The bottom/progressive part of our glasses are the magnified reading glasses portion which is typically required as most folks age. ..
Agreed (to a point), point being though that your suggestion that I am focusing on the mirror and not looking 'through' it falls flat because I would otherwise be unable to use mirrors in general. Also the inability to use helmet mirrors was a gradual deterioration of picture quality not a sudden inability to redirect my focus such as in no longer being able to see the hidden image in Magic Eye pictures. Maybe it has something to do with astigmatism and such a small target as a helmet mirror, I don't know but the fact is that as much as I'd like to be able to use helmet mirrors again, not to mention save money and no longer be inconvenienced by having to adjust to different mirror locations depending on which of my bikes I decide to ride, they just aren't an option... at least not the ones I've tried every now and again in more recent years.
