#427: The Hidden Link Between Vision, Longevity & Anxiety | Spatial Empathy, Screens & the 20-20-20 Rule With Dr. Meenal Agarwal
4/7/20261 hr 28 min
Today, I'm joined by the insightful Dr. Meenal Agarwal, an eye doctor and passionate advocate for reimagining how we think about vision and brain health. In our conversation, Dr. Agarwal reveals the surprising ways our daily screen habits are shaping not just our eyesight, but also our emotional regulation, cognitive performance, and even the development of anxiety and ADHD-like symptoms. She opens up about her own journey—from an unexpected period of cognitive "off-ness" during a stint away from her clinical work, to pioneering a powerful perspective on "spatial awareness processing disorder."
