It is estimated that dry eye symptoms are experienced by 1 in 5 adultsin the UK


Dry eye disease occurs when the eyes either do not produce enoughtears or the tears evaporate too rapidly. Our eyes, just like our skin or hair, are affected by harsh, drying environments, as well as being sensitive to long periods of concentration at a computer screen or reading. Physical activities such as driving, cooking, and running can also be problematic. Modern lifestyles and an increased amount of time spent looking at screens2 means the symptoms of dry eye are no longer only associated with the elderly.


Symptoms of dry eye can range from uncomfortable, tired or itchy eyes3 to more bothersome symptoms such as a burning or gritty sensation or persistent watery eyes. It is common to experience these sensations from time to time but when frequently occurring, they may leave you with an overall sense of fatigue.

Dry eye generally occurs in both eyes at once. If symptoms or redness are much greater in one eye than the other, further ophthalmic investigation is required.4
