Apollo 17 Continuous Light Flashes During Dark Adaptation

Astronaut Schmitt reported seeing light flashes continuously throughout the transearth phase when dark-adapted, with a notable absence during a period when the crew wore blindfolds for an experiment.
“We had light flashes just about continuously during the whole flight when we were dark adapted. I had one which I thought was a flash on the lunar surface. That one period of time when we had the blindfolds on for the ALFMED experiment there were just no visible flashes, although that evening, that night, before I went to sleep I noticed that I was seeing the light flashes again.”
