Hello student,

I think there isnt any issue for an eyesight issue in the Indian Armed forces. Any person with a spectacle number under 3 is allowed to join the Armed forces. However, one cannot join the Air Force in case of spectacles of any number. That is strictly the policy there. I would suggest that you still improve your eyesight by doing various eye excercises daily and eat healthy food that would improve your eyesight.

I hope this helps, All the Best!
