“I do think this is enough to recommend this vision test be used routinely,” Dr. Clugston commented. “This test is less subjective than some of the other tests used currently. An assessment of balance is always very subjective, and cognition tests can be too. But the vision test just involves reading numbers from a screen as fast you can. It is very simple and less easily manipulated by the athlete. But it is best used in combination with the standard tests.”
