As it happens, I've just got myself a pair of prescription sunglasses. Maybe not the last word in fashion, but win hands down on cost. They cost me - £0.00

. How come? Well it's all to do with the optician's 2-for-1 offer: I actually needed three new (non-tint) pairs: bifocals, single-focus distance (for astro etc.), and middle-distance for computer. They said they couldn't do 3-for-1, but they could do 4-for-2, so what would I like for the fourth pair? I said I don't know. They said, what about tints? I said OK, I'll try the tints. So now I have them!

Not sure how much I'll use them, but blocking more of the UVA from my eyes can only be a Good Thing...
