Dry Eye

Dry eye is a common condition which occurs either when a person doesn’t produce enough tears, or where the tears evaporate too quickly. Tears lubricate the eyes and keep them comfortable. Anyone can develop dry eyes, but it becomes more common with increasing age. Up to 1 in 3 people over the age of 65 experience dry eye problems and women are affected more often than men.

Treatments are available to help relieve the symptoms, which include eye drops to lubricate the eyes. This is important because a dry eye surface is more prone to eye infections.

Dry Eyes and Blepharitis


Dry Eye Syndrome is strongly associated with Blepharitis, which is like an eczema of the eyelids causing inflammation of the lid margins and tired, gritty eyes. The condition is often caused by the normal bacteria that live on the skin’s surface becoming over active. It can also be caused by Demodex - a naturally occurring worm that lives in the eyelash follicles in the eyelids - the specific causes of your dry eye symptoms will be identified during the eye examination. Treatment involves cleaning the eye lids with a variety of special products which clean or lubricate.

Symptoms


• The eye may not actually feel dry – it could be wet and watery as a result of over tearing in an attempt to combat the dryness
• Gritty, burning or sore eyes 
• Mild redness of the white of the eye 
• Slight blurring of vision from time to time
• Eyelids that stick together when you wake up
• Excess tearing: the eye tries to counteract the dryness by producing extra tears

Causes


Symptoms tend to be made worse by anything which dries out the eyes such as:
• a hot or windy climate
• tobacco smoke
• low humidity; air-conditioning and central heating
• general medication side effects
• eye medication side effects eg diuretics, some antidepressants, antihistamines, contraceptive pills, beta-blockers
• illness such as rheumatoid arthritis or lupus
• hormonal changes
• ageing: less and poorer quality tears are produced as you get older 
• damage to tear glands
• tasks in which one blinks less often can exacerbate the condition e.g. reading or looking at a computer screen or TV for long periods
• Demodex - a naturally occurring worm that lives in the eyelash follicles in the eyelids
