Tears are a vital defensive agent for the eyes. They not only help the eyes in getting rid of the dust, but also relieve the eyes from discomfort. In addition, tears also furnish the cornea with oxygen and nutrients, and also assist in averting eye infections. Tears consist of three dissimilar layers. The outer lipid layer comprises an oily film that checks evaporation and keeps the eyes lubricated. The middle layer consisting predominantly of water, moisturizes the eyes and also contains some nutrients and proteins that assist in curbing eye infections. The inner layer is made up of mucous that aids the tear film to spread and remain on the eye. Every layer is vital for the wellbeing of the eyes.
