"Need to see a thousand meters in the dark? Want one eye that's perfect for reading and another for long distances? Some eye surgeons are already at work reshaping corneas not only to fix patients' vision, but fit their careers. ... What do we have to thank for this custom technology? The space program. Wavefront technology, which was developed by NASA to improve the focus of the Hubble Space Telescope, has translated neatly to the human eye. The technology allows physicians to map the cornea and iris, enabling surgeons to make small, specific tweaks to the eye that result in custom eyesight made to order."
