tears???and why dont they burn your eyes???

Question

iF TEARS ARE MADE OF MOSTLY SALT WHY DONT YOUR EYES BURN WHEN YOU CRY?

Answer 1

Every part of your body has certain concentrations of salt in it. Your tears, your blood, your tissue, etc. Having salt in something does not mean automatically that it will burn.

Too much salt, on the other hand, will burn. Your body naturally knows what concentration of salt it needs to work, so overproducing only happens when something is wrong.

Tears have numerous components. A little bit of mucus allows them to adhere to the eye surface without causing harm. The main part of a tear contains, predictably, water and salts (like sodium chloride and potassium chloride). The ratio of salt to water in tears is typically similar to that of the rest of the body, so there is no net change in salt concentration; nonetheless, if the body's salt concentration climbs too high, it will take advantage of the tear solution and instill it with extra salt. Tears also have antibodies that defend against pathogenic microbes, and enzymes which also contribute to destroying any bacteria the eye encounters. A thin layer of oil covers the tear's outside to discourage it from falling out of the eye before its work has been done.

Answer 2

No they are made of mostly water. If they were mostly salt they would come out as little salt crystals which obviously doesn't happen.

Seriously speaking there are about 500 compounds in tears including water and fatty acids.

Answer 3

because there's not that much salt in them to make them burn your eyes.
