. - According to the Huffington Post, Sony filed a patent for contact lenses that can take pictures and record video.
The wearer operates the contact lenses by blinking.
The lenses do not have to be linked to a smartphone or other outside device.
Not only can they store pictures and video, the lenses can play them back for the wearer.
It seems like it will be extremely hard to tell if some is wearing these video recording contact lenses.
Many privacy experts say it could leave people vulnerable to being recorded without their knowledge or consent.
Google is working on manufacturing similar technology.
