Railway recruitment includes an eyesight test as part of the medical examination after final selection.
The required vision standard depends on the medical category of the post — A-1, A-2, A-3, B-1, B-2 or C categories, with A-1 being the strictest.
For higher categories, glasses may not be allowed and colour vision is tested with the Ishihara chart.
Failing the prescribed vision standard for your post’s category leads to medical unfitness for that post.
Always check the medical category mentioned in the official notification before applying.
