Then there's orthokeratology or Ortho-k lenses… hard contact lenses worn only at night that reshape the wearer's cornea while they sleep… so that they can see at a distance during the day.

然后是角膜塑形镜（Ortho-k），这是一种只晚上戴的硬隐形眼镜，可戴睡塑他们的角膜，这样他们就可白天看到远处的东西。

And then sometimes you get contacts so that or contact lenses so people don't know that you're wearing glasses.

有你会选择隐形眼镜或角膜接触镜，这样别人就不知道你戴着眼镜了。
