Welcome to Huberman Lab Essentials,
where we revisit past episodes for the most potent and actionable science-based tools for mental health,
physical health, and performance.
I'm Andrew Huberman,
and I'm a professor of neurobiology and ophthalmology at Stanford School of Medicine.
This podcast is separate from my teaching and research roles at Stanford.
It is however,
part of my desire and effort to bring zero cost to consumer information about science and science related tools to the general public.
Today's episode is going to be all about vision and eyesight,
a topic that's very near and dear to my heart
because it's the one that I've been focusing on for well over 25 years of my career.
When we hear the word vision, we most often think about eyesight.
or our ability to perceive shapes and objects and faces and colors.
However, our eyes are responsible for much more than that, including our mood,
our level of alertness, and all of that is included in what we call vision.
What is vision?
Well, vision starts with the eyes.
We have no what's called extraocular light perception.
While it feels good to have light on our skin,
while it feels good to be outside in the sunlight for most people,
