If you have an Eyephone，far from making your sight worse, the time you spent staring at a computer or iPhone screen could improve vision.
A brain-training app which is developed by US firm Ucansi that gives middle-aged people the eyesight of those ten years younger will be available to download within months, developers say.
They claim it can dramatically reduce the need for reading glasses in those who already wear them, as well as put off the day on which others need to invest in a pair.
Trials of the GlassesOff software have produced startling results, with people able to read more than two lines further down an eye chart after training. In addition, the time taken to read the page of a newspaper more than halved, New Scientist journal reports.
GlassesOff is expected to be launched early next year, initially as a smartphone app. A version for home computers could follow. It is said to combat presbyopia, or age-related long-sightedness.
The deterioration of eyes results from the stiffening of the eye's lens, which makes zooming in on close objects more difficult. This means the brain receives blurred information which it then struggles to process.
GlassesOff encourages the brain to make sense of this. People are first shown a grey screen containing a white circle, and then a number of images in quick succession at various places on the screen.
Some are blank, while others contain blurred patterns of lines, known as Gabor patches. The aim is to pick out any of the Gabor patches that fall in the same place as the white circle.
The task gets faster and more difficult as the person gets better at it.
Volunteers with an average age of 51 who took part in 40 training sessions found reading charts so much easier that their "eye age" was said to have reduced from 50.5 to 41.9 years. They were also four seconds a sentence quicker at reading.
Ucansi co-founder Uri Polat said:" The software is unlikely to do away with reading glasses. It may, however, reduce the amount of time people need to wear them. "



据英国《每日邮报》9月29日报道，如果你有一部"眼机"，那些你用来盯着电脑或iPhone 屏幕的时间将可能提高你的视力而不是使其变得更坏。
美国Ucansi公司研发出一套训练大脑的应用程序，它可以使中年人的视力恢复到十年前的水平。开发商表示，再过几个月，人们就可以下载它了。

他们声称，它可以显著地降低已经戴眼镜的人们对眼镜的依赖，同时也能推迟其他需要戴眼镜人购买眼镜的时间。

GlassesOff 软件的试用结果让人吃惊不已，接受训练过的人能多读两行视力检查表（上的内容）。另外，据《新科学家》杂志报道，（参与者）读报所用时间也缩短了一半。

GlassesOff 预计将于明年年初上市，最初作为智能手机的应用程序，随后将推出家用电脑的版本。据说它能对抗老花眼或和年龄有关的远视。


视力下降是因为眼睛晶状体固化，从而使人眼难以放大近处物体。这就意味着人脑接受模糊的信息并在努力地处理它们。

而GlassesOff 鼓励人脑意识到这点。研究人员首先向测试对象出示一个在灰色屏幕中的白色圆圈，紧接着在屏幕的不同位置将迅速出现大量图像。

这些图像有些是空白的，而其它的包含被称之为伽伯补丁的线条。训练的目的是让参与者选出那些落在和白色圆圈同一位置的伽伯补丁。

当人们任务完成的越好时，任务的难度和速度也就提升了。

那些平均年龄在51岁、参加了49节训练课的志愿者们发现，看视力表变得更容易了，他们"眼睛的岁数"好像从50.5年降到了41.9年，阅读一句话的速度也快了4秒钟。

Ucansi公司共同创立者尤瑞•波拉特说："这款软件不太可能代替老花镜，但是，它可能缩减人们需要戴老花镜的时间。"
