Spaceflight isn't easy on our bodies, and the eyes are no exception. A large proportion of astronauts experience vision problems , but researchers have now developed a new AI-powered detection tool to predict these issues before liftoff.

The US team focused specifically on spaceflight associated neuro-ocular syndrome (SANS), the term for vision degradation linked to time in space.

While symptoms of SANS can improve after astronauts return to Earth , that's not always the case. Being able to identify who's at risk could allow for preventative steps before missions even begin.

"Our models showed promising accuracy, even when trained on limited data," says ophthalmologist Alex Huang, from the University of California, San Diego (UC San Diego).

"We're essentially using AI to give
