Wearing lenses in high altitudes and dry environments may result in complaints of all but which of the following?

Wearing contact lenses at high altitudes and in dry environments can lead to various discomforts primarily due to environmental factors that affect tear production and the overall health of the cornea. Pain, grittiness, and burning sensations are common complaints in such conditions because the lenses can become dry, leading to irritation or discomfort in the eyes.

Chalazion, on the other hand, is a condition characterized by a blocked oil gland in the eyelid, which can lead to swelling and tenderness but is not directly related to the wearing of contact lenses in high-altitude or dry settings. Instead, it is typically caused by inflammation or blockage associated with gland dysfunction, often independent of external environmental factors affecting lens wear. Thus, this specific discomfort is less likely to be a direct result of the conditions associated with high-altitude or dry environments when wearing contact lenses.
