Has anyone done this and if so what website would you recommend?
My partner is pretty blind and does a lot of running (15-20km a day) and we are looking to get a cheap pair of prescription sunglasses that would be suitable to use for this. She has managed to lose the old pair she was using and doesn't want to use her nice expensive pair for sport. We got a copy of her latest prescription from Specsavers so wondering which sites are reliable as there seem to be a lot of options.
