Vision is one of the most important senses we have as human beings — it is said almost two-thirds of our brain’s processing power is dedicated to vision and vision-related functions. It’s what kept our ancestors alive in the Stone Age and it’s what keeps us safe while driving or crossing a busy road. The eyes capture more information than any other sensory organ, which means that much of the brain’s working capabilities are spent in processing and making sense of what the eyes see, allowing us to react, make decisions and use our motor skills.

It is no wonder then, that for a long time now, we have tried to replicate the power of vision in various forms: from the time that pre-historic human beings drew on the walls of caves in a bid to store an image outside of the human mind to the camera that slowly yet steadily gave this power to the masses in ever-simplified ways and form factors.
