Ever stared at the bright sky and noticed tiny floating dots or squiggly strands drifting across your vision? In today’s episode, Gordy dives into one of the most common — and misunderstood — visual quirks: eye floaters.
They’ve been described since Leonardo da Vinci’s notebooks, feared as insects by early physicians, and are now understood through the science of posterior vitreous detachment — the process behind those mysterious shapes you sometimes see floating across your eyes.
In this episode of Smartest Year Ever, you’ll learn:
What causes eye floaters and how they form inside the vitreous humor.
Why they move when your eyes move (and why the effect is delayed).
How aging changes the structure of your eyes, and when to take floaters seriously.
The fascinating history of muscae volitantes, or “flying flies,” as they were once called.
Why your own brain quietly edits them out over time — like visual tinnitus.
This episode blends ophthalmology, history, and human biology into a fascinating look at how our eyes — and minds — perceive reality.
So next time you catch something drifting across your vision, you’ll know it’s not a ghost, not a bug — it’s you.
