Observation of two structures of the tear film lipid layer.
The behaviour of the tear film exposed to the atmosphere for a relatively long time was observed by means of a Nomarski microscope 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 micelle-like one. The phenomenon is explained in terms of the specific properties of the different lipids in the gland secretions.
