Space is a harsh environment, especially for human eyes. Intense cosmic radiation and prolonged exposure to artificial lighting aboard spacecraft can harm astronauts’ retinas. That’s where a unique ISS experiment comes into play—studying pigments from algae to shield vision in orbit.
The experiment, led by Dr. Maria Giardi from the Institute of Crystallography in Rome, explores the protective potential of macular pigments and eyespots extracted from algal organisms. These natural compounds are known for filtering harmful blue and ultraviolet light, which is also a concern in space.
Macular pigments are found in the human retina and help protect vision by acting like internal sunglasses. By studying similar pigments from algae—organisms that have evolved under extreme lighting conditions on Earth—scientists aim to develop biomaterials that can help astronauts retain healthy eyesight during long missions.
In the ISS experiment, these pigments are immobilized in an organic matrix to test their stability and protective efficiency in microgravity. The matrix simulates how these pigments might be used in wearable tech, eye drops, or dietary supplements for space travelers.
This research is especially critical for missions to the Moon, Mars, and beyond, where astronauts will face months or years of space radiation. A non-invasive method to safeguard vision would be a huge step forward in crew health and mission success.
It’s also a brilliant example of biotechnology in space—combining biology, chemistry, and materials science to tackle human challenges in extreme environments.
