Do not watch if you want to keep your cool.

You can be as cynical as you want, but it's hard not to feel the emotions of Allen Zderad as he lays eyes on his wife for the first time in ten years.

Zderad suffers from retinitis pigmentosa, a degenerative eye disease with no cure. He has been completely blind for the last ten years, but thanks to a new system called Second Sight, part of his vision has been restored.

The system is pretty amazing. A microchip implanted in his eye receives signals from a camera mounted on his glasses and feeds it into his optic nerve, allowing him to see an extremely pixellated, black-and-white version of his wife's face.
