In Seoul, Korea alone, 97% of 19-year-old males need corrective lenses.

单单韩国首尔，19岁男性就有97%需要戴眼镜。

Anyway, before the invention of corrective lenses a few centuries ago, people who couldn't see just… couldn't see.

不管怎样，在几个世纪前矫正镜片发明之前，看不见的人只是… … 看不见。

Thanks to all of our patrons on Patreon, who probably have a higher than average number of corrective lenses among them.

感谢我们在 Patreon 上的所有赞助人，他们中的矫正镜片数量可能高于平均水平。

If we wear corrective lenses now, perhaps our vision could be improved or restored through laser surgery. We would no longer need to wear glasses.

如果我们现在带上矫正镜，或通过激光手术我们的视力就会改善或恢复。我们将不再需要带眼镜了。
