Do your eyes feel constantly itchy and dry no matter what you do? Are your eyes ready and watery all the time, and you can never get them to stop? You could have a very common eye condition know as Dry Eye Syndrome!
Dry Eye Syndrome: Causes and Symptoms
Sometimes a person is unable to produce enough tears or their tears do not possess the right qualities to keep eyes healthy and comfortable. This can cause a consistent lack of sufficient lubrication and moisture on the surface of the eye.
Normally, the eye constantly lubricates itself with tears by producing them at a slow and steady rate, keeping itself moist and comfortable. Healthy tears will consist of three layers, an oily, a watery, and a mucus layer, with each layer playing a specific role in lubricating your eyes. The oily layer slows evaporation of the tear. The watery layer, which makes up the majority of what a person normally thinks of as tears, cleans the eye and helps to wash away small foreign objects and particles. The mucus layer allows the watery layer to stick to the eye and spread evenly over the eye in order to keep it lubricated.
In a person with dry eyes, either hormonal changes, side effects from medication or some other factor causes the eye to either not produce enough tears, or leave out parts of the tear that make proper lubrication possible.
Symptoms of dry eyes include stinging or burning in the eyes, scratchiness, and excessive irritation from smoke or wind. You may also experience excessive tearing. In this case, the eye is attempting to flush and lubricate itself by producing more tears, but is unable to do so successfully due to the rate of evaporation or inability to spread the tears properly.
Treating and Preventing Dry Eye Syndrome
Although dry eyes are not always curable, your Squamish optometrist may prescribe artificial tears to help with some of the symptoms. Artificial tears are lubricating eye drops that may help with dry, scratchy feeling eyes. Different artificial tears work in different ways. Some help replenish parts of the tear that your eyes are not producing on its own, others help to produce more tears overall. Your Squamish eye doctor will assist you to choose which will help you most.
Some cases of dry eyes are seasonal, such as those which occur as a result of cold, dry winter air. In this case, your eye doctor may recommend wearing sunglasses or goggles when outdoors to reduce your eyes' exposure to the sun, wind and dust. For indoors, your optometrist may recommend an air cleaner and humidifier to take dust out of the air and add moisture to air which is too dry.
Studies have also shown that nutrition may have a part in helping to relieve some symptoms of dry eyes. Your eye doctor may recommend nutritional supplements such as omega-3. Good sources of omega-3 fatty acids are cold-water fish, cod, herring and salmon, as well as flaxseed oil. Mild dehydration can make symptoms worse too, so be sure to drink plenty of water, 100 percent fruit and vegetable juices and milk.
