Dizziness From Spinning

i don't think my personal experiment really settled the question. Andand it could be ther confounding varia variables. But i did find that it at least seemed possible to me that having your eyes open during spinning makes the dizziness issue significantly worse than than spinning with the eyes closed. Which would seem to lend some credence to the explanation offered by karadmond, that it has something to do with the the movement of the eyes. Maybe it's actually worse to be spinning for a longer period of time slower than a shorter period of time really fast.
