What can an incorrectly fitted contact lens cause?

An incorrectly fitted contact lens can lead to discomfort and potential eye damage due to several factors. When a lens does not fit properly, it may not align correctly with the curvature of the cornea, which can cause irritation, redness, and pain. This improper fit can also lead to friction between the lens and the eye's surface, potentially resulting in corneal abrasions or infections. Over time, consistent discomfort can lead to more severe issues, including decreased vision and long-term damage to the eye.

A well-fitted contact lens is crucial for maintaining not only comfort but also the overall health of the eyes. An improper fit can compromise the protective tear film on the eye and create areas where debris and bacteria can accumulate, increasing the risk of serious complications. Thus, ensuring that contact lenses are fitted correctly is vital for both comfort and the health of the eyes.
