    I was told by VSP rep that the VisionWerks has its own lab capacity.

    I think the stress is from forced layoffs.

    In a plano prism lens, p.d. and height is irrelevant. You could tell the lab anything and it will come out the same.

    Why?

    Because: p.d. and vertical height is the desired X-Y location of the...

    Do OTCs even come under ANSI? I'm guessing "no".

    I doubt they're even considered "spectacles".

    Nope.

    Acuity is acuity.

    You can't fudge it. It doesn't increase or decrease (without some tangible reason). It doesn't vary. Look it up.

    Yeah, but how much are we talking?

    One gram = one paperclip. Balance a paperclip on the front of your glasses and tell me how your nose hurts.
