Why Should You Avoid Rubbing Your Eyes?

Though it may seem harmless, rubbing your eyes is something many of us do from time to time. Doing so feels good because it stimulates tear flow and eye lubrication, which offers relief for dry eyes and helps remove dust and other irritants. Furthermore, rubbing your eyes can be therapeutic, as pressing down on your eyeball stimulates the vagus nerve, which decreases your heart rate, thus relieving stress. 

Continuous eye rubbing in susceptible individuals can cause the cornea to thin and weaken, leading it to bulge forward and become more cone-like. This is known as keratoconus which is a serious condition that can lead to distorted vision and ultimately the need for a corneal transplant or specialized contact lenses, such as scleral lenses.If you have a foreign object in your eye, your natural instinct is likely to rub it in an attempt to remove the object. However, this can potentially cause more damage as the object can scratch the cornea. Instead, try flushing it out with saline solution or artificial tears. 

When your eyes are itchy, it is tempting to rub them. But rubbing releases histamines, which make the itching worse, which in turn leads to more aggressive eye rubbing. Rubbing your eyes isn’t all bad. It releases more tears, which in turn causes the meibomian glands, situated within your eyelids, to secrete much-needed oil into our eyes. That adds moisture and protects our tears from evaporating. 

In summary, excessive eye rubbing, whether due to chronic dry eye, itchy eyes, or habit, should be addressed to prevent any ocular and vision damage. Contact Complete Eye Care at Belmont to schedule a visit, determine the cause of your itchiness, and find out which drops to use in your specific case.
