Astronaut Shubhanshu Shukla Demonstrates Eye Care in Space

In a recent demonstration, astronaut Shubhanshu Shukla showcased how astronauts can manage eye care in the unique environment of space. This presentation highlights the challenges of performing simple tasks like splashing water in one’s eyes while aboard the International Space Station (ISS).

A Unique Challenge in Microgravity

During his mission to the ISS in June 2025, Shukla learned that even basic routines require innovative solutions in microgravity. He explained that water in space does not behave as it does on Earth; instead of flowing or staying in place, it forms floating blobs that can make cleaning an injured eye quite difficult. “If anything happens in space, the nearest hospital is 400 km away,” Shukla noted. This distance underscores the critical importance of training astronauts in basic medical procedures.

To resolve the issue of eye care in microgravity, engineers have developed “sealed eye-irrigation goggles.” These specially designed goggles fit over the eyes and connect to two tubes: one that delivers sterile saline to wash the eye and another that uses suction to remove the liquid. Shukla emphasized that while this technology is a remarkable advancement for space medicine, it was not utilized during his mission.

Innovations for Astronauts

Shukla’s demonstration is part of a broader effort to educate the public about the complexities of life in space. He has shared various videos on social media, including a light-hearted tutorial on how astronauts maintain hygiene in microgravity, which he humorously dubbed the “world’s most expensive sponge bath.”

As the second Indian to visit the ISS, following Rakesh Sharma, Shukla’s experiences contribute to our understanding of space travel and the medical challenges astronauts face. His journey was part of the Axiom Mission 4, aimed at expanding human presence in low Earth orbit.

The insights provided by Shukla not only serve to entertain but also educate the public about the realities of space exploration and the innovative solutions developed to address everyday challenges encountered by astronauts.
