    My optician is recommending that I replace my varilux
    comfort lenses with Definity lenses. He says I will get
    more periperal acuity. I could use any help I can get as my
    maximum correction leaves me close to 20/40. I have very
    bad astigmatism.

    How would Definity work for computer/workstations glasses as
    well?

    TIA

    The link below is for the definity web site.

    http://ecp.definity.com/main.htm

    The site makes the following claims:

    a.. DEFINITYT Lenses provide patients with the widest intermediate zone and
    least amount of peripheral distortion of any progressive lens.
    a.. DEFINITYT Lenses provide a much wider intermediate zone than
    Conventional Progressive lenses.
    b.. DEFINITYT Lenses have significantly less peripheral distortion than
    Conventional Progressive lenses.
    Unfortunately, it doesn't define "conventional progressive lenses". How do
    these compare to Hoya, Zeiss,etc?

    This is an old thread that I now just saw and my reply is probably too
    late to be of use to you. I investigated the various progressives 2
    years ago and settled on the Definity. I work extensively at the
    computer and the Definity has a very broad intermediate zone that makes
    computer work comfortable. (I previsiouly had Essilor Naturals which
    were not as comfortable for computer work.) I am also fairly amazed at
    the width of the channel of sharp vision. I often don't even realize
    that I am wearing progrssives. I highly recommend the Definity, though
    they must be fitted very, very carefully. The first pair had to be sent
    back because they were miscentered. Unfortunately, Definity has been
    sole by Johnson and Johnson and I believe purchased by Essilor. The J&J
    Definity lenses were only ground in their shop in, I believe, Virginia.
    I don't know if Essilor still manufacturues the lenses in that
    specialized facility or not. If they have farmed out the grinding to
    local labs that grind the other Essilor lenses, I would be skeptical
    that they are still as skillfully made, but hopefully I am wrong on that
    concern.
