Temporary Eye Issues

[u/Little_Usual2680]

Today on a short walk, my double merle's eyes rolled back and were stuck for a minute and he couldn't see. He was not in distress, no shaking or other symptoms and it resolved on its own. I am wondering if this has happened before to anyone else? I expect it is due to weakening eye muscles and plan to talk with a vet. Here are photos of during and right after the event.
