Sometimes when we say “I can’t afford LASIK” or “I’m probably not a good candidate for LASIK,” what we really mean is “I’m afraid of LASIK.”
Not that those other points aren’t legitimate. Many people actually save a lot of money switching to LASIK from contacts, and there’s a lot of good information out there on whether or not you may be a candidate.
As for fear, that’s a perfectly reasonable emotional reaction to the thought of eye surgery.
LASIK is a medical procedure and so you want to give it all the same careful thought and consideration that you’d give any medical procedure.
