可以调焦的眼镜?

They may look like an ordinary pair of spectacles, but these glasses are at the forefront of a revolution in eyewear.
它们看起来像普通的眼镜，但是是眼镜改革的最前沿。

Part of a new line of electronic eye glasses called emPower, they allow bifocal wearers to switch between different prescription settings for reading and more distant viewing.
电子眼镜一个新的部分是enPower，允许双焦眼镜对看书和更远景观的不同指令调节点进行转换。

emPower spectacles contain the world's first electronic focusing lenses.
emPower眼镜含有世界第一的电子聚焦透镜。

The lenses contain a thin layer of liquid crystal that changes its alignment when prompted, thereby changing the strength of focus.
镜片中含有一层薄的液晶层，给提示时可以改变它的定位。

People who wear bifocal glasses know all about how the distorted view they get when looking downwards at the ground.
戴双焦眼镜的人知道往地下看的时候怎么是看到歪曲的景象。

All the emPower wearer needs to do is tilt his head downward or manually touch the frame and the reading prescription is activated - and vice versa.
emPower眼镜所需要做的就是将其最前部向下倾斜，或者用手触碰一下，那么镜框的读数指令就被激活——反之亦然。

emPower manufacturer PixelOptics promises the new glasses will be 'fabricated in all prescriptions... and will be available in numerous high-fashion styles, shapes, sizes and colours'.
emPower制造商PixelOptics承诺这个新型眼镜将“创造所有指令”……并且适用于各种最新风格，形状，尺寸和颜色。

The glasses were unveiled last month during the International Vision Expo East in New York and are set for a U.S. release this summer.
这种眼镜上个月在纽约美国东部国际眼镜展览会上展示，并准备今年夏天上市。

Each eight-hour battery charge allows for two-to-three days of switching between focus settings.
每次充电8小时可以转换调焦设置两到三天。

The frames have three settings - automatic, manual on and manual off - allowing the wearer to remain fully in control.
镜框有三个按键设置——自动，手动开和手动关——让佩戴者可以完全控制。

One potential drawback is their cost - a pair will set you back between $1,000 and £1,250, although that includes the frames, lenses , coatings and charger.
这种眼镜的一个缺点就是价格—买一副眼镜要花你很多钱，1000美元到1250美元之间，尽管那个价钱包括镜框，镜片，涂层和充电器。

PixelOptics has been developing its emPower glasses for 12 years and has filed 275 patents in the U.S. during the process.
PixelOptics发明emPower眼镜已经花了12年时间了，在这个过程中已经申请了275项专利。
