Thousands of young students aspire to join the Indian Defence Forces every year by preparing for the NDA examination. They prepare well, study hard, and then one question comes at them, and it paralyses them – “I wear spectacles.” Is it still possible to apply for NDA 2026? If this is your question, you are in the right place. This blog will discuss NDA eyesight requirements, NDA medical standards, and NDA eligibility criteria in layman's terms. The best NDA books of 2026 will also be shared with you to prepare well.

What is an NDA, and Who Can Apply?

NDA is the acronym for National Defence Academy. UPSC holds this exam twice a year to recruit officers for the Indian Army, Navy and Air Force. The age limit for appearing in the NDA exam is 16.5 to 19.5 years, and the candidate should be a male citizen of India to be eligible for the exam in 2026. You should have passed in or be appearing in class 12. In class 12th, Physics and Mathematics are compulsory for the Navy and Air Force. You will also need to be single and physically healthy to the standards of the NDA.

NDA Eyesight Requirements – Branch-wise Standards

The medical board tests your distance vision with no glasses or contact lenses. The standard is different for each branch. The complete list of NDA eyesight requirements by branch:

The Navy is the most demanding, with a 6/6 vision in both eyes. All branches test unaided vision only. An eye test is not to be done with spectacles or contact lenses.

Can You Apply for NDA With Spectacles?

This is the most frequent question, and the truthful answer is – wearing spectacles does not automatically exclude you. The important thing is your unaided vision (without glasses). You may still pass the medical exam if you can see the table above with your natural vision without spectacles. 

If your unaided distant vision is below the standard – for example, 6/24 or worse – then you will be deemed medically unfit for that branch. Contact lenses are also not allowed to be worn during the test, and therefore cannot be used to help you improve your score. Have your eyes checked by a doctor first to find out where you stand.

NDA Medical Standards for Eyes – Full Checklist

The NDA medical standards test is about more than just distant vision. The medical board reviews the following information:

Colour vision is especially important for the Air Force. The Martin Lantern Test is used to determine the CP-I grade which is acceptable for flying. A candidate will not be accepted for the Air Force if they have any type of colour blindness.

Is LASIK Surgery Allowed for NDA?

Yes, NDA can have LASIK surgery, but under certain conditions. If the surgery has been performed at least 12 months before the medical examination, the Army and Navy will accept the surgery if the eyes are completely stable and there have been no complications. The rules of the game have been changing in recent years for the Air Force pilot job, so it is always better to check the latest official notification released by UPSC for the NDA before making any decision. Consult a qualified eye specialist before going for surgery with the aim of meeting NDA eyesight requirements.
