P3D Eyeglasses and viewers

["John Goodman" <jgood@xxxxxxxx>]

I recently got fitted with some glasses for the first time, to 
correct moderate astigmatism and 48-year-old eyes. One 
of the pairs is for medium close-up, such as would be 
useful for computer work, optimised for about 23 inches.

Using these medium glasses with stereo viewers is a 
revelation, profoundly better than my uncorrected sight. I 
don't know if this is a lucky coincidence or par for the 
course. I'm seeing details I didn't know were even 
possible, right down to what looks like the slides' "grain". 
This may be old hat to experienced eyeglass wearers, but 
if any of you are avoiding getting glasses for the first time, 
I think you may have a lot of pleasure to look forward to.
