的眼睛沉多了，框沉，镜片也没有做超薄，不过感觉还好，戴上了就忘了，有时候我都要摸一下才能反应过来我戴的是哪个。颜色的问题我没有感觉，应该是镜片质量的问题吧 -kakashi(kakashi); 2010-8-29 (#6250749@0)

哈哈哈，太搞笑了。瞳孔是根据光线自动调节的。带上墨镜瞳孔变大，光线从旁边进来多了，瞳孔又会变小。一般墨镜比较大是为了遮住眼睛周边的皮肤不受阳光伤害。 -exception(违例); 2010-8-30 {96} (#6251280@0)
用两副眼镜的坏处是，任何两副眼镜的屈光度，瞳距等参数不可能完全一样，换来换去的会使眼睛更加疲劳。

随便google一下就可以了解到的知识，能让你乐成这样。。。哎，做人做成你这样也挺有意思的。 -kakashi(kakashi); 2010-8-30 (#6251535@0)

特地花了半个小时Google，还真没找到你说的“知识”。反而找到一些文章说太大的墨镜对眼睛有危害。 -exception(违例); 2010-8-30 {416} (#6251804@0)
下面文字引用自网络：据哈医大一院眼科医院医生介绍，作为保护视力的太阳镜，并不是越大越好，因为人们的脸宽度是有限的，而太阳镜除了镜片的宽度，还要加上中间支架的横度。如果镜片过大覆盖在人们脸上时的弧度也会产生变化，一般情况下，10度弧度内是安全的。而镜片的弧度一旦超过15度，镜片接受光线的折射率就会出现变化，而镜面弧度越大折射率变化越大，佩戴这种太阳镜时，看到的事物就会出现凹凸不平，长期佩戴易使眼睛疲劳、干涩，损害视力。

不好意思，我英文比较差。请问您的转载里面那个单词跟“瞳孔放大缩小”有关？ -exception(违例); 2010-8-31 (#6254128@0)

其实我回完上贴就后悔了，各人自己的眼睛眼镜，爱咋咋地，懒得较这个劲。我不再废话了，你随意。 -kakashi(kakashi); 2010-9-1 (#6255017@0)

换成隐形眼镜? -youbet(寻常巷陌); 2010-8-29 (#6250459@0)

是呀，换成隐形眼镜就和视力正常的人一样随意选了。可惜我戴不了隐形。 -hhorse(hhorse); 2010-8-29 (#6250468@0)

每个人刚戴隐形眼睛的时候都特笨特难, 我刚戴那会戴和摘都得花半个多小时, 人家说95%的人都没问题, 我觉得自己一定是那5% :-) 现在戴和摘都是不到半分钟的事了. -youbet(寻常巷陌); 2010-8-29 (#6250783@0)

不能戴隐形的原因有很多，不一定是特笨特难。比如沙眼结石。 -exception(违例); 2010-8-30 (#6251281@0)

干嘛不配一付近视太阳镜？我在太古配过。 -haploidus(今剩叹); 2010-8-30 (#6251374@0)

我一只眼睛650，一只500，在太古能配到合适的近视太阳眼睛吗？我倒是考虑过隐形眼镜，试着带了几天，眼睛很难受，放弃了。 -carol2010(静待佳音); 2010-8-30 (#6251818@0)

和配普通近视眼镜没什么区别 -kakashi(kakashi); 2010-8-30 (#6252071@0)
没问题，度数深就别悬弧度特别大的墨镜，一般墨镜都可以，再单配个带度数的墨镜片即可。 -facenorthface(北脸); 2010-8-30 (#6252102@0)
我在国内配过，差不多跟你的度数，一只眼比你浅。 -sowen(昂居居); 2010-8-30 (#6252105@0)

现在流行的是“全视线”变色镜，可以根据室外紫外线强度自动调节眼镜的黑度。在室内就是完全透明，和一般眼镜一样，在晴天室外马上就变的很黑。回到室内，几分钟就变回完全透明。 -ding_ding(丁_丁); 2010-8-30 (#6252114@0)

哇，好高级耶。 -carol2010(静待佳音); 2010-8-30 (#6252126@0)
