Space Agencies Are Trying to Keep Astronauts From Losing Their Sight
Space agencies are partnering with tech startups to develop miniaturized eye-scanning technology to combat Spaceflight-associated neuro-ocular syndrome (SANS). This condition, which affects many astronauts, causes vision impairment due to fluid shifts in low-gravity environments.
Why it matters
Addressing long-term health risks is critical for the success of future deep-space missions and the safety of astronauts.
The agency has commissioned British eye-scanning startup Siloton to develop a solution ahead of the international Artemis flights to the moon and other deep space missions. The health tech uses quantum technology to shrink core components used in eye-testing equipment found at optometrists to fit on a photonic chip smaller than a coin.
Founded by physicists in 2020, Siloton is currently working with the UK’s National Health Service to enable patients with retinal conditions to self-scan at home. “The ESA pretty much has the same requirements,” says cofounder and chief technology officer Euan Allen. “It's just in a totally different environment.”
