Eventually I found somewhere that did stock it ... ASDA of all people. Sainsburys, Tescos, various local pharmacies, and an opticians had failed me first. What a waste of a lunch time.
For those that don't already know I have an eye condition (keratoconus) for which I have to wear hard contact lenses; glasses just won't cut the mustard for me 'cos the problem is a lump on the surface of the eye. Without my lenses in I'm quite blind :) If you were a few feet away I'd only recognise you by voice or general body shape as all the features people usually use for identification would just be a big blur to me. This means that I get a bit paranoid about my eyes and lenses sometimes plus the condition can make the eyes more sensitive to light anyway.
Still I did get the solutions I needed so I can be a happy seeing bunny tonight :)
