This episode I describe 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”. I also describe how we can train and support our visual system to improve at any age. I describe 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). I also explain how to use eyesight to improve our levels of alertness and why visual hallucinations, lazy eyes and colorblindness occur. I also describe 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.
