Tears are made up of an amalgam of water, mucus and fatty oils. This mixture is necessary for the eye to function properly and for the eyes to remain clear, smooth and free from infection. Dry eyes are caused by insufficient tears. If the eyes are not kept comfortably lubricated, this can lead to dry eyes. Dry eyes syndrome is also known as KCS or keratoconjunctivitis sicca. This is a common disorder that affects a large percentage of the population but is easy to treat with artificial tears, eye exercises and a healthy eating plan. There are several things to be aware of when considering whether you have dry eyes.
A person may experience burning, itching, redness or a gritty feeling in the eye area. They may also experience blurred vision and sensitivity to light. It is also quite common to feel as if there is debris in the eye. You may also experience watery eyes. As the eye becomes dry it may, as a reflex action, initiate a large amount of tear production all at once. Tears will actually pour from the eyes, but this does not help the eye at all. The eyes will become dry again and the excessive tear production process will be repeated.
Harsh windy or dry conditions can make dry eye symptoms worse. Be aware of your surroundings, and if you are in a climate with low humidity but with a higher temperature, you may find that your dry eye symptoms worsen.
If you have difficulty blinking, inadequate tears may be spread across your eye or the tears may disperse too quickly, causing dry eye syndrome. If you are spending prolonged hours in front of a computer screen or watching too much television or even reading for long periods of time, these activities will cause you to blink less. Long hours spent driving is another factor that can cause dry eyes. Decreased blinking leads to tear evaporation and as a result, this will lead to dry eye syndrome.
If you are taking medication for hormones, acne, antidepressants, high blood pressure, birth control, beta blockers or antihistamines, these can all cause dry eyes. Speak to your doctor to see if your medication could be causing your dry eye symptoms. Certain medications will cause a decrease in tear production.
Inflammation or infection of the eyelid can lead to dry eye syndrome. Blepharitis, or inflammation, is a common condition that is easily treated.
Dry eye symptoms affect a large percentage of the population. Dry eyes can cause difficulty with work, discomfort and have a detrimental effect on your general health, as well as your ocular health. Dry eye can be annoying but peruse Allergan Dryeye.com.au for information on dry eyes and general eye health.
