Google has applied for a patent on new technology, digital can be directly into the user attention. Google for years have been developing smart glasses and smart contact lenses, but the company's latest patented technology will adopt more direct way to achieve similar functionality. Google in the last week said the United States patent and trademark office approved the patent document, they will remove the lens, the empty bag filling the liquid lens, then join in the liquid of electron lens.

Equipped with such a lens, no longer need glasses or contact lenses. Even no longer need the telescope and microscope, even take photographs and video camera can be thrown away.

This computerized lens can automatically adjust, help people see objects at different distances. The lens can get energy through eye movement, and even can be connected to the nearby wireless devices.

Google said that this technology can be used to treat presbyopia, also can correct the common vision problems such as myopia, hyperopia and astigmatism. Blurred vision we now correction with glasses or contact lenses, but sometimes, vision problems are still not completely correct.

Use of such electronic eye has obvious advantages. But Google pointed out that the privacy issues could become a concern. If this is always to transmit data, law enforcement and hackers can intercept signal, to judge the identity of the user, or a way to track user activity. But Google says, can be in electronic eyes to remove personal identity information and guarantee the security of data.

But it is important to note that Google and a number of technology companies are constantly apply for all kinds of technology patents, but many of them cannot become the finished product. So it is unclear whether Google will eventually implanted this is for the user.
