Most of us probably only think about tears when we’re crying or expressing emotion. But according to eye doctors, our tears play a vital role in keeping our vision and eyes healthy. From cleaning debris to delivering nutrients, there are a number of different functions our tears serve that concern more than just displaying emotion.

How Tears Benefit Your Eyes

Tears Lubricate the Eyes

Tears aren’t simply “water,” but instead, they contain a mucous layer near the cornea, a saltwater layer to cover the middle eye components, and an outer fat layer that seals everything in. With this system, tears not only lubricate our eyes, but they also protect them from debris or the elements. This is why your eye doctor may recommend lubricated drops if you suffer from dry eyes or wear contact lenses that may not provide enough moisture.

Tears Clean the Eyes

If you get something in your eye, whether it’s an errant eyelash or debris, your eyes will begin to water and flush out the object. In addition to the protection element, the tear film cleans and disinfects the eye using the layer system. The lacrimal glands of the eye ensure tears are continually being produced to clean and flush the eyes out. However, these tears formed by the lacrimal glands are small and do not leak from the eye.

Tears Deliver Nutrients

Much like the blood does for the rest of your body, eye doctors say tears delivery important nutrients and oxygen to the eyes. Because your tears are comprised of different components, they are able to deliver nutrients, oxygen, and remove waste products like blood. Using this system, tears actually help improve the vision of the retina and keep our sight crystal clear. Individuals with dry eyes may notice blurry vision, not simply because they’re not moist, but because these nutrients and oxygen aren’t being distributed properly.
