The tear film clinic covers all tear film abnormalities from dry eyes to watery eyes. We take referrals from local GPs in the areas of Northolt, Greenford, Ealing, Hillingdon, Harrow and further afield. Tear film abnormalities can cause a number of problems from dry eyes (keratoconjunctivitis sicca) to watery eyes (epiphora). The causes are multifactorial.
The following are some factors that can cause or contribute towards dry eyes:
- Dietary deficiency
- Dry/ dusty environments
- Computer use
- Inflammatory conditions eg. Rheumatoid arthritis
- Contact lenses
- Cosmetic laser surgery
The tear film is composed of a balance of 3 layers working together to provide nutrients, lubricate and defend the eyes. A deficiency in any of these layers can lead to a breakdown in the tear film, causing dry eyes or watery eyes.
The quantity and quality of the tears as well as normally functioning accessory glands and ducts and contribute to a good balance and normal function.
Under production or over evaporation of tears, or pathology of any of the accessory glands and ducts will give rise to a tear film abnormality.
If you experience any of the following, you should consider having a dry eye assessment.
- Do you feel your eyes are sandy or gritty?

- Do you have red eyes?
- Do you feel any discomfort when you work with a computer or tablet?
- Do your eyes sting or burn?
- Do your eyes itch?
