Bacterial keratitis is commonly seen in which population?

• A. Contact lens wearers
• B. Newborns
• C. People with glaucoma
• D. Athletes

Answer: (A)

Bacterial keratitis is most strongly linked to contact lens wear. The lenses can cause tiny injuries to the corneal surface and, if hygiene is poor or lenses are worn overnight, create an environment where bacteria—especially Pseudomonas aeruginosa—can invade the cornea and cause infection. While newborns can develop eye infections and people with glaucoma or athletes can have other ocular issues, they are not the population most commonly affected by bacterial keratitis. Therefore, the group most commonly seen with this condition are contact lens wearers.
