As of 2015940 million people suffer from a form of visual impairment. Today, some forms of blindness can be cured by cornea implants and other procedures.

Despite advances in bioprinting and camera miniaturization, the issue of optical connection remains when attempting to replace the human eye. So far, technological progress has largely not risen to the challenge that 2.0 poises.
