    I'm wondering what sort of differences I would see between -5.00 and
    -5.25 power for contact lenses?

    I'm asking because I am currently wearing -5.25 and just had an eye exam
    and was prescribed -5.00 instead. I am wondering if there is much
    difference between the two and what I differences I might expect with
    the -5.00 contacts?

    The difference is 0.25/5.25 less power...or slightly less than a 5%
    decrease. If you could see as well with a prescription that is 5%
    less, would you?

    sure, i suppose i would. but i'm worried that i'm used to the -5.25 ones
    and when i get the -5.00 ones in it may look worse? is this crazy to
    think this?

    he did mention that the -5.00 would be better for comfort in computer
    work and reading. but how will it affect far distances?

    If they are disposable, you could ask for a trial lens.

    I assume that most eye doctors do as I do, which is to give their
    patients the best possible distance vision, without over-correction.

    Well go find out!

    Why don't you simply stop by the doc's office with your -5.25 lenses in
    and ask to view the world through a +.25 hand-held lens ? You will see
    instantly the effect, or lack thereof. No change, then clearly (pun
    intended) you will do better with the -5.00. Blurry, then better to
    stick with the -5.25.

    If it IS blurry, then it's a personal preference issue if the distance
    loss of acuity is worth the possible (if you're over 45 or so)
    improvement at near.

    If you actually need -5.00 lenses to see 20/20 in the distance, but have
    become used to -5.25, then you might initially experience a little distance
    blur with the new lower -5.00 prescription. This will pass within a few
    days as your eyes readjust to the proper prescription.

    Celebrate you new lower prescription! Your eyes have gotten better and you
    have personally disproven Otis' theory of "the wretched minus" (inside
    joke-- just forget it).

    Either that or the original -5.25 was mis prescribed for me a few years
    ago when I got it.


    Follow up:

    I got the -5.00 contacts in and also still have my old -5.25 contacts on
    hand.

    I can tell zero difference between the two, they are both quite crisp
    and clear both for closeup and far.

    So I guess this means that the -5.00 is the best one to use since it's
    less correction?

    Is it strange that I can see equally as well with both?

    Are the -5.25 contacts physically thicker than the -5.00 ones?

    I'm asking because the -5.25 soft toric contacts I have seem to not move
    around on my eye when I blink as much as the -5.00 ones.

  9. Not noticeably. Any difference such as you have noticed are not due to
    just power difference, unless the manufacturer has screwed up. More
    likely, you screwed up, your doctor screwed up, or someone in between
    screwed up...
