After suffering years of very severe dry eyes I have been told by my opticians I have a type of allergic conjunctivitis or GPC, I have been unable to tolerate my lenses for the past few months, I can manage an hour max and then I need to take them out as they are uncomfortable. They suggested two drops which I have started and have ordered new contact lenses to try, I won't see them for 2 weeks to ask but I was also wondering if my constant use of eye drops (Hycosan extra) or my solution could be an issue, has anyone any experience or advice?
