Hello Aspirant,

No you cannot apply for NDA because as per the eligibility criteria for NDA, permitted limit for Myopia is -0.75 but you have -4 so you have exceeded the limit, therefore you will not be eligible neither for Indian Army nor for Indian Navy as well as Air force.

You can check out detailed eligibility criteria along with all physical standards requirement from the link given below :-

I hope this information helps you.

Good Luck!!
