I have very dry eyes and therefore also struggling with long wear contact lenses. Now I've tried the products combined solution Hyaluron, Feuchtigeitstropfen and enzyme cleaner from Eyelike and can only say great product and great value. Have they now once cleaned and rinsed with the solution combined solution Hyaluron and see no burn or something. Great cleaning power where I wondered. Hope it stays that way for monthly lenses must still be cleaned three times !!! I am very satisfied and will continue to stay with the product, thank Eyelike.
