I purchased Clear Eyes Contact Lens relief because my contacts seem to dry up while Im driving. I had a few options, but this was the only product that had "soothing" on it. My eyes are sore and dry, and I wanted something that was going to help both! As soon as I put the Clear Eyes in, I noticed a difference. It was like I had a brand new pair of contacts in, thats how well it worked! The best part was a few hours later, my eyes were still great! I had figured I would need to add drops again, but I didnt! I went the whole day with eyes that felt good and I oculd see out of my contacts! It only took 1-2 drops, thats whats great. You wont have to use half the bottle in just a few applications, the bottle will last a long time! The price was good too, at 3.99 a bottle, it was the lowest price of the eye drops I looked at. Im always looking for a bargain or sale, and this was not on sale, but the price was perfect! I would definetly buy Clear Eyes again, it really did its job!
