I’ve heard that during eye procedures such as lasik doctors will ask patients to wiggle a specific toe or do some other specific small movement to relax your eye/help get it into the right position.
Why does a small unrelated movement affect the eye? What’s the neural pathway for how it works?
I’ve tried looking it up online and haven’t found a satisfying answer other than “it distracts your brain” which doesn’t explain much. It just seems like a really random way to affect the eye.
