Explanation:

Eyes are also protected by tears, which moisten them and clean out dirt, dust, and other irritants that get past the defenses of the eyelashes and eyelids. Tears also help protect against infection. With each blink, our eyelids spread a layer of mucus, oil, and tears over the cornea, which covers the front of the eye.
