Not a photo, but a question

I read 10 Reasons to Turn Off Your Autofocus from Digital Photography School this morning. I agree with the points, and have had some of the missed shots the article warns against because I have used autofocus.

BUT.

I have crappy vision. Even with contacts, I don't see 20/20, and the viewfinder of my camera is very small. I love photos -- portraits, especially -- with super shallow depth of field, where the eyes are sharp as a tack and everything else dissolves into buttery lovliness. I've got a great lens for it, my 85mm f/1.8. But how can I be sure I'm manually focusing well enough when my own eyes don't know how to focus?

Is there a solution? Or do I just need to suck it up and count on some of my AF shots and many/most of my manually focused shots to fail?

Hmmmm.
