Answers to couple of questions. Picked up a few answers from the web.
Vision : you can join any department except GDP if the vision is week. If you are selected in the GDP and your vision goes bad you fly with glasses.
There are four areas of vision that are tested for Fighter Pilots. You must pass each of these to qualify for a flight slot; however, you do not need 20/20 vision to pass.
1. Distant Vision
2. Near Vision
3. Color Vision
4. Depth Perception
If your vision is bad and you are concerned that your vision does not meet the standards then there are a few things that you can do to improve or maintain your eyesight. Here are some exercises that you can do to help keep your eyes at their strongest.
Close your eyes tightly for 3-5 seconds, and then open wide for the same amount of time. Repeat this 7-8 times.
Roll your eyes clockwise, and then counter-clockwise one full rotation. Repeat 5 times.
Hold an object such as a pen out in front of you at arms length and slowly move it close to your nose while focusing on it the entire time. Repeat this 5-10 times.

Selection: No the section is not hard at all academically but yes the selection process is very competitive 1 seat per 3000 candidates.
Overseas Candidates : Instead asking a question on the net I would suggest call the selection center early in the morning doesn't matter which one or which city. Tell them that you are calling from outside Pakistan and need to speak to the Officer commanding of the Selection Center and ask him all the questions. why I am saying this policies and procedures keep changing so its better to hear it from the horses mouth.
