    Hi..
    Just find out about this goggle group.
    I am in my early 40's and starting to try contact lens.
    My nearsighedness is not too severe (-2.75 - sphere, both eyes) but I
    have astigmatism. I believe it is -1.75 (OD), and -1.25 (OS)... Can
    someone enlighten me about the meaning of "OD" and "OS"? I think they
    are related to "left" and "right" eyes??

    I have tried my 1st pair of contact lens and it seems to be
    unacceptable at work (indoors) - particularly hard to read
    documents/texts and computer screen. I also find my vision clearer
    outdoors (sunny for the entire week).. I see my optometrist today for a
    2nd time and he has given me a 2nd pair of contacts to try out.

    Frankly, I have been trying out the entire afternoon... so far..
    similar results - outdoors vision seems to be much better. but when
    indoors (shopping mall, or home), then it's much harder to read text or
    computer screen (unfocused images of text).

    My questions are:
    - is my experience unusual? or it's common to try out a few pair of
    lens to find the right one?
    - how many trials is considered "normal" during the fitting process?

    I will return to see my optometrist a week later and see how things go.
    I am just feeling antsy about the outcome....

    Would be great to hear about others' experience.

    Thanks for sharing.

    ps: The lens that I am trying are ProClear toric.

    Has your eyecare practitioner tested you for presbyopia (loss of
    close-up vision, which naturally begins in one's 40s)? When I hit 40, I
    could barely read with my distance contacts in (or glasses on).

    I tried 4 different types of contacts before I settled with Acuvue 2.
    I wear one for distance and 1 for close-up. This system is called
    monovision, and it works well for me.

    Myopic people at your age and changing from glasses, like your
    prescription, to contactlenses don't have the comfort of the

    Normally this should be told before you are fitted.


    I also find my vision clearer
    Has to do with the pupildiameter, the smaller the diameter the more
    depth of (sharp)field (like in photography with aperture)
    Outside the light intensity is higher and therefore the pupil has a
    smaller diameter.
    The same insides when you switch on the lamp.
    No

    Depends on the skills of your fitter.
    Depends on the difficulty of your prescription and what you want to be
    fixed.

    An excellent lens.
