<p>The long-standing effort to achieve artificial sight can be classified into two complementary approaches. The first is the development of bioinspired optics and optoelectronics for machine vision, which takes cues from the different ocular structures and intricate retinal functions found across various species, and aims to enhance the visual capabilities of machines. The second approach focuses on biointegrated vision, which seeks to integrate intraocular prosthetics within the biological vision system to restore or enhance the sight of the visually impaired. As these two approaches evolve, their convergence is becoming more apparent, underlining the growing need for shared knowledge and collaboration. In this Review, we discuss bioinspired and biointegrated vision placing emphasis on visual devices that mimic the structures of the natural eyes and the information-processing capabilities of biological visual systems. Furthermore, we highlight opportunities for reciprocal exchange and collaborative development across these two disciplines.</p>
