Macular degeneration steals the center of your vision. The light receptors die. But the wiring behind them? That stays perfectly fine. That one biological detail is the reason the PRIMA trial works. You do not need to replace the whole eye. You just need to plug a new input device into the surviving neural circuitry. Patients get a microchip implanted beneath the retina. They wear a pair of camera-equipped glasses. The glasses capture the world, convert it into infrared light, and beam it directly into the eye. The chip turns that light into electrical pulses that the optic nerve understands. In recent clinical trials, patients with severe vision loss regained the ability to read text. They process natural vision on the edges and digital vision in the center. The brain is still doing the seeing. The hardware is just translating.
