Who came up with eyeglasses, and how?

Someone, somewhere, had the best idea. Not fancy shoes. Not a faster horse. Something nobody had ever thought to make: a way to see better. Before eyeglasses, if your eyes got blurry as you got older, you just… squinted a lot. You held books at arm's length. You gave up on tiny detailed work. And then, around the year 1285, in northern Italy, someone changed everything.
We don't know his name — no one signed the invention — but we know the place: probably a glassmaking workshop near Venice or Pisa. Glassmakers had been grinding and polishing chunks of clear glass into curved shapes for years, making decorative stones and magnifying crystals. One day, someone held two of these curved pieces of glass up to their eyes at the same time. And the world snapped into focus.
