They say that love is blind.  
Well, I think that just the opposite is true.  Love lets you see people in their most perfect condition.  You see beyond the flaws.  You see them as better than they see themselves.  It’s like sleeping with your contacts in.  The night before, maybe you’re too lazy or tired to take them out, then you wake up the next morning and they’re sticky and cloudy and maybe there are some eye boogers floating around.  Just generally uncomfortable.  Then you take them out and clean them and you can see clearly again.  But then, every once in a while it will happen again, and it’s nobody’s fault but your own.  You could have taken them out, let your eyes rest for the night.  But no, you were too excited about snuggling up in bed to be bothered with saline solution.  After carrying on with this kind of behavior for too long, your eyes will probably get infected, swollen, red.  You’ll need to go to the doctor, but oh no your insurance doesn’t cover Vision, so now what?  You get some generic drops from the drug store and hope that you can self-medicate the problem away?  Not gonna happen.  Without proper treatment you could risk significant permanent damage.  You should probably keep a spare pair of lenses around, just to be on the safe side.
