If you put the word into an ebay search you'll come up with lots of eye wipes, lotions and sterile pads from reputable suppliers, if you can't get such things on prescription.
The real annoyance for me with it is that leaving my contact lenses out helps, particularly with the associated "dry eye", but then I can't see the computer properly. Now I wear my lenses until about 17.00 (when I stop for the day and switch the TV on) then take them out and use glasses for the evening.
It is incurable, as BaliRob said, but most of the time it's no trouble. As soon as I see the first sign of the crusty bits I go back to the eye wipes etc which calms it down again. It's really eye hygiene, I suppose.
