The eye maintains a constant level of lubrication through a combination of several mechanisms that work together to ensure the surface of the eye stays moist and protected. Here's an explanation of the main components involved in maintaining the lubrication of the eye:

1. Tear Production: The lacrimal gland, located above the outer corner of each eye, produces tears continuously. These tears contain a mix of water, oils, proteins, and other substances necessary for lubrication and protection.

2. Tear Distribution: Every time you blink, the eyelids spread the tears evenly across the surface of the eye. Blinking helps distribute the tears and keeps the eye moist. It also helps remove debris and irritants that may have entered the eye.

3. Tear Film: The outermost layer of the tear film is a thin layer of [b]lipids (oils)[/b] produced by the Meibomian glands located in the eyelids. This layer helps prevent evaporation of the tears and keeps the surface of the eye lubricated. The middle layer is composed of the watery component of tears, which provides moisture and nutrients to the eye. The innermost layer is a thin layer of mucus that helps the tears adhere to the eye's surface.

4. Reflex Tear Production: When the eye detects an irritant, such as dust or a foreign object, it triggers a reflex tear response. The lacrimal gland produces a larger volume of tears to flush out the irritant and protect the eye. This reflex mechanism helps maintain the eye's lubrication by responding to potential threats.

5. Corneal Sensation: The cornea, which is the clear front surface of the eye, is highly sensitive to touch and changes in moisture levels. If the cornea detects dryness or irritation, it sends signals to the lacrimal gland to increase tear production, helping to restore lubrication.

6. Feedback Mechanisms: The eye has feedback mechanisms that monitor the quality and quantity of tears on the surface. If the tears are insufficient or of poor quality, the eye can increase tear production to compensate and maintain the desired level of lubrication.

For #1, you can use artificial tears.

For #2, hot compress to unclog oil producing glands.[/quote]
