Peroxide cleaners - Do not shake?

Discussion in 'Optometry Archives' started by Lothar of the Hill People, Aug 31, 2003.

  1. I have heard a couple of people on this newsgroup (or maybe it was the
    same person twice) recommend shaking their contact lens cleaning case
    about an hour before putting the lenses in their eyes, to make sure
    that all the hydrogen peroxide in the case has come into contact with
    the neutralizer. This sounded like good advice to me, both for
    neutralizing purposes, and perhaps also to dislodge any remaining
    deposits that might be sticking to the lenses. However, the
    directions on my peroxide solution (AOSEPT Clear Care) say, in bold
    letters, "DO NOT SHAKE THE CASE." Can anybody tell me why it should
    not be shaken? If I had to guess, I would say that perhaps it
    releases too much oxygen too quickly and would make it bubble over, or
    perhaps that it neutralizes the solution too quickly, before the
    lenses are fully disinfected.
