Eyes

During experiments, lots of observations are made by our eyes.

Most information we get is from our eyes' observations, if in fact that everyone would have different pictures in mind witnessing the same phenomenon, no one actually knows. We assume that everyone is seeing the same thing so same picture would be seen.

But what if actually not?

If there are limitations on eyes for us to obtain information then what else can we use to do observations accurately without our eyes?

Pictures, taken from multiple angles, in visible light or other wavelengths. Laser measurement of distances. Holography. (I think anyway. I've never heard of it being used, but I can't see why not.) Gate timers, etc. That would cover most of what might happen in a physical setup anyway. Obviously there is other equipment to pick up on other kinds of phenomena.
