I have a set similar to those but they were (years ago) about £8 from ebay.

(Good find). ;-)

Do you wear glasses and if so, do you find the two work together ok?

www.ebay.co.uk/itm/353264396577 (£8.29) is similar but worn like spectacles
or elastic headband.

Five 5 interchangeable lenses: 1.0x 1.5x 2.0x 2.5x 3.5x

I would prefer the solution that is addition to my 'background'
glasses (but thanks).
