Corneal ulcers are indeed a potential complication of contact lens wear due to the nature of contact lenses' interaction with the eye. When contact lenses are improperly fitted, not cleaned, or worn for extended periods, they can reduce the amount of oxygen that reaches the cornea. This lack of oxygen, combined with the presence of bacteria or other pathogens, can lead to inflammation and infection of the cornea itself, resulting in a corneal ulcer.

Corneal ulcers can be serious and may lead to vision loss if not treated promptly. The risk factors associated with contact lens wear, such as the environment (e.g., swimming with lenses), poor hygiene practices, and wearing lenses overnight, can exacerbate the likelihood of developing these ulcers. Being aware of these risks is crucial for anyone who wears contact lenses, emphasizing the importance of proper lens care and adherence to wearing schedules prescribed by eye care professionals.
