Contact lenses are most likely to be contraindicated for what kind of patient?

Contact lenses may be contraindicated for a patient who is routinely exposed to excessive amounts of fumes or dust due to the potential for irritation and contamination. Such environments can lead to particulate matter becoming trapped under the contact lenses, which could cause discomfort, increase the risk of eye infections, and overall complicate the wear of contact lenses.

In patients exposed to irritants, lenses can exacerbate issues by restricting oxygen flow and trapping harmful materials against the eye. Proper hygiene and maintenance of contact lenses are crucial, and a patient in a hazardous environment might not be able to maintain the necessary standards, making contact lens wear less safe and suitable.

Although other options may present challenges for contact lens wear, they do not carry the same immediate risks associated with environmental exposure to irritants and contaminants as seen in option B.
