The Composition Of Tears And Their Role In Eye Health

Dry Eye Syndrome Atasca Eye Center Tears keep the surface of our eyeballs clean and moist and help protect our eyes from damage. tears are made of mucus, water, and oil, and each component plays a role in the eye. mucus coats the surface of the eye and helps bind the tear layer to the eye. without a healthy mucus layer, dry spots may form on the cornea, the clear, dome like. The tear film covers the ocular surface and is essential for protecting the eye from the environment, lubricating the ocular surface, maintaining a smooth surface for light refraction, and preserving the health of the conjunctiva and the avascular cornea. the tear film is approximately 3 to 10 μl in volume, 3 μm thick, and secreted at a rate of 1 to 2 μl min.[1][2] the ph of tears is.

The Composition Of Tears And Their Role In Eye Health The tear film functions to provide a trophic environment to the ocular surface epithelial tissues. integrity and secretory function of the epithelium is important to maintain its role as an innate barrier and “seal” over the extensive network of epithelial free nerve endings (zhou and beuerman, 2012). the lacrimal functional unit (lfu. The oily outer layer keeps tears from drying up too quickly and makes the surface of the eyes smooth. the watery middle layer keeps the eyes wet and nourishes the eye tissue. the inner mucus layer helps the tear film stick to the surface of the eyes. tears keep your eyes wet and smooth, and they help focus light so you can see clearly. Tears are made up of three layers: the oily layer on the outside, the watery layer in the middle, and the inner, mucus layer.the three layers together are known as the tear film.
