Vintage 1970s or early 80s clip-on sunglasses, with simple plastic case from Boots. 

Classic "pilot" style sun specs with brown lenses.

A funky/wacky vintage look for a party or stag do/hen do, but also perfectly usable if you just want some clip-on sun protection!

They may be polaroid (my late father, who these belonged to, was obsessed with polaroid glasses) but I'm not sure how to tell. 

They may have been bought in Boots, but there's no way to tell if the case I found them in is original to them, or simply something my Dad popped them in for convenience.

Used condition, with visible wear and tear, and priced accordingly.
