Everyone has cried real tears. When you stub your toe or fall off your bike, you probably cried many tears. What are tears made of, and why do we have them? Tears are a liquid made up of water, salt, glucose, and many other ingredients. This tear fluid is good for your eyes. Tears keep your eyes clean and lubricated. That means they keep your eyes from drying out. Tears can clean dust and sand out of your eyes, and they can help your eye heal when it gets scraped. There are three types of tears: basal tears, reflex tears, and emotional tears. Basal tears keep your eye wet and nourished. Reflex tears help repair your eye from injury, and emotional tears flow from your eyes when you are sad.
