Honestly I mixed up different phenomena for “visual snow” in my description:
1. Visual Snow—Like a million very tiny dots. Very much like static/white noise
2. Patterned lines (?) - Like the geometric shape in this picture. Doesn’t have to be that consistent or patterned but is better described by “lines” than either of the other two.
3. Blue-sky Sprites—The picture is a nice animation. This can be seen without looking at the blue sky but apparently it’s more prominent in that case.
Yes, I meant #1. It’s only noticeable with my eyes open when I look at a textureless dark surface. If I sit with my eyes closed and concentrate on the visual snow for several minutes, it will usually progress to level 2 or 3 described here. But that goes away immediately when I open my eyes, unless the surroundings are completely dark.
