“Your eyes can deceive you, don’t trust them. Stretch out with your feelings.” Wise words from a wise Jedi. Obi-Wan Kenobi helped teach Luke Skywalker how not to cut his own arm off while wielding a lightsaber, and Nike’s SPARQ Vapor Strobe glasses are meant largely for the same purpose: to teach athletes the value of non-visual sensory perception.

These glasses feature LCD lenses that can be made to block out your vision for training purposes, helping to improve things like speed and reaction time as you’re forced to adapt to figuring out what’s going to happen next using senses other than sight.

Lightsabers might be the stuff of science fiction, but non-sight-based sensory training is very much real, and the $300 rechargeable SPARQ Vapor Strobe eyewear from Nike are designed for exactly that purpose.
