I had mono vision for years, but lately my eyes started to "bounce around" when I would try to focus on something. So for the last visit I had my DR. give me the same in both eyes. I can see far to read signs when driving (and further and closer, don't worry) and can see computer and paper print to read but if it is really small print I need cheaters. If I sew either by hand or machine I don't wear any glasses or contacts. Guess my field of vision changed as I got older.
