Optokinetic reflex

We have others we have to start super slow.

And then we have some, even when we're doing, for example, optokinetic testing.

Optokinetic is when you've got a full-filled visual stimuli moving and moving.

We're looking to see how your eyes respond to that because that movement is how you stay stable in a moving environment.

This is where a lot of people get motion sickness, driving, being in grocery stores and everything else, and they think it's the physical activity, but it's often the visual processing.
