Asked in Health, HIV and AIDS
Can you contract HIV through eye tears?
While transmission could be possible, tears are probably the body fluid least likely to harbor the virus. Tears contain both salt and components that actively fight against microorganisms of all kinds. Out of all the microbes that your eyes come in contact with nearly constantly, only a few can survive long enough or in sufficient quantities to cause an infection.
Asked in Human Anatomy and Physiology
How does tears protect the body from diseases?
Tears contain an enzyme called lysozyme. This enzyme is able to destroy the cell walls of certain bacteria, thereby protecting the body from infection by these organisims. It can also protect the body from infection by constantly flowing, flushing out the eye and preventing entry of these organisims into the body.
