UG, yes; despite being spritely enough to retain possession of 6/6 eyesight I read the recent missive about CFS, and they're offering lenses to certain groups of aircrew.
Group 1 were most front-end aircrew, who can have a couple of pairs of CFS, some sunglasses, and/or (can't remember which) opt for contact lenses at public expense. The idea was it's paid for by not offering CFS to non-flying aircrew and it's important because CFS don't work well with NVGs etc.
If you're in one of the other groups then you might not be offered them, but if you ever have to wear NVGs you're in.
