Unfortunately any corrected vision is immediate disqualification for aircrew i.e glasses/contacts. If you google avr1, aviation visual requirements 1, the eye sight requirements for aircrew, it should outline cut off parameters. I would recommend seeing a few ophthalmologists and consulting their advice whether you can make these standards. Certain types of laser surgery is allowed, but consult an ophthalmologist for that. I'm currently in the same boat, being held back on enlistment due to an eyesight issue discovered in my post flight screening medical. For your medical on the assessment day they might determine you medically unfit prior to flight screening.
Feel free to send me a pm if you want any further advice.
Cheers, Alec
