If either eye becomes red or painful, aircrew should cease wearing SCL and see a MO within how many hours?

• A. 6 hours
• B. 12 hours
• C. 48 hours
• D. 24 hours

Answer: (D)

Prompt medical evaluation for eye symptoms in aircrew who wear contact lenses is essential because redness or eye pain can indicate a vision-threatening problem such as infection or corneal injury. The recommended course is to stop wearing the soft contact lenses and see a medical officer within 24 hours. This timeframe allows timely assessment and treatment of conditions like keratitis or corneal ulcers, which can worsen quickly and threaten sight if left unchecked. Early evaluation helps determine the appropriate management and when it’s safe to resume lens wear or return to flight. If symptoms are severe—significant pain, vision changes, or light sensitivity—seek urgent care immediately.
