I suddenly started getting extremely dry eyes during the night. I spoke to a very knowledgeable gentleman at GoOpticians who gave me some sound advice. I didn't feel rushed and he listened to all I had to say about my problem. He then suggested some eye drops and a gel formula that he thought might help me. He told me about the trial packs for both solutions, which have proven to be very effective. The ordering process was very simple and the products only took 2 days to arrive. I only had to pay for the postage via PayPal. Overall a very satisfactory service, and I would highy recommend them.
