In this Huberman Lab Essentials episode, I discuss the science of vision and share simple, effective tools to enhance eyesight and preserve eye health.I explain how the eyes and brain work together to process light, color and motion using specialized structures such as the retina and photoreceptors, and why conditions like nearsightedness, visual hallucinations and lazy eye occur. I also cover specific visual protocols to increase alertness and focus during work, improve sleep, and support visual health. Additionally, I highlight key vitamins essential for vision and discuss supplements such as lutein and astaxanthin for maintaining long-term eye health.Huberman Lab Essentials are short episodes—approximately 30 minutes—focused on essential science and protocol takeaways from past Huberman Lab episodes.
