What are they and why do they arrive when we’re feeling miserable? I.e. what is the reason for them being produced? if its ‘cleaning’ well thats pointless as a person who never cries wouldn’t get them hence their purpose for him would be useless.
Explain

Re: Tears
Wikipedia :Tears are the liquid product of a process of crying to clean and lubricate the eyes. The word lacrimation (from L. Lacrima meaning Tear) (also spelled lachrymation) may also be used in a medical or literary sense to refer to crying. Strong emotions, such as sorrow or elation, may lead to crying. The process of yawning may also result in lacrimation.

^ Ahh you found it! 
So there are different types of tears…the reflex kind which we cry when we want to ‘cleanse’ the eye and the ones associated with emotions.
Re: Tears
So we cry..when we want to cleanse out eyes? So for people who don’t cry then that means we don’t want to clean our eyes? 
A cry smiley, how ironic!
