Thanks for the response, I really appreciate it.
Because I have bifocals and my script is quite high, everything pretty much needs to be custom unfortunately.
I do have a need in my life for a spare pair of sunglasses and apparently they can be used as a backup so this might be an option. I also considered transition lenses, but just called AvMed to ask about whether they are allowed or not and the rep said they weren't. However I've seen other topics where pilots have been discussing using them!

You can read the DAME handbook on the CASA w3 site which will have the vision standards.
