Swim goggles could protect eyes in space travel

Astronauts returning from lengthy trips to space face eye and vision problems for years, so researchers have been trying to come up with ways to protect the eyes. One possible tool, according to a new study: swimming goggles. In a small study conducted at NASA Johnson Space Center in Houston, researchers found that participants who wore goggles as they exercised in a way that simulated being in space had higher intraocular pressure than those who didn’t wear goggles — an indication that their eyes were being safeguarded somewhat. The researchers noted it was a small study and needed additional investigation.
