相机取景器看不清

If you don’t have 20/20 vision, you don’t need to worry about wearing your glasses or contacts when you use your camera. If it’s a DSLR or mirrorless camera, you’ll be able to adjust the power of the viewfinder to better match your eyes.

如果您没有20/20视力，则无需担心在使用相机时戴眼镜或隐形眼镜。 如果是DSLR或无反光镜相机，则可以调整取景器的功能以更好地匹配眼睛。

Beside the viewfinder is a little dial called the diopter-adjustment dial. This adjusts the power of the viewfinder and lets you tweak things so that whether you’re long- or short-sighted, things will look right to you.

取景器旁边是一个称为屈光度调节拨盘的小拨盘。 这可以调整取景器的功能，并让您调整事物，以便无论您是近视还是近视，事物都会看起来对您而言。

By default, the diopter-adjustment dial is set for 20/20 vision. You’ll know it isn’t set correctly for you if, when you look through the viewfinder, the information displayed is blurry or if your camera keeps telling you focus is good when the image still looks blurry—at least to your eyes. Also, if you’re manually focusing, you’ll find that your images are just out of focus when you review them later.

默认情况下，屈光度调节拨盘设置为20/20视力。 如果当您通过取景器查看时显示的信息模糊，或者当图像仍然看起来模糊时(至少在您的眼中)，如果相机一直告诉您对焦良好，您会知道它的设置不正确。 另外，如果您手动对焦 ，则稍后查看它们时会发现您的图像刚刚失焦。

Adjusting the diopter is a trial and error process. There usually is a slightly larger mark to indicate the center of the adjustment dial so you can easily reset it back to normal.

调整屈光度是一个反复试验的过程。 通常会有一个稍大的标记来指示调节拨盘的中心，因此您可以轻松地将其重置为正常状态。

The best way to know when you have the diopter set correctly is when the information displayed in the viewfinder looks sharp. If it’s easy to read, then the viewfinder should accurately show the scene in front of you. Twist the diopter-adjustment dial back and forth until you find the setting that works for you. It may be easier to remove the viewfinder cup so you can turn the dial.

知道何时正确设置屈光度的最好方法是在取景器中显示的信息清晰时。 如果易于阅读，则取景器应准确显示您面前的场景。 来回扭动屈光度调节拨盘，直到找到适合您的设置。 取下取景器杯可能会更容易，因此您可以转动拨盘。

Adjusting the diopter just affects the viewfinder—whether optical or electronic; you will still need to wear your glasses to focus with the Live View screen.

调整屈光度只会影响取景器， 无论是光学的还是电子的 。 您仍然需要戴上眼镜才能使实时显示屏幕聚焦。

Finally, the diopter-adjustment dial doesn’t lock into position. If things start looking blurry again through your camera, there’s a good chance that you accidentally hit the dial at some point. Adjust it again.

最后，屈光度调节拨盘不会锁定到位。 如果您的相机又开始出现模糊的情况，则很有可能在某个时候不小心按下了转盘。 再次调整。
