Elon Musk's Neuralink has achieved a significant milestone by receiving the FDA's 'Breakthrough Device' designation for its brain implant, Blindsight, aimed at restoring vision. This status is intended to expedite the development and review of medical devices addressing severe conditions. Blindsight could enable people who have lost their eyes or optic nerve to regain sight, and potentially allow those blind from birth to see, provided their visual cortex is intact. Initial vision quality will be low resolution but may eventually surpass natural vision, including capabilities to see in infrared, ultraviolet, or radar wavelengths. Neuralink is also working on another implant to help paralyzed patients control digital devices using their thoughts. The company has not yet announced when human trials for Blindsight will begin.
