Eye Care – Dry Eyes
Dry eye syndrome, also known as keratoconjunctivitis sicca, occurs when the eyes do not make enough tears or the tears evaporate too quickly. Eyes dry out and become red and swollen and irritated. Dry eye syndrome is a common complaint and can affect people of any age, but the chances of developing dry eye syndrome increases as you get older.
Common Causes
The natural ageing process
Problems with blinking or problems with the glands which produce tears
Some Medication such as antihistamines or oral contraceptives
Wearing contact lenses
Living in a windy or hot climate
Hormonal changes, such as during menopause
Symptoms of Dry Eye
Eyes that feel dry, gritty and sore and these symptoms worsen over the course of the day
Foreign body sensation
Eyelids stuck together upon waking up
Temporarily blurred vision, which usual improves upon blinking
Red Eyes
Reducing the symptoms
Lowering the temperature indoors – high temperatures make the tears evaporate more quickly
Central heating can make the air quite dry and sitting directly in front of a heating source like the fire can cause symptoms
Sometimes humidifies can help by moistening the air
Many people find that dry eye is worse during tasks such as reading or computer work. This is usually because we unconsciously blink less when we are doing anything that needs lots of visual attention
Artificial Tears
Artificial tears in the form of drops are usually the mainstays of treatment for people with dry eye. The aim of the treatment is to supplement the tears and therefore make the eye more comfortable. They also stop any damage to the front of the eye from a prolonged period of dryness
Advice for using Eye Drops
Don’t share your eye drops with anyone else
Patients using contact lenses should use a preservative free lubricant
Many eye drops and gels should be thrown away 28 days after opening, but some newer eye drops can be kept for up to six months after opening – be sure to read the box!
