116: What Screen Time Is Really Doing to Your Eyes, Brain, and Stress Levels

One of the most overlooked aspects of health may be influencing how you think, learn, focus, perform, and even respond to stress every single day. In this episode, I sit down with neuro-optometrist Dr. Bryce Appelbaum to explore the difference between eyesight and vision, and why seeing 20/20 doesn't necessarily mean your visual system is functioning optimally. We discuss how the eyes and brain work together, the role vision plays in learning, reading, athletic performance, spatial awareness, and everyday confidence, and why many functional vision problems often go unrecognized. We also spend time talking about something that affects nearly all of us: screen time. Dr. Appelbaum explains what prolonged screen exposure is doing to our visual system, nervous system, sleep, stress response, and overall well-being.  Topics We Cover in This Episode:  How eyesight and vision are related, and why they're not the same thing The subtle signs that may point to an underlying functional vision problem Why screen fatigue may involve much more than tired eyes What vision has to do with focus, learning, reading, and information processing The connection between visual function, stress, and nervous system regulation Why some people struggle with motion sickness, bridges, tunnels, or spatial awareness How vision training differs from traditional eye care approaches Simple daily habits that may help support long-term visual health Whether you're a parent, athlete, professional, avid screen user, or simply interested in optimizing your health, this conversation offers a fascinating perspective on the connection between vision and whole-body wellness.
