Hello,

For National Defense academy it is required that candidate must be able to read distant vision chart with better eye 6/6 and worse eye 6/9. If you fail in the test you will not be eligibe to join NDA.

Myopia must not be more than -2.5D including astigmatism and manifest hypermetropia not more than +3.5D including Astigmatism.

So it is hard to tell if you can be eligible for applying for NDA.
