" A common misunderstanding is that a surgery can cure myopia, but in fact, the procedure can only remove the need for glasses, or apply the refractive function of glasses to the eyeball, " he said.

“目前最常见的误区是很多人都认为手术可以治愈近视，严格来讲，手术仅仅是‘摘镜’，也就是说，通过手术的手段，把眼镜的屈施加到眼球，让我们的眼球能够匹配过生长的数。

The device also has a diopter adjustment built in, so people who wear glasses or contact can use it without wearing additional vision correction.

该设备还内置了屈调节功能，因此佩眼镜或接触的人无需佩额外的视力矫正即可使用它。

Wei Wenbin, a senior ophthalmologist at Beijing Tongren Hospital, told a recent news conference that laser eye surgeries are recommended for people age 18 and above to ensure stable refraction, but rigorous pre-operation evaluations should be carried out.

北京同仁医院资深眼科专家魏文斌在最近的新闻发布会表示，建议18岁及以的人接受近视激手术，确保稳定的屈，但应进行严格的术前评估。

Diopter strengths are like most lenses measured in meters.

- 屈与大多数透镜一样，以米为单位进行测量。

So it's very important to have a kind of stable stand for it, and that they just borrowed from standard diopters, standard implements.

所以有一个稳定的底座非常重要，他们只是借用了标准屈和标准工具。

In cinematography, diopter is technically a misnomer for a close-up adapter.

- 在电影摄影中，“屈”是对近摄接圈的一个技术性误称。

While a one-half diopter will allow objects two meters away to be in focus.

而使用半屈（one-half diopter）的透镜，则能让两米远的物体保持清晰对焦。

The nondiopter part of the camera lens will need to have the farthest subject in focus.

相机镜头的无屈部分需要将最远的被摄物体保持在焦点。

With a plus one diopter objects, one meter away will be in focus.

使用正一屈的透镜，一米远的物体将处于焦点。

The ARRI SM B1, for example, has the ability to rotate a filter so that gradients or diopters can be angled, and it can swap sunshades for spherical versus anamorphic lenses for additional adaptability.

例如，ARRI SM B1遮盒能够旋转滤镜， 以便调整渐变或屈的角，并且它可以更换遮板以适应球面镜头和变形镜头， 从而提供更多的灵活性。

And before you start thinking about diopters, you'll need a movie to use them in.

- 在你开始考虑屈之前，你需要有一部电影来使用它们。

For example, if the focus of a lens is set at infinite, with a plus two diopter, the objects half a meter from the diopter will be in focus.

例如， 如果一个镜头的焦点设在无限远，使用正二屈， 那么距离该屈半米的物体将会清晰对焦。
