Tonight I (though I) was caught without contact solution in a situation where I couldn't toss my contacts and start over, so I spent some time on the internet learning about making my own distilled water, the various types of saline solution, what not to do, etc. Found this article, have broken nearly every rule on it, as I suspect have most of you contact lens wearers.
Then I remembered I had fucking solution (old no doubt but better than nothing) in my car.
