    Glasses. The ability to see so much better than I otherwise could leaves me astonished every time I put them on.

      Lenses also gave us telescopes and microscopes. Pretty amazing discovery.

      I wouldn’t have survived childhood without glasses in a pre-modern era.

        Same. I would be a ditch digger or something if I had survived.
