I had a pair of glasses made up by Specsavers and they were next to useless... they had forgotten to install the prisms into the lens .... I went back to my optician and she sorted my glasses for me, I'll always use a proper optomerist/optician, my eyes are precious....
on the offchance, does anyone know if it's possible to get polarised reactolite lenses yet... swapping glasses is a pain and I always lose the clip ons
