What should be done with contact lenses during OC exposure first aid?

• A. Remove contact lenses if present and flush eyes
• B. Do not remove lenses
• C. Leave lenses in and flush eyes
• D. Rinse with water and rub eyes

Answer: (A)

Removing contact lenses if any are present is the best first aid step because lenses can trap OC against the eye and hinder effective irrigation. Once the lenses are out, rinse the eyes with clean water or saline for several minutes to wash away the irritant and reduce ongoing exposure. After removing lenses, continue flushing rather than rubbing, which can irritate or injure the eye. If irritation persists, vision changes, or a lens cannot be removed easily, seek medical help. Keeping lenses in can prolong exposure and worsen discomfort, and rinsing with water while keeping the lenses in is not as effective.
