Tears are made of salt and water. The gland (its called the lachrymal gland, derived from the Latin word 'tear') that provides the eyeball with moisture to rotate in a proper way. 

When this gland produces more water than usual, it results in the formation of tears as the eye cannot imbibe in the extra supply of water and ergo overflows. 

The water in tears acts as a lubricant, and the saline property helps prevent bacterial infection.
The lachrymal gland is the size of an almond nut and is situated above the eye. There are six or seven ducts that provide the opening for the lachrymal gland to the eyeball. Each blink of an eye causes the water to spread evenly over the eye. Extra water is stored in two tiny canals at the inner corner of the eye.

The lachrymal gland secretes an extra supply of water when one experiences some a little too intense than usual – like a strong smell, for instance, ammonia or garlic or onions or in the emotional aspect, a situation of enormous emotional strain be it delight or melancholy.

The eye tears are the drops of the clear salty liquid that is secreted by the lachrymal gland of the eye to lubricate the surface between the eyeball and eyelid and to wash away irritants.
