Hello Aspirant,

According to the eligibility criteria of NDA, you cannot give NDA exam if you have 3.5 D myopia. The physical standards set by NDA are as follows:

• The distance vision should be 6/6 in the better eye and 6/9 in worse eye
• Myopia should not be more than 2.5D
• Hypermetropia should not be more than 3.5D including Astigmatism

Hope it helps!
