As we grow, we experience more dry eye symptoms. The biggest reason people have dry eyes is that the tear film doesn’t have the right consistency of water, mucus and oil. The oil part of your tears comes from little glands at the margin of your eyelids. As you blink, oil is supposed to coat the eyes.
