What is success?  It is you actually looking at  your own Snellen - and accepting that passing the
20/30 line, is a good success - so you can "dump" that minus lens.

The hard part - is being able to understand that long-term plus wearing is required.

Are you tough enough - to do it  yourself?

Hint:  Do not ask an OD for help - do it yourself.
