"Tears" .... no ordinary tears !!

William Frey, a scientist, has been researching tears for about 15 years. At the end of the study, he said:

"Tears are not ordinary. It is a complex mixture of water, mucus, oil, electrolyte. . It is resistant to bacteria, which protects the eyes from infection. It smoothes the cornea, which is vital for clear vision. . It keeps the cornea moist enough and provides oxygen. . It acts as a wiper for the eyes, which washes the eyes and cleans them from dust. " . If the tears were just water, it would dry and burn the eyes due to friction. If the temperature in winter was zero degrees, the water would dry up and freeze into ice! . Again, if the tears were just a kind of oil, it would not clean the dust of the eyes, but would make it more cloudy. . Tears have been used in nature from millions of ingredients, a special blend of which can simultaneously clean, smooth and disinfect and provide oxygen. . Just thinking about this tearful thing makes the head bow in gratitude to the Creator. .
