The European Space Agency is trying to understand why astronauts lose their eyesight in space, in the hope they can figure out how to treat—or even prevent—the condition as looming longer spaceflights heighten the risk of permanent vision damage.

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.”

Spaceflight-associated neuro-ocular syndrome (SANS) is a collection of eye and...
