It's a link, not a cause and effect, but it's a link between coffee and longevity.

It's pretty compelling, and that is something you should know.

One of the greatest human inventions doesn't get nearly enough credit.

Eyeglasses.

Think about it.

Without them, millions of people wouldn't be able to read, drive, recognize faces, or even function comfortably in the world.

Glasses didn't just improve vision, they radically expanded who could learn, work, and participate fully in society.

And yet, for a long time, wearing glasses made you a target, especially as a kid.

Glasses meant you were nerdy and awkward, somehow deficient.

They were a medical device, something to fix what was wrong with you.

Well, then fast forward to today, and the script has completely flipped.

Glasses today are fashion.

People who don't even need them wear them.

Sunglasses are practically mandatory for everyone.

Frames signal intelligence, cool, seriousness, creativity.

We've gone from hiding glasses to showing them off.

So how did this happen?

How did a tool for correcting a flaw become a cultural symbol?

And what did eyeglasses change about how humans see the world?

That's what we're diving into today with David King Dunaway.
