Over at Jen Gagne’s blog, she mentions Visian implantable corrective lenses. These are little lenses which get implanted between your cornea and retina, to permanently correct vision problems. It’s reportedly much less invasive and has a much higher success rate than Lasik, and is not permanent! You can even have the lenses changed as your vision changes over the years.
I’m not ready for something like this yet, as I only need to use corrective lenses when flying, watching a movie, or trying to read a chalkboard, but if my vision gets worse as I age (probably will!), this will definitely be an attractive option!
