This is similar to what happens naturally when lipids are secreted from the meibomian glands (see figure 3) on to the lid margins where they form a reservoir. Blinking puts pressure on the meibomian glands, resulting in a small amount of oil being expressed onto the lid margins, and the lipids that were part of the tear film mix once again with the lipid reservoir on the lid margin. During the opening of the lids, some of the lipids from this reservoir spread onto the tear film, forming a lipid layer [1]Three main layers make up the normal tear film. In 80% of people with dry eye, the cause is deficiency or instability of the lipid layer Despite this, a 2016 survey of pharmacists*, showed that two out of three respondents were unaware that there are different types of dry eye condition, which have different aetiology, and therefore required different management.
