Dry Eye and its Symptoms

Dry Eye Syndrome is a condition where the eye does not produce enough tears, or the tears evaporate too quickly. People who have chronic Dry Eye Syndrome experience symptoms that include:

What causes Dry Eye?
Dry Eye Syndrome occurs for a number of reasons, the most common of which is the ageing process: approximately 20% of people over 55 suffer from dry eyes.
The surface of the eye (cornea) is very delicate and sensitive, and needs constant lubrication. It gets this by tear production – every waking second your eyes produce a complex mixture of antibiotic lubricants. On average, the volume of tear production is less then half at age 65 than at 18.
Blinking spreads tears over the eye’s surface and they are then drained through two small holes in the corners of the eyelids close to the nose. These tear ducts (puncti) drain the excess tears to the nose and throat. Sometimes the tear supply is insufficient or the puncti drain too much tear coverage, and this can result in Dry Eye Syndrome. Also, activities that decrease blink rate can have an effect.
Other factors that contribute to Dry Eye Syndrome include:

Dry Eye Syndrome is not an infection, but it can sometimes lead to infection if left untreated. Please contact Dry Eyes Expert for further advice.
