1) I know. It just amuses me
2) Nobody really knows. Been to several different specialists over many years.
All we know is that my corneas keep breaking down. This has caused veins to steadily grow from the outskirts of my eyes towards my pupils, so when my heart beat goes up they swell distorting my vision. In addition to that, scars form as part of the healing process which distorts it further while also messing up the shape of the corneas which ALSO distorts it.
I basically have 30+ images overlapping each other in numerous ways, objects without a clear contrast to each other or the background will appear as merged, large parts of what I see is heavily blurred, and of course the overlaps cause colours to blend too.
(For some idea of what this actually looks like just google image search light distortion, but I can't find anything good or I'd post it)
