Eye
Read the official ruleThis regulation sets the vision standards for a second-class medical certificate (required for commercial pilot operations).
Distance vision: You must have 20/20 vision or better in each eye, with or without glasses or contacts. If you need corrective lenses to meet this standard, you must wear them while flying.
Near vision: You need 20/40 or better at 16 inches in each eye. If you're 50 or older, you must also meet 20/40 at 32 inches to ensure you can read both instruments and charts comfortably.
Other requirements: You must perceive colors necessary for safe flight operations, have normal peripheral vision, and be free from eye diseases that interfere with vision or could worsen with flying.
The regulation also addresses eye alignment issues (phorias). If your eyes show certain misalignment values during testing, the FAA may require an eye specialist evaluation, though you can receive a temporary certificate while awaiting results.
