Blurry, unclear, unfocused vision is the most common eyesight problem, and usually it isn't anything major to worry about it. Blurriness could just be a sign that your glasses or contacts prescription needs updating. Every once in a while though, fuzzy vision signals something more serious.
视力模糊、不清晰、无焦距都是最常见的视力问题,通常都不需要太过担心。视力模糊可能是换眼镜或隐形眼镜的一个迹象。但有时候,视力模糊却是某些更严重问题的迹象。

Nearsightedness (myopia), farsightedness (hyperopia), and astigmatism are refractive errors and are the most common causes of blurry vision. The retina processes light rays into signals the brain can read.
近视、远视和散光都是屈光不正,也是视力模糊的最常见原因。视网膜会将光线处理成大脑可读取的信号。
In addition to being widespread, refractive errors may also be the easiest to fix. In most cases, all you need is a prescription from an optometrist or ophthalmologist for glasses or contact lenses. LASIK laser surgery can permanently change the shape of the cornea to correct the problem in some people.
除了十分广泛之外,屈光不正也是最容易矫正的。大多数情况下,你只需要验光师或眼科医生给你开一副处方眼镜或处方隐形眼镜。LASIK能永久改变角膜形状,以矫正一些人的屈光不正。
