It's pretty amazing to think that strobe lights in a club, the ones that make you kind of dizzy, could actually help our brains process images.
Duke researchers knew that they were on to something. They had done at least one other study on "stroboscopic visual conditions." So, they teamed up with some men whose livelihoods depend on visual acuity, hockey players, to test their theories out.
They designed special glasses with kind of an internal strobe light. The glasses intermittently let vision in, and then cut it off.
