可以调焦的眼镜?

 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 prescription¹ 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 alignment² when prompted, thereby³ 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 downwards⁴ 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 tilt⁵ his head downward or manually touch the frame and the reading prescription is activated⁶ - and vice⁷ 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 prescriptions⁸... 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 fully⁹ 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。
