There have been many studies made as to the importance of the use of wetting solutions in the wearing of contact lenses. It is generally concluded that proper wettability of lenses is a significantly important factor in the improvement of wearing comfort. Wettability basically refers to a physio-chemical mechanism by means of which tears spread evenly over the lenses to form a coherent film. The compositions of the individual wetting solutions contribute in varying degrees to the wettability and wearing comfort. It is the purpose of this study to subjectively evaluate the variability in degrees of comfort and desirability of a number of wetting solutions currently available.
