Deepak Kumar on Instagram: "It's possible that some people can control pupil but it's rare. Studies show some individuals can voluntarily control pupil size directly, like a case dilating by 0.8mm and constricting by 2.4mm without indirect tricks (e.g., focusing or imagining light). Most people can't, as it's autonomic. The video seems to demonstrate this."
