We are looking for subjects who find their contact lenses are not as comfortable as they would like, especially at the end of the day. The trial does not involve changing lenses or solutions but rather using a means to retain more tears on the eye surface. the object of the clinical trial is to determine if retaining more tears on the eye surface reduces contact lens discomfort.
