Vision Problems

Pp. 217-227 (11)

Dirk C. Gibson


Vision problems and eye damage in space were the topic of this chapter. The fact that microgravity causes vision loss was documented, with a trio of specific eye maladies discussed. A half-dozen possible causes of space-related vision loss were analyzed. The similarity of space vision issues to a pair of terrestrial maladies was recognized. The magnitude of the space vision degradation problem was quantified, and the question of whether or not this damage is permanent was addressed. It was documented that many spacefarer vision problems occur after astronauts return to Earth. A one-month threshold for space-induced eye issues was documented. NASA interest in this issue was discussed as were NASA policy acts regarding vision degradation. Studies on vision changes in microgravity were considered.
