The birth of your child, the time you met the love of your life, the last memory you have of your grandmother... You stare at them hoping to make a lasting impression in your memory. But memories fade with time. Digital recordings, not so much. If Sony has anything to say, you will soon be able to record and even play back video of your favourite moments simply by blinking, while wearing smart contact lenses.

The Japanese tech giant filed a patent for what it describes as "a contact lens and storage medium capable of controlling an image pickup unit provided in the contact lens." It doesn't go as far as The Final Cut (2004), where people had their entire life history recorded with their memory implants, but users would, should this technology see the light of day, be able to take photos by blinking and upload them to a smartphone using wireless technology. 

In the patent description it says that the smart contact lens would be able to tell apart conscious from unconscious blinking and offer similar features as current smartphone cameras, such as zooming in and out or focusing. The product would have internal storage and the ability to re-play the footage, which means that the user could simply close eyes and re-live those favourite moments - over and over again, if one so wishes. Oh, now who wouldn't want to be able to do that?

As mentioned before, Sony is not the only player - remember Samsung and Google filing similar patents? We're very excited to see what the future brings!
