Can you share more info (exposure time, etc.) about how that happened? How big was Saturn's shape through the reflector? I wouldnt have expected that to hap

  Degraded purely temporarily. Flashbulb effect in a dark room, lingering phosphene neon-blur overlay for 2-3 minutes. Not damaged forever, retinal burn. Sorry. bad language on my part. I do not believe you can damage eyes because of reflected sunlight off planets or moons, through a telescope. If somebody can find a fresnel lens fire-starter for moonlight, I'll learn to smoke midnight cigars to light them. But you definitely can suffer temporary light adaption loss, from the huge difference between what you see in the scope or binoculars, and what you see with full eyes, in the wide. It was 40 years ago, I wouldn't even know what kind of lens was on the eyescope. Saturn was maybe 1/5th of the visual field? Binoculars, 30x or 50x you're already looking at segments of the Moon, not the entire face I think.
