[Tig] eyesight- lenses

[Rob Lingelbach]

when you turn 50 or even sooner, you find that (in my experience  
anyway) your glasses don't give you the fine detail
at differing distances that younger colorists have.   Can anyone tell  
me about constant gradient (not bifocals) lenses?
do they help, are they worth it, is there a reason to use them?

I have no problem with monitors at 40" or so from my eyes.   all  
details sharp and can discern things that even my 20 yr
old assts. can't see.  but when I'm on a computer where the distance  
is 20", I've got a problem, which is that either I move
the glasses out of the way and lean in to see the text, or I use the  
glasses but the text is so small I can't read it.

my prescrip: -1.50 left -1.75 right diopter

They tried (lensmasters in LA) to sell me constant gradient lenses  
last time I was there but I was quite resistant to change.
(constant gradient: as you look down, magnification increases (I  
believe) and as you look up, things are back to your usual
prescription).
