To test your eyes for NDA, first check distance vision using a Snellen chart; stand 6 meters away and read each eye separately—NDA usually requires 6/6 in one eye and 6/9 in the other. Next, test near vision by reading small text at 14–16 inches; normal is N5 or N6. Check color vision with Ishihara plates to detect red-green color blindness. Also, observe eye movements and peripheral vision for alignment and full field of vision. Minor corrective lenses may be allowed for some entries, but Air Force Pilot requires unaided 6/6 vision. Finally, a professional eye checkup is recommended for official NDA eligibility.

Hello

To test your eyesight for the NDA exam, you can start with a simple self-check at home by reading letters or numbers from a distance like using an eye chart or even a newspaper. Make sure both your eyes can see and distinguish details without strain. It’s also important to visit an eye specialist for a professional vision test, as they can measure your clarity of vision and check for any issues like color blindness or depth perception problems that the NDA requires. Regular practice and timely check-ups will help ensure your eyes are in good shape for the exam.
