What are the vision requirements for a commercial pilot?

The vision requirements for a commercial pilot are established to ensure that pilots can effectively operate an aircraft and respond to visual cues essential for flying. A distant vision of 20/20 or better in each eye, whether corrected with glasses or contact lenses or not, ensures that pilots have adequate visual capabilities to identify instruments, read charts, and see other aircraft or ground features during flight. This standard helps maintain safety in aviation, as good vision is critical for navigating and avoiding obstacles.

While some options present varying standards, they do not adhere to the specificity and stringency that the correct standard provides. For instance, having 20/30 vision in both eyes may not be sufficient for the complex visual tasks pilots regularly encounter. Also, the absence of specific vision requirements would compromise safety in aviation operations. Therefore, the requirement that pilots maintain 20/20 vision in each eye, with or without correction, is crucial for meeting the demands of flying and ensuring safety in all operational scenarios.
