What infection are contact lens wearers particularly at risk for?

Contact lens wearers are particularly at risk for infections caused by Pseudomonas aeruginosa due to several factors associated with lens use and care. Pseudomonas is a gram-negative bacterium known for its ability to thrive in moist environments and can form biofilms, making it difficult to eradicate.

When individuals wear contact lenses, they create a warm and moist environment that can enhance bacterial growth. Pseudomonas is also known for its virulence, especially in corneal infections, which can lead to serious complications like keratitis. This is particularly true for improper lens hygiene, wearing lenses for extended periods, or exposure to contaminated water sources, such as swimming in pools or showering while wearing lenses.

Other pathogens may also cause infections in contact lens wearers, but Pseudomonas is notorious for being particularly aggressive and is often associated with severe ocular infections in these individuals.
