Assuming you otherwise meet the sight requirements, partial vision in one eye (or even loss of one eye completely) won't prevent people getting a UK driving licence, though they need to consult an optician and inform the authorities of the situation:

Given this, you can presumably get a UK license in the same way as anyone else resident in the UK who doesn't have one & doesn't have an overseas license:

I would recommend that you first go and speak to a UK optician who will be able to verify whether you meet the eyesight requirements (they're used to checking this).
