Did you know the human eye produces 15 to 30-gallons of tears each year? Well, that’s for a valid reason too!
Tears are a complex liquid made from water, oils, mucus, antibodies, and special proteins. And, although we only see them while crying, these tears keep our eyes lubricated at all times. The liquid acts as a lubricant for better vision and comfort.
However, at times, this tear system becomes dysfunctional. Or, in simple terms, your eyes are unable to produce sufficient tears. As a result, your eyes become itchy and red.
Your vision may become blurry and light-sensitive. It might feel as if something has got in your eyes. A condition like this is what we call dry eyes. Continue reading to unravel the details:
What is the Cause of Dry Eyes?
As mentioned, the fundamental reason behind dry eyes is the disruption of the healthy tear system. However, there can be several different types of problems that can make the tear film of the eyes dysfunctional. The two common ones include:
Decreased Tear Production
It occurs when eyes are unable to produce sufficient tears. It may be a result of aging, medication, or medical conditions like Sjogren's syndrome.
Increased Eye Evaporation
The glands responsible for producing the oil film in the tear system get clogged. It can lead to increased evaporation and drying of the eyes. Eye allergies, blinking infrequently, wind, smoke, vitamin A deficiency, and several other reasons may trigger this disruption.
All that said, most individuals with dry eyes are either over 50-years-old, poor eaters, or contact lens users. Women suffering from hormonal changes are more likely to develop dry eyes.
Are Dry Eyes Curable?
Dry eyes usually last around three to six months. However, during this time, the eyes must be treated to prevent permanent damage. Here are some of the dry eyes treatments that a doctor will use:
1. Artificial Tears
There are several artificial tear drops available in the market. You will have to apply it to your eyes according to the prescribed frequency. If your eyes are severely dry, your doctor may ask you to apply a thick ointment.
2. Punctual Occlusion
Punctum refers to the tear duct that takes the excess tears from the eyes to the nose. In punctual occlusion, the doctor will close this duct using either temporary or permanent plugs. It helps restore tears to normal levels without the continuous use of artificial tears.
3. Lipiflow
Lipiflow is a medical device that unclogs the blocked glands using heat and pressure. Hence, the risk of evaporation and dry eyes becomes less.
Apart from treatments, you can also restore your tear production by improving your diet. Food items, like fish oil, can help improve eye health. You can also get a humidifier to add moisture to the environment and ease your eyes.
Conclusion
In a nutshell, dry eyes are a serious condition that can cause permanent damage to your vision. If you ever experience itchy dry eyes, be sure to contact a medical expert and seek treatment immediately.
