Which of the following is NOT a function of lubricants for the eyes?

Lubricants for the eyes, commonly known as artificial tears or eye drops, are primarily designed to alleviate dryness and enhance comfort. Their main functions include providing additional moisture to the surface of the eyes, which helps to soothe irritation and make wearing contact lenses more comfortable. They also work to enhance comfort by creating a protective barrier on the surface of the eye, thereby easing irritation caused by environmental factors such as wind or smoke.

While lubricants can improve the overall comfort of the eyes, they do not have a direct role in reducing inflammation. Inflammation typically requires specific anti-inflammatory medications or treatments rather than just lubricating solutions. Thus, the function of reducing inflammation is not associated with the primary action of lubricating eye drops, making this the correct answer to the question regarding which function does not pertain to eye lubricants.
