How Screens Train Tunnel Vision

This episode is brought to you by Our Place, Bon Charge, Cozy Earth, and Maui Nui.

We tend to think of vision as an eye issue. But it’s really a brain issue. Nearly half the brain is involved in processing visual information, which means the way we use our eyes can shape our focus, energy, and cognitive performance more than most people realize.

Today on The Dhru Purohit Show, Dhru sits down with neuro-optometrist Dr. Bryce Appelbaum to explore why our vision is about far more than eyesight, and how the way we use our eyes every day can profoundly shape brain function, focus, and overall well-being. Dr. Appelbaum explains how modern habits, especially constant screen exposure, are quietly straining our visual system and nervous system. He shares practical strategies to reduce daily eye stress, exercises that can strengthen your visual system and improve attention, and the role of peripheral awareness, movement, and sports in training the eye-brain connection. Dr. Appelbaum also debunks common myths about dyslexia and reading challenges, discusses blue light and screen overload, and breaks down his approach to building visual resilience in a digital world. 

Dr. Bryce Appelbaum is a neuro-optometrist and the founder and CEO of MyVisionFirst, a leading practice specializing in functional vision care for all ages. He is known for his work optimizing the eye-brain connection through Vision Performance Training, helping patients recover from concussion-related vision issues, improve visual performance, and build resilience in today’s screen-heavy world.
