The eye’s normal tear film
The normal tear film has three layers:
Oily layer (outermost layer)- contains a complex mix of lipids from the Meibomian Glands in the eyelids.
Watery layer (middle layer)- contains fluid from the lacrimal gland. This is the thickest layer.
Mucous layer (inner layer)- contains mucous from the conjunctival goblet cells. This layer helps to anchor the tears to the cornea.
Over 86% of people with dry eyes show signs of Meibomian Gland Dysfunction [7]

How to treat dry eyes
One of the most important steps to treating dry eyes is to educate the person about dry eyes. This is best done at an eye examination. Patients often talk with their Optometrist or Ophthalmologist about some of the reasons they have dry eyes, the treatment options and the long term prognosis.
Dry eyes initially is treated by looking at a person’s lifestyle and work routines. This might mean reducing airflow, increasing humidity or tweaking the home or workplace.
Other changes such as identifying medication contributors and increasing supplements (e.g. omega-three) can help.
Eye drops and eyelid cleansers can also improve the comfort of dry eyes. Prescription eye drops can help.
These are some of the initial steps that can improve dry eyes. Read more about further dry eye treatments here.
Dry eye is chronic and progressive
Dry eyes is a condition that can be controlled but does not go away. Left untreated, it can lead to permanent damage to the eyes.
Screen time is here to stay. The prevalence of dry eye disease is likely to continue to rise.
