Citation needed on this: but from what I understand, the way your brain processes vision is that some of what you "see" is in fact the past. The visual cortex keeps recently seen things around and the incoming visual information is mixed with the past images to create the present (almost like compression in a video). Thus it would make sense that after staring at the green lines for awhile your brain is using past information when looking at new lines and hence the illusion.
- georgemcbay 12y agoThis (what you described) is basically how most optical illusions of the type of "look at this thing then look at this other thing" work, but this one is a lot stranger than most in that the effects of it can reportedly last for up to 3 months. I can't vouch for that directly, but I'm still seeing it an hour later and some other responses here have mentioned that they actually are still seeing it months later. Other optical illusions that rely solely on the mechanism you're talking about fade in under a minute.
