Agnirva Space Premier League - Expedition #30748: Eye Tracking in Space: How Microgravity Affects Vision and Coordination

In space, even simple tasks become complex due to the absence of gravity. One key area of concern is how astronauts visually track objects and maintain coordination. The Eye Tracking Device experiment, led by Dr. Andrew Clarke of Charite Medical School in Berlin, explored exactly this.

Conducted over multiple ISS expeditions, this study used a specially designed eye tracker developed by Kayser Threde in Munich. The device measured how astronauts’ eyes moved while performing different tasks in microgravity. By analyzing these patterns, researchers gained insight into how visual-motor coordination is altered in space.

Microgravity affects fluid distribution in the body, which can cause pressure changes in the eyes and potentially impair vision. Understanding these changes is vital for astronaut health and mission safety, particularly for extended missions to the Moon or Mars.

Beyond its applications in space, the research has relevance on Earth too. Eye tracking is a powerful diagnostic tool in neurology and psychology. The data from this experiment could improve therapies for conditions like vertigo, balance disorders, and even learning disabilities.

By studying how vision adapts to space, we not only safeguard astronauts but also enhance our understanding of the human brain.
