Man fitted with first-ever bionic eye, sees wife for the first time

James, blind in his left eye and with limited vision in his right, received a bionic eye implant. A microchip with 1500 electrodes was placed beneath his retina, converting light into electric signals sent to the brain. The chip is powered by a battery pack and supported by an external device for image processing. Three weeks after surgery, James regained basic vision, allowing him to see his wife for the first time.

How does the microchip convert light into signals?

What was the outcome for James three weeks after the surgery?
