    OK, I trust you.

    As a general rule (almost an absolute law of the known universe) one always rounds down for astigmatic correction.

    Because it sure seems to melt when heat is applied.

    I crazed the daylights out of a lens (AR-coated) by heating the bridge (and I used that "concentrator" thing on my hot air blower). That's an...

    I hate Costco because they're a cult. I have patients that are members of Cultco, and they take their contact and glasses Rxs to their Temple to fill.

    Back-side (internal) segmented multifocal

    A patient wants a segmented BF for a pair of wrap sunglasses, but wants a mirror coating.

    Zeiss is extremely well-respected for their quality, but the company tends to be overly-expensive and difficult to interact with.
