Rob Spence lost the use of his eye following a shooting accident when he was nine.
But decades on, the Canadian documentary maker had the idea of replacing the eye with a camera.
"Literally everybody [said] it as a joke - ‘Oh, you should get an eye camera'.
"The two reactions are, ‘Wow, that’s so cool’ — and, after a few moments’ reflection, ‘But that’s so creepy'.
“I’ve actually started wondering, do we want to have constant video of our lives? It’s just another data set. And I don’t know the answer, but I think no, we don’t want that. But it’s coming anyway."
Spence cannot see out of the lense but a what the 'eye' can see is visible from a handheld monitor.
