Developing a visual prosthesis for the blind has been a long-standing goal. Despite decades of research, a truly useful electronic visual prosthesis remains elusive, with significant obstacles yet to overcome.

Area of Science:

  • Biomedical Engineering
  • Neuroscience
  • Ophthalmology

Background:

  • The development of visual prostheses aims to restore sight for individuals with blindness or partial sight.
  • Despite over 30 years of research, a functional electronic visual prosthesis has not yet been realized.

Purpose of the Study:

  • To review historical attempts at creating visual prostheses.
  • To assess the current state-of-the-art in visual prosthesis technology.
  • To identify key challenges hindering the development of effective electronic visual prostheses.

Main Methods:

  • Literature review of past and present visual prosthesis research.
  • Analysis of technological advancements and limitations.
  • Identification of scientific and engineering hurdles.
