Dry eye is a common condition. Dry eyes occur when the eyes don’t make enough tears, or the composition of the tears is abnormal and cannot cover the surface of the eyes sufficiently well.
Dry eye syndrome is more common in women than men. The incidence of dry eye increases with age due to the natural ageing process. Hormonal changes in women e.g. the menopause, also influence dry eye symptoms.
Other factors include
- Environmental conditions including air-conditioning, central heating. Windy weather and smoky environments can induce quicker tear evaporation
- Medications: the oral contraceptive pill, anti-depressants and antihistamines, beta-blockers and diuretics
- Looking at electronic screens for long periods of time
- Contact lenses dry eyes out
An uncommon cause of dry eye is Sjogren’s syndrome.
