Low strength cheap reading glasses

[AtlasAscendant]

Does anyone know where sells reading glasses in powers less than +1 ?

I've just spent ££££ on new glasses but just looking for something cheap for when I'm wearing my contacts. I'm coeliac so have to spend more time studying ingredient lists than I'd like.

Primark do. Around £1.50.

I get mine from Tiger Specs. They are very reasonably priced, good quality and do a range of strengths (starting at +0.5). They also do special offers, so I tend to get a couple of pairs at a time.
