The Science of Vision, Eye Health & Seeing Better

Listen: YouTube | Apple Podcasts | Spotify

In this episode, Dr. Huberman describes how we see, meaning how our eyes focus, convert light information into electricity the rest of the brain can understand and how our brain creates the incredible thing we experience as “sight.” He also describes how we can train and support our visual system to improve at any age. He describes more than a dozen protocols to support depth perception, offset near-sightedness, improve mood, sleep, and our ability to focus (both visual focus and our mental focus generally). He also explains how to use eyesight to improve our levels of alertness and why visual hallucinations, lazy eyes and colorblindness occur. Dr. Huberman also describes various compounds that may assist in supporting visual health and possibly improve our vision. Many simple, zero-cost protocols and a lot of scientific mechanisms are covered in this episode in clear language anyone can understand—it is for anyone that values their brain and whether eyesight, young, adult-age or advanced age.
