I did some research on this and different countries have different regulations. For UK -6.0 is borderline unacceptable, but for ICAO standards including countries such as Australia, USA, some Asian and Middle Eastern countries it is acceptable as long as your vision is correctable to 20/20.
As far as I know, the CAA in the UK see it case by case, so you may still be accepted for Class 1. The only way to find out would be to go and get assessed I suppose.
