Hi, pelvicfloor'Glasses direct' have been really goodI used them first two years ago and then after DD broke those glasses I bought two pairs in march. One, standard pair of thin gold frames for about £15, (to replace my previous really quite funky black ones--always mistaken for being v. expensive) and some prescription sunglasses which came to £35 because of the tint.
They have sales and offers on quite often, and post to Ireland. They turned up from England after 5 days this time which was brilliant I thought.
To pick the glasses there is a catalogue, or you can scan in a small pick of yourself and try them on on their website. It can be a bit prone to bouncing you out of this process and there's no way to store a shortlist on the site, so if you're using it and you want to compare a few pairs, make a note of the styles on paper.
Hope this helps.
