Bill Lundgren interviews Lily Turkstra, a PhD researcher at UC Santa Barbara, on the realities of visual prostheses. They unpack who qualifies, what “seeing” with phosphenes is like, how training works, and why expectation-setting and mental health support are critical. Takeaways: current implants provide rudimentary perception, not natural vision; outcomes vary; support systems and rehab matter; independence gains are possible but individualized; clinicians and families must align on expectations.
