For use with the jumbo JUMBO crossword puzzles. I'm glad procedures exist such as Lasik, to improve eyesight. My eyes, should fortune find me fair, will never get bad enough to warrant use of such a lens. If not used for reading, it seems possible to kill an entire ant hill at once with this large lens.
