If you wear glasses or contacts and are a candidate for LASIK (or similar eye surgery)–and can afford it(!)–you should know that having it done, and being able to see, is mind blowing.  So worth it not to worry about (or have to deal with) losing or destroying a contact lens, or breaking or losing your glasses ever again.  Just think of all of the room you will save in your carry-on liquids quart-sized bag not having to bring contact lens solution when you travel! Mind.  Blowing.  (In a good way.)
