Mr Nys,
The eyesight requirements for all three services are taken from the same publication and are identical.
The fact is they are different for those going to other roles than FJ pilots. If you apply to the RN you will need to see an optician for a pre-test which WILL decide whether you can apply or not.
The comments about training are correct (there is NO difference in pipeline time RAFvs RN).
