Not a biologist but it’s called blue light entoptic phenomenon. Pretty interesting in general.

I know they are not parasites, but what are they? Strings of dead cells? Dead optical nerve? Any biologists here?

Wouldn’t these be floaters? en.wikipedia.org/wiki/Floater

Hmm it says they’re proteins… I wonder how many times magnification it has to be for it to appear the same size as a tree.
AnUnusualRelic@lemmy.world 9 months ago
It depends on the tree, obviously.

Or how close to your eye to give the perspective of the same size?

For anyone too lazy to look:
Some may be individual red blood cells swollen due to osmotic pressure. Others may be chains of red blood cells stuck together; diffraction patterns can be seen around these. Others may be “coagula of the proteins of the vitreous gel, to embryonic remnants, or the condensation round the walls of Cloquet’s canal” that exist in pockets of liquid within the vitreous.

Fascinating

I see that sometimes when I cough or sneeze too hard.

If it’s a persistent pattern, it’s likely to just be variation in the density of the vitreous humor (eye jelly).
