可以調焦的眼鏡?
They may look like an ordinary pair of spectacles, but these glasses are at the forefront of a revolution in eyewear.
它們看起來像普通的眼鏡，但是是眼鏡改革的最前沿。
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.
電子眼鏡一個新的部分是enPower，允許雙焦眼鏡對看書和更遠景觀的不同指令調節點進行轉換。
emPower spectacles contain the world's first electronic focusing lenses.
emPower眼鏡含有世界第一的電子聚焦透鏡。
The lenses contain a thin layer of liquid crystal that changes its alignment when prompted, thereby changing the strength of focus.
鏡片中含有一層薄的液晶層，給提示時可以改變它的定位。
People who wear bifocal glasses know all about how the distorted view they get when looking downwards at the ground.
戴雙焦眼鏡的人知道往地下看的時候怎麼是看到歪曲的景象。
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眼鏡所需要做的就是將其最前部向下傾斜，或者用手觸碰一下，那麼鏡框的讀數指令就被激活——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製造商PixelOptics承諾這個新型眼鏡將“創造所有指令”……並且適用於各種最新風格，形狀，尺寸和顏色。
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.
這種眼鏡上個月在紐約美國東部國際眼鏡展覽會上展示，並準備今年夏天上市。
Each eight-hour battery charge allows for two-to-three days of switching between focus settings.
每次充電8小時可以轉換調焦設置兩到三天。
The frames have three settings - automatic, manual on and manual off - allowing the wearer to remain fully in control.
鏡框有三個按鍵設置——自動，手動開和手動關——讓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.
這種眼鏡的一個缺點就是價格—買一副眼鏡要花你很多錢，1000美元到1250美元之間，儘管那個價錢包括鏡框，鏡片，塗層和充電器。
PixelOptics has been developing its emPower glasses for 12 years and has filed 275 patents in the U.S. during the process.
PixelOptics發明emPower眼鏡已經花了12年時間了，在這個過程中已經申請了275項專利。
