Even the late 13th century when the first wearable spectacles were invented is later than I am interested Different strokes and all that.I don’t know what that is, but yeah Isaac Newton invented a lot of stuff and advanced other stuff, Paracelsus invented toxicology, alchemists invented optics, several tools still used in modern chemistry, and a bunch of other stuff.
