Hello, if you think you might have illusorry palinopsia, here is a quick test for you:

1. Look at your hand with a relatively bright backround (Not low contrast)

2. Move your hand really quick from that one side to another.

3. You should see your hand stay behind for a tiny fraction of a second, almost not noticeable. If it lingers for longer than that one fraction of a second, you might have palinopsia.

This fraction of a second afterimage is caused by your brain's "refresh rate". With illusorry palinopsia, this refresh rate is slowed, which causes you to see it for longer. For me this confirmed that I dont have palinopsia, maybe it will help you too! 😁

I have seen alot of vague stories about this subject, the best thing to know, is that lots of people are blurry trails behind moving objects, so do I. The blur, should be only in your peripheral vision. This means it should be eliminated when you follow the object with your eyes.

The difference between neurological and occular afterimages is that neurological afterimages usually takes many minutes to disappear while occular afterimages disappear within a minute.

I want to warn you against googling, as you will only get weird responses, when your afterimages only last a few seconds, they are normal and you should ignore them.

You should only worry if you see double trails of normal moving objects, (moving your phone in the dark is NOT a normal object, this can create multiple images due to the not continuous lightning).

I hope you're doing well!

I was wondering if the snow for you guys becomes a bit worse or more visible if you squint? For me it does but im not yet diagnosed so I cant say whether I have it or not.
