As I stood at the first station, my already blurry vision became significantly worse and then distorted around the edges. This quickly turned into tunnel vision and soon all I could see was whatever was directly in front of me. I was experiencing the effects of glaucoma, Ferren, the co-founder of Applied Minds and the mastermind behind the suit, told me. After that, floaters and flashes of light zoomed in front of my eyes, I saw fringes of color around the edges of the treadmill in front of me (cataracts) and gradually I lost my vision all together. “This is age-related macular degeneration,” Ferren explained. Ferren flipped a switch and I was relieved to have my normal blurry vision back.
