What is the Saccade Test? 

I had this “balance test” post a workplace blast that left me with visual/physical/psychological damages accompanied by tinnitus/headaches/sleep apnea/vertigo and anxiety attacks. I was wrecked ALL Day feeling nauseous and sick

They REALLY should warn people prior to the test. I drove home and had to pull over (off the highway) twice! I felt as if I were Driving intoxicated
