Every few years, I get new glasses, not because my prescription has changed (it's been pretty stable for about a decade), but because my old spectacles simply get old and worn out. This year, I took advantage of a two-for-one sale and got one set of new plastic frames (centre below) and one set of metal ones (right):
They're not a big change from my old set (left), but I like the new looks, though I'm not sure which of the two I prefer. Back in 2008 when I bought my last set, I wasn't sure I'd survive long enough to need new ones, but here I am. Yay.
Which pair do you prefer?
