Refers to da humorously-annoying conundrum dat's
frequently encountered by folks suffering from C.S.S. (i.e., Can't See S**t"),
particularly those who also have poor short-term memory --- they set their glasses down someplace, but then they forget where they laid them, and they cannot see well enough without said
corrective lenses to find them again.
Keeping a spare pair of glasses (like simple reading-specs from da dollar store) in a certain place at all times (and then promptly returning them to said location after using them in a "mislaid glasses dilemma"
emergency, like a hidden set of house/car keys that you use whenever you've
accidentally "locked yourself out") can get you out of the age-old "I need my glasses in order to see well enough to FIND my glasses!" problem... you will always know where
in the house that your "rescue" glasses will be, so you can go and temporarily don them for clear vision till you find your "regular" glasses again, and then put the spare set back in their "for emergencies" location.
