Late sight is learned, not instant

When people regain vision after long blindness they do not immediately 'see' the world the way someone born sighted does; instead the brain must relearn how to map visual input onto objects, depth, motion and meaning through extended practice and multisensory calibration. This reframes sight restoration as a long learning process—not just a medical fix—and calls for rehabilitation programs that teach visual interpretation, not only ocular surgery or implants. — This changes expectations for vision‑restoring treatments, shifts funding and policy toward prolonged rehabilitation, and informs ethical and legal standards for new sight technologies.
