Expert Answer:

Tears are produced by the accessory lacrimal glands, located in the upper eyelid, and the main lacrimal gland, located just above the eye.  These structures secrete tears onto the front surface of the eyes, which then drains, and finally travels down into the lacrimal duct located near the nose.

The physical act of crying is a combination of neural activity in the brain that is associated with emotion and its connection to the lacrimal system, the orbital structure that produces and drains tears.

As long as the lacrimal sacs are not removed or destroyed, the people without eyesight will still produce tears. Since the tear ducts are not attached to the eyeball, the tears produced go through the tear ducts into the eye sockets and nasal cavity.
