Predicting Solution properties

Abstract

A tacit assumption, often made by patients and practitioners alike, is that the properties of contact lens solutions (e.g. relative acidity, buffering capacity, osmolarity, viscosity...) are dictated directly by the intended use(s) listed on a product's label. But for the assumption to be correct, another assumption might be made as well, that is, that there should be a single "best" combination of properties to accomplish the label stated mission. Another way of saying this is that solutions in a particular use class might be expected to hover within narrow limits, around a set of ideal (pH, buffer, viscosity..) values, and consequently would end up looking very similar to one another in their property profiles.
