Final answer:
Having bad eyesight may disqualify someone from becoming a commercial pilot, as visual acuity is important for safe flying. However, there are options available for individuals with less than perfect vision.
Step-by-step explanation:
Having bad eyesight can potentially disqualify someone from becoming a commercial pilot, as visual acuity requirements are necessary for safe flying.
The Federal Aviation Administration (FAA) in the United States requires a minimum visual acuity of 20/20 or corrected to 20/20 in each eye. Some other countries may have slightly different requirements.
However, there are some options available for individuals with less than perfect vision, such as wearing corrective lenses or undergoing vision correction surgery.
