ADVICE

Sunlight Viewing

View sunlight, even through clouds, for 2-10 minutes during sunrise and sunset.
This improves sleep, mood, hormones, metabolism, pain threshold, learning, and memory.

ADVICE

Outdoor Time

Spend two hours outdoors daily without sunglasses to reduce myopia risk.
This applies to both children and adults and involves getting sunlight exposure.

ADVICE

Vision Breaks

For every 30 minutes of close-up work, relax your eyes and look into the distance.
Every 90 minutes, take a 20-30 minute break to view distant objects or go outside.

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.
