Neuralink, the brain-chip startup founded by Elon Musk, has made a significant stride in its mission to restore vision for individuals who have lost their sight. On September 17, 2024, the U.S. Food and Drug Administration (FDA) granted the company’s experimental visual implant, named Blindsight, the highly sought-after “breakthrough device” designation.
This classification marks a critical milestone in Neuralink’s journey to develop advanced neurotechnology aimed at addressing some of the most challenging medical conditions.
Blindsight is a groundbreaking device designed to enable visual perception in individuals who have been rendered completely blind, including those without functioning eyes or an optic nerve.
Neuralink’s founder, Elon Musk, stated that the implant holds the potential to allow users to “see” by processing neural signals, even if they have lost both eyes. This revolutionary step forward, particularly for patients who have been blind since birth, offers hope for a new approach to restoring vision through direct brain interfacing.
The Blindsight device from Neuralink will enable even those who have lost both eyes and their optic nerve to see.
Provided the visual cortex is intact, it will even enable those who have been blind from birth to see for the first time.

The FDA’s breakthrough designation is reserved for medical devices that provide treatment or diagnosis for life-threatening or irreversibly debilitating conditions. The goal is to accelerate the development and regulatory review of innovative technologies that hold promise for patients with few or no current treatment options.
Neuralink’s Blindsight implant falls squarely into this category, offering potential life-changing benefits for those who have lost their sight.
The Science Behind Blindsight
Neuralink’s Blindsight device leverages cutting-edge neurotechnology to process and transmit neural signals directly from the brain. Unlike traditional treatments for blindness that rely on the health of the eyes and optic nerve, Blindsight bypasses these entirely.
By stimulating the visual cortex—the part of the brain responsible for processing visual information—the implant could allow users to perceive visual inputs in a way that mimics natural sight.
According to Musk, the device could restore vision even to individuals whose eyes or optic nerves have been damaged beyond repair. While initial visual resolution is expected to be relatively basic, similar to the graphics of early video games, the potential for future improvements is vast.

The technology could eventually allow users to perceive more complex images, including objects in different wavelengths such as infrared and ultraviolet light.
One of the most remarkable aspects of Blindsight is its capacity to work even when the traditional pathways for sight, such as the eyes and optic nerves, are no longer functional. This approach sets Neuralink’s technology apart from other visual restoration devices that depend on the patient retaining some level of optical functionality. For people who have been blind since birth or lost their vision entirely, Blindsight offers an unprecedented possibility for regaining perception of the world around them.
The FDA’s Breakthrough Designation
The FDA’s breakthrough device designation is a testament to the potential of Blindsight to transform lives. This designation is not easily granted, and it highlights the device’s ability to address a critical unmet medical need.
The breakthrough status allows for more frequent interaction with the FDA, streamlined approval processes, and priority review. It could also help speed up the path to human trials, something Neuralink has been keen to achieve since its inception in 2016.
As of now, Neuralink has not disclosed when it plans to begin human trials for Blindsight. However, the company’s progress has been significant. Earlier in 2023, Neuralink received approval for its first human study involving its brain-chip technology, marking the beginning of the company’s direct engagement with the regulatory process. These trials are crucial steps towards making Blindsight widely available to patients in need.
Additional Neuralink Projects
While Blindsight is one of Neuralink’s most ambitious projects, it is not the only medical breakthrough the company is working on. Neuralink is also developing a brain-chip interface that could assist disabled individuals in performing everyday tasks such as moving, communicating, and interacting with digital devices. This implant could provide a new level of autonomy to people with spinal cord injuries or neurological conditions that impair their ability to move.

The company is currently testing an implant that enables paralysed patients to control devices like smartphones and computers using only their thoughts. This implant could help individuals regain independence by allowing them to perform digital tasks without the need for physical input.
Neuralink has been working with a small group of patients to evaluate the effectiveness of the device, with plans to expand its clinical trials in the near future.
Neuralink’s first human trial, which was approved by the FDA in May 2023, involves enrolling three patients who will test the brain-chip technology over the course of several years. These studies are vital for refining the safety and efficacy of the devices before they can be widely used.
Neuralink’s team of engineers, neuroscientists, and medical experts are working to ensure that these technologies are both practical and safe for patients to use in their daily lives.
