The behaviour of the tear film exposed to the atmosphre for a relatively long time was observed by means of a Nomarski kmicroscope and the Zeiss slit‐lamp microscope SL 75. It was observed that the lipid layer of the tear film on the naked eye as well as over the contact lens consists of two structures: the homogeneous structure and a structure exhibiting a micell‐like one. The phenomenon is explained in terms of the specific properties of the different lipids in the gland secretions.
