What happens if they find a problem? Like, your vision isn't quite up to scratch? Is it a straight fail, thanks very much, no job for you or more get yourself a pair of specs n come back next week? Surely folks must have problems they're not aware of as they've just not noticed them.
If a problem is discovered, which may be treatable, you would normally be referred to your GP or Optician (for eye issues).
In my case, I had issues with my blood pressure as I suffer with white-coat hypertension. I was sent to my GP, who confirmed that’s all it was. She wrote me a letter to send in. Two days after sending the letter to Occupational Health, I passed my Medical. (This all happened within a week)
I imagine if you can get your vision sorted out at your opticians within a reasonable timeframe, then you will pass your medical.
Also, your TOC would typically request you visit your optician before your medical anyway, so you can provide a vision prescription certificate. Any vision issues you may have should be flagged up there, and can hopefully be resolved prior to your medical.
You must meet the required medical standards before you can begin training, but definitely try not to worry too much about your medical. They will do all they can to get you through.
