Nope, it's to keep your straps down and quieter. Plus most sunglasses are polycarbonate and aren't going to shatter like glass anyway

And, more seriously, where's the coverage of the closure of the cycle lane which forces you to cycle on the Totton bypass.

Adjusted rear mech following video, shifting very nice now and chain rub no more, thanks all
After giving the cassette a good thorough clean, all seems well again. I had a lot of gunk in between the cogs. Although I'll probably give the rear mech a bit of adjustment tomorrow as well.

rear D adjustment / setting by park tool
I concur.
Free the chain carefully so you don't cause more damage to the frame and then you may want to adjust your derailleur H stop screw to prevent it happening again: https://www.parktool.com/blog/repair-help/rear-derailleur-adjustment
It looks like your chain has got jammed between the smallest sprocket on the back wheel, and the frame itself.
