The development of Dynamic Contact Angle (DCA) and sessile drop method to measure the relative surface properties of contact lenses that occurs as a result of tear break up was discussed. Moreover, the use of Dynamic Vapor sorption was also discussed to study the dynamics of water loss and regain as the humidity changes during the blink cycle. It was found that the surface properties can influence both the interaction of the lens with proteinaceous and lipoidal tear components and the comfort of the lens. It was also found that the lens tends to lose water as a result of repeated tear break up.
