Eye Lubrication: What You Need to Know
The eyes need a healthy level of eye lubrication to help keep them functioning properly. Eye lubrication helps keep the eyes moist, reduces irritation, and helps prevent eye infections. Without adequate eye lubrication, you may experience blurred vision, redness, and discomfort.
The eyes produce two forms of eye lubrication: tears and meibum.
Tears
Tear production is part of the body’s natural reflex reaction in response to airborne particles, irritants, and general eye stimulation. Tears are composed of three layers of fluid: an oily layer, a watery layer, and a mucous layer.
The oily layer of tears is secreted by the outer edge of the eyelids. It helps decrease evaporation and increases the tear’s lifespan. It also helps to reduce glare, allowing more light to enter the eye.
The watery layer is secreted by the lacrimal glands and helps keep the eye moist. It also keeps the cornea healthy and functioning properly.
The mucous layer is secreted by the conjunctiva. It helps keep the surfaces of the eye lubricated and helps to decrease friction between the eye and the eyelid.
Meibum
Meibum is a form of oil that is secreted by the meibomian glands. It is an important part of eye lubrication, as it helps to keep the surface of the eyes moisturized and resistant to bacteria. Without adequate meibum production, the eyelids may appear red and dry.
Meibum can be artificially added to the eyes in the form of eye drops. Artificial tears can help to improve the eye’s moisture balance and reduce dryness.
Treating Dry Eyes
If you are experiencing dry eyes, there are a number of treatments available to help reduce the symptoms. These treatments include using over-the-counter eye drops, taking oral medications, and using moisture chambers. Additionally, your doctor may recommend surgery to repair an eyelid that is not able to close properly, or to remove any obstructions that are preventing adequate lubrication.
Tips for Healthy Eyes Lubrication
- Avoid smoke and other irritants, as these can dry out the eyes
- Wear protective glasses or sunglasses when outdoors
