Good old Ben, without him we could never had had the wonderful invention of the bifocal when we did. I’m hoping to have my eyes zapped with that LASIK or photorefractive keratectomy thing that they do now days but I suspect that when I get older I’ll lose the ability to focus on close up objects. I’ve noticed it starting already, just means I’m getting old and that bites. Anyway, when I get my first pair of bifocals I’ll have Ben Franklin to thank for them. And my insurance company too, lets not forget them.
Bifocals, the combination of both concave and convex lenses for both types of vision correction, a top lens for distant viewing and a lower lens for reading, were developed around 1760 by the American statesman and inventor Benjamin Franklin.
