What is a side effect of taking decongestants that can affect contact wearers?

Taking decongestants can lead to corneal dehydration, which is a significant concern for contact lens wearers. These medications often have a drying effect on mucous membranes, including those in the eyes. This dehydration can result in discomfort, dryness, and reduced lubrication under the contact lens, potentially making it difficult for the lens to stay hydrated, which is critical for comfort and vision clarity.

When contact lens wearers experience corneal dehydration, they may notice increased irritation, blurred vision, or an overall negative impact on the wearing experience. Maintaining moisture is essential, as dryness can cause the lenses to adhere more to the cornea, leading to further discomfort. Understanding this side effect helps contact lens users manage their eye health effectively while undergoing treatment that may involve decongestants.
