What is one of the main risks associated with wearing contact lenses improperly?

Wearing contact lenses improperly can significantly increase the risk of eye infections, which is a serious concern for anyone using corrective lenses. When contact lenses are not used according to recommended guidelines—such as failing to clean them properly, wearing them for extended periods, or using lenses that are not prescribed—bacteria and other pathogens can accumulate on the lenses or in the eye. This can lead to conditions like keratitis, which is an infection of the cornea that can cause pain, blurred vision, and in severe cases, result in permanent vision loss.

Conversely, the options that discuss increased comfort, enhanced vision, and improved focus do not directly relate to the risks. While proper use of contact lenses can provide comfort and improve vision, improper usage ultimately poses threats that outweigh any temporary benefits. Therefore, understanding the risks associated with improper contact lens wear is crucial for maintaining eye health and preventing infections.
