It’s any interaction that counts. That could be with your eye, but it’s usually with any other particle that needs to know the position of another. That could be part of a measuring device, or anything else. If information is needed to “do physics” with it then the waveform collapses so the interaction can be performed.
It has absolutely nothing to do with consciousness.
