ect the best evidence to support the statement that crying can protect your eyes. Dust and dirt can make your eyes itchy and damage the delicate surfaces. Eyelashes act as filters, keeping many particles away from the surface of the eye Tears wash over the eyes to clean them. Tears also contain an enzyme, called lysozyme, that destroys bacteria. Saliva in your mouth washes over your teeth to clean them. It also prevents microbes from growing inside your mouth. Your stomach can usually deal effectively with any microbes that enter it. The digestive juices inside your stomach are extremely acidic, and will kill most microbes. If toxins enter the stomach, you may vomit to expel them from your body. Toxins and microbes that get past your stomach defenses travel on through your digestive system. From Carol Ballard, The Immune System. Copyright 2003,2009 by Heinemann Library

Tears are not just a way to express emotions; they play a critical role in maintaining eye health! When we cry, tears wash over the eyes, removing dust, dirt, and other irritants that can cause discomfort or potential damage. In addition to providing moisture, the tears contain lysozyme, a powerful enzyme that works tirelessly to destroy bacteria, helping to protect our precious peepers from infections! Not only do tears provide a natural clean-up crew for your eyes, but they also keep them lubricated, which is essential for comfort and clarity. When you experience irritation, be it from crying or just your body’s response to an allergy, this protective tear action can help soothe inflammation and promote healing. So, the next time you shed a tear, remember that your eyes are getting a little pampering session too!
