Recent technological improvements have allowed further miniaturisation of electronic components.

This has allowed the implantation of devices that can replace the initial photoreception by rods and cones in patients with absence of these cells from disease.

Artificial vision is also needed for independently mobile machines.

Understanding the human visual system has also led to improvements of robot navigation. For instance programming robots with visual illusions improves their performance in complex environments.

Seeing robots and blind patients with artificial vision are already a reality. Truly amazing inventions are just steps away. What was thought impossible ten years ago is now commonplace. What will the next yen years reveal to us?
