I read somewhere that when Teddy Roosevelt was attacking San Juan Hill, he was so paranoid about breaking his glasses that he had six or eight spare pairs with him. Now I'm not sure if this is fact or just legend, but it does bring up an interesting point: If you wear corrective lenses daily, what would you do in a PAW/SHTF/TEOTAWKI situation? Short of that, do you keep spares in you BOB?
I wear disposable contacts 95% of the time. For the most part I forget I even have them in, and I wear them for a couple months at a time, not even removing them to sleep. But there's been a time or two when Mr. Murphy struck my contacts at very inoportune moments, including once when I ripped on while I was driving. My eyes are pretty bad, nearly 6 cylinder power. Without contacts or glasses I'd be really screwed. There's no way I could hit anything smaller than a 5 gallon bucket with open sights at much over 30 yards, and I definitely can't drive. I can't even read a book at arms length.
At the moment I always keep a few extra pairs of contacts and one pair of glasses, but in a SHTF situation it would be a good idea to have at least 2, maybe even 3 pairs of glasses. And ideally they'd be something durable and protective, maybe something like
these. They're bulletproof and would be great safety glasses, plus they seem like they're really rugged.
If you're the type of person to keep several years worth of food and really think the wheels are gonna come off eventually, it would be smart to have as many pairs as you can afford. You prescription will change over the years as your eyes change, but even an outdated pair that wasn't perfect would be a helluva lot better than nothing. Of course, you could also buy a few pairs that were a couple steps beyond your present ones, too.
How do you guys and gals handle prescription lenses in an emergency situation?
