Several adapted rigid contact lens wearers were given duplicates of their present lenses made in different plastics. They were required to wear each material on each eye for a period of four hours. Both the average wetting angle and its range of values for each material was compiled. All lenses tended to give similar average wetting angles but ranges of angles for the PMMA/siloxanyl materials were greater than that for PMMA and GP IITM. Both values should be utilized when evaluating the wettability of a specific material.
