I'm keep seeing this sort of glowing effect every time I am in a bright area then I shift my vision to the other side i can se e spot shimmering/glowing for seconds then it disappears, also when I close my eyes i an see this glowing effect. It is not permanent though, it is like a reaction from something ( I think light reaction? ) for years I see this, I wonder if it is normal, but sometimes this make me feel worried about my vision. I dislike seeing t hse things, although it does not interfere my vision.
