New approaches to vision with microchips holds out prospects for the blind

To date, chip-based retinal implants have only permitted a rudimentary restoration of vision. However, modifying the electrical signals emitted by the implants could change that. This is the conclusion of the initial published findings of a project sponsored by the Austrian Science Fund FWF, which showed that two specific retinal cell types respond differently to certain electrical signals – an effect that could improve the perception of light-dark contrasts.
