the glow in the dark shouldn't bother their eyes at all.
There are vendors that sell glow in the dark toys with glow in the dark chain. Further more most nocturnal animals need some amount of light to see though it's usually soft moon light or night light...I can't imagine the glow from the wheel would be all that bright and will dim through the night as it loses it's charge.
My only concern with glowing products is toxicity from whatever chemicals are used to make it glow. But my boyfriend and I are a little anal about potential issues
Having said that I've never heard of any issues blamed on glowing products and even if your gliders are chewers they aren't likely to swallow it so I wouldn't worry about it, it's just a unlikely potential that is always the first thing I think of when I see glowing stuff lol.
