I know they are not parasites, but what are they? Strings of dead cells? Dead optical nerve? Any biologists here?
If it's a persistent pattern, it's likely to just be variation in the density of the vitreous humor (eye jelly).
Not a biologist but it's called blue light entoptic phenomenon. Pretty interesting in general.
Wouldn't these be floaters?
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.
It depends on the tree, obviously.
Or how close to your eye to give the perspective of the same size?
"These are small ... but the ones out there are far away."
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.
That's a different phenomenon from the picture. The picture shows a body in the vitreous jelly. The article you linked is a "brain filling in gaps" phenomenon.
Still, very cool article. I had never read about that.
Fascinating
I see that sometimes when I cough or sneeze too hard.
