How can contact lenses damage your cornea?

ANSWER

Contact lenses can damage your cornea in many ways.

? Scratches on the edge of your contact lens can scrape the cornea’s surface and make it more open to bacterial infections.

? Similarly, tiny particles of dirt trapped underneath the contact lens can scratch the cornea.

? Bacteria may be on the lens or in your cleaning solutions and, thus, get trapped on the undersurface of the lens. If your lenses are left in your eyes for long periods of time, these bacteria can multiply and cause damage to the cornea.

? Wearing lenses for extended periods of time can also block oxygen to the cornea, making it more susceptible to infections.
