Contact Lens Care Products Effect on Corneal Sensitivity and Patient Comfort.
Articles Eye & Contact Lens: Science & Clinical Practice. 32(3):128-132, May 2006.Epstein, Arthur B. O.D., F.A.A.O.

According to this study Optifree Express is more comfortable to patients than Renu Multiplus. Interestingly the study showed that Renu Multiplus decreases corneal sensitivity. One would think this is a good thing, but we must remember that corneal sensitivity is important to know when to blink. Decreased corneal sensitivity means decreased blinking, means increased dry eye. Consistent with that line of thinking is the fact that Renu Multiplus showed increased corneal staining.
