Tears are necessary to keep our eyes moist and healthy. Tears lubricate eyes and make it possible to see the world clearly. When you blink a tear film spreads over the eye, this film is made up of three distinct layers including oil, water and mucus.
- Oil – this is the outermost layer of your tear and serves as a protective layer to help prevent your eye from drying out. Various fats in the outer oil layer slow evaporation.
- Water – the water layer in your tears is generally the thickest layer and contains electrolytes like potassium and sodium as well as glucose and proteins which are mostly enzymes.
- Mucin or mucus layer – the mucin layer is the layer of your tear which is directly in contact with the surface of your eye. This layer not only lubricates the eye but also provide nourishment to your eyes as well.
The specific composition of tears may change day to day and depend on your general health and other conditions. When your tears oare out of balance, it can lead to other issues with your eye such as dry eyes.
