Previous studies of optical interference from the whole thickness of the precorneal tear film showed much lower contrast than from the pre-contact lens tear film. It is hypothesized that the recorded low contrast is related to roughness of the corneal surface compared with the smooth contact lens surface. This hypothesis is tested, and characteristics of this roughness are studied.
