My normally reticent co-worker walks back into the office, presumably from smoking outside, and the lenses of her glasses are already changing from tinted to clear beneath the fluorescents.
"Oh, are those the Transitions glasses?" I ask, making conversation, since Katie has the same ones.
"Oh yeah," my co-worker says, "I just love them, but the last place I went they didn't get the prescription right."
"I got progressive lenses, and I still couldn't see - had to read with a magnifying glass even when I was wearing glasses," she continues, miming bending over a desk with an invisible hand held lens, squinting.
