Right on! To say nothing of the dramatic effect the glasses can have,
in some cases, for helping you "free view" parallel. Although I could
do crossed eyes free viewing easily, I struggled for YEARS in my early
adulthood trying to master parallel free viewing, and could do it only
after GREAT effort, even with reduced size images that were only 2"
apart, and then would be so strained out I couldn't repeat the success.
But when my farsightedness became a nuisance, I got my first reading
glasses. When I put them on, I was able to parallel free view almost
instantly, with no strain! With a little practice, I found I could even
free view stereo cards, which have a wider separation than most people's
eyes, including mine (some people think my eyes are so close together
they overlap...).
So get those glasses and enjoy!
Cordially,
Oliver Dean
