    Maybe the physical aspects are unlovely, but the optics are

    with no prism).

    Thanks for the info on the 14 mm sep CRT tri, I might just
    try out a pair.

    IMO all progressives look nice but are rotten optically
    whenever viewing a comp. monitor or an serious close work.

    My personal computer glasses are exec bi with +.75 over my
    refractive error in the distance and a 1 add, which now
    needs to go to 1.25. Sigh.

    I'm using a set of 14x35mm trifocals at the moment. I keep then in a
    case velcroed to the side of the monitor. I've yet to meet a
    progressive I truly like to look through for computer use. I guess I'm
    just too picky for my own good. LOL I'm somewhat happy with the
    Percepta for general wear.

    Hello Carl,

    I'm looking for a trifocal with a larger depth for the intermediate correction. It looks like you found a pair that are 14mm. I'd be greatly interested to know where you got them.

    Thanks,
    Steve
