your head.wmts
Quoting Dick J <lsr_man@yahoo.com>:
> Jon, any GOOD optician should be able to fix you
> up with proper glasses. I have a pair that my
> optitian calls Occupational lenses. He had me
> measure distances from the corner of my eye to
> everything I use at work, then he used two of my
> three prescriptions (usually trifocals) and made
> special occupational lenses that have focal
> lengths for arms length work and 24 feet (the
> distance to the door in my office). Lenses could
> easilty be made with one prescription set for the
> instruments, and the other for driving distance
> (infinity?).
>
> My second pair have my regular trifocal lenses.
> For driving, I have special sunglasses with the
> driving linse in the top half and the lower half
> set to read the dashboard. I even had the
> no-line transition set at a height that let's me
> rest my head on the headrest and still be looking
> through the distance prescription.
