What is Tears?
[[File:Crying boy.jpg|thumb|Crying boy]] '''Tears''' are clear [[liquid]] made by the body to clean and lubricate the [[eye]]s. There are three different types of tears that the body makes: * ''Basal tears:'' In a normal, healthy [[mammal]], tears are regularly made to clean the [[cornea]] (front part of the eye) and to keep it clean from [[dust]]. * ''[[Reflex]] tears:'' This type of tear is made when something irritates the eye, say, bits of dust or the smell of an [[onion]]. These tears are made to clean the eye and wash out anything irritating it. * ''Emotional tears'' (psychic tears): The last category is called ''[[crying]]'' or ''weeping'', when tears are made because of physical [[pain]] or strong [[emotion]]s. You can produce tears when you cry. [[Category:Eye]]
