I am wearing lenses for about 7 years now, tried many products and I have been constantly looking for a product that will make my lenses more bearable. I don't have major problem, but my eyes usually feels dry and itchy after wearing my lenses for more than 8hrs, changing temperature or humidity, and having a small nap in a train.
This product really helped. Might not make a huge difference if you never experienced any discomfort, but if you "feel" your lenses at least once a day, then this product might be for you.
