What could be causing my dry eyes?

Dry eye syndrome occurs when the eyes do not make enough tears or the tears evaporate too quickly. The eyes dry out and become inflamed and irritated and may cause blurred vision. According to Mr Saj Khan, consultant ophthalmic surgeon for the London Eye Hospital, dry eyes are commoner in women than in men.

“They typically get worse as people get older, especially at the menopause,” he says. “Other common triggers include wearing contact lenses, autoimmune conditions, such as rheumatoid arthritis, and certain medicines, such as antihistamines, antidepressants, blood pressure medications or the oral contraceptive pill.”

Symptoms are often worse when concentrating (e.g. reading/ driving) or in windy environments, including when air conditioning or heaters are blowing. Mild to moderate cases of dry eye syndrome can usually be successfully treated with OTC eye drops, gels and ointments that contain ‘tear substitutes’. Useful tips include lowering the temperature in rooms, blinking more often while reading or using the computer, and avoiding smoky environments.
