You are suffering from 'long arm' disease- that is where you need longer arms to get the restaurant menu farther and farther away or you cannot read it. One day your arms just are not long enough anymore.
As we age, the lens in our eyes thickens and hardens (easy boys!). The muscles that stretch that lens cannot get it as thin as they could when were young and our lenses pliable. So the short focus, which is when a thin lens is required, gets more and more out of focus. Watch little kids- they can look at stuff almost touching their noses.
There is no fix other than additional lenses (glasses, contact lenses, welding mask inserts, whatever) or a new lens. When you are old enough to have to have the cataracts removed, have the doctor put in a 'close' lens in one eye and marvel at how much better you can focus on things close to your eyes.
A welding insert may work in your helmet visor, fastened to the bottom. You would have to cut one up but they are inexpensive enough. Other than that or eyeglasses, there is no way out of it that I know of.
I am currently using a Zumo 550 and walking the fine line between 'it is too far away to see' and 'it is too close to focus'. And yes, I am wearing a pair of cheap drug store glasses as I type this. From what I hear, it don't get better as we get older either.... :-(

I'm not old but pushing 50 and I don't think I'm alone when I confess that I can't see the damn screen on anything less than a 7 inch GPS. Now I haven't mounted a GPS on my bike yet but I can't imagine being able to use anything but my 7 inch.
I can't be alone. My eyes are 20/15 but I cant see close up for crap. I dont need glasses to drive and i just use cheap dollar store throw aways for reading ....and typing this.
C'mon guys what's the secret ?? How do you read your GPS ? Bifocals ??
And,,,do you think I can fit a 7 inch GPS between the bars ?
