OK, this is bound to raise some red flags among privacy advocates, even more than Google Glass ever did. It is also going to make sci-fi aficionados drool and wish they would still be alive, not to mention capable of wearing this smart contact lens, when it actually becomes a product. Smart contact lenses are nothing new to our ears, but what Sony has tried to patent is incredible in both senses of the word: a contact lens that crams enough camera hardware to make it both useful and dangerous.
Before getting too excited or even too panicked, bear in mind that this is only a patent application. Sony might not even have the technology for it yet. But, at the very least, it is entertaining the possibility. Or is just jealously safeguarding the future against anyone who would actually have the ability to implement it.
