What operations are soft contact lenses not operable with?

• A. CBRN
• B. Radiation
• C. Surgical procedures
• D. Blood tests

Answer: (A)

In hazardous environments, protecting the eye from chemical, biological, radiological, or nuclear agents is crucial. Soft contact lenses can trap contaminants and absorb irritants, making decontamination harder and increasing the risk of exposure when the lens is handled or removed. They can also interfere with the proper seal of protective eyewear, potentially letting hazards reach the eye. For that reason, soft contact lenses are not suitable in CBRN operations, and proper eye protection is used instead. In other scenarios like imaging or sterile procedures, standard protocols may require lens removal for safety or sterility, but the unique risk in CBRN settings centers on contamination control and effective eye protection.
