After an optician receives a correctly completed prescription, within how many days should aircrew be seen?

• A. 2 days
• B. 3 days
• C. 4 days
• D. 5 days

Answer: (B)

When aircrew need updated vision, getting timely follow‑up is essential for safety and flight readiness. Once the optician has a correctly completed prescription, the goal is to have the aircrew seen within a short, standard window so that the new glasses or lenses can be fitted and any necessary checks completed without keeping them out of service for too long. The recommended timeframe is three days. This strikes a balance between scheduling practicalities and the need to minimize downtime, ensuring vision is properly corrected well in advance of flying duties.

Choosing a shorter window, like two days, often isn’t feasible because clinics, fittings, and any required medical review take time. A longer window, such as four or five days, increases the period aircrew are out of service with incomplete correction, which can impact mission readiness and safety.
