    I am about to order new lenses, and would like to get the "best all around"
    lenses that do not cost too much. I am -2.25 / -2.25. I wear my lenses 12-14
    hrs/day, lots of computer work.

    At this point, I am considering Coopervision Frequency 55 and Ciba Focus
    Monthly lenses.

    a) Is either one a better lens and why? (the F55s are cheaper)

    b) I have a trial pair of the F55s with Base Curve shown as "MED" and seem
    to fit fine, but order forms show 8.4, 8.7, or 9.0 available... Q: which is
    equivalent to the MED curve? 8.7?

    c) Any other lenses that I should consider?

    Thanks in advance!

    there are literally hundreds of lenses like the ones you are
    considering. if they feel comfortable to you, and you see well with
    them, and the eye doc says they fit you, then they will work fine for
    you in the way you intend to wear them.

    typically these brands of lenses are not the least expensive brands, at
    least where i live (midwest US). there are very similar lenses that
    are more aggressively priced by the manufacturer. i would try lenses
    made by biomedics (e.g. biomedics 55) and vistakon (acuvue 2).

    you are right. MED = base curve 8.7

    As others have said, while it is true that the silicone hydrogel lenses
    are superior to the older HEMA based lenses that you are trying, they
    should still work fine for you since you don't plan to wear them for
    excessive periods of time and they are comfortable to you. they are
    also less expensive which seems to be a concern for you.

    If you want the healthiest lens for your eye at the best price for
    those lenses, then I agree that 02 Optix or Acuvue Advance is the best

    thanks but...

    I just tried some CIBA O2 Optix for 3 days and was disappointed:
    - made my eyes sting and go bloodshot
    - vision was somewhat blurry, noticeably worse than w. Freq. 55s
    - expensive
    - PS: I use ClearCare sol'n, which I have been for a year w. no problems

    what about Coopervision Biocompatibles? (vs. silicone hydrogels).. I used
    these for 3 years no problems, but was hoping to switch to cheaper lenses
    (they are priced same as the expensive vs. silicone hydrogels)

    NOTE: Coopervision Biocompatibles a.k.a. ProClear

    the aspheric design of 02 Optixs also causes blur for many patients.
    some docs deliberately overminus patients a little to reduce this

    Biocompatible is a good lens. You should try Biomedics XC which is
    very similar and less expensive. I have had lots of patients who are
    very satisfied with these lenses and pick them over silicone hydrogels
    in side-by-side comparisons.

    seems the Biomedics XC are described as a 2 week lens on the Coopervision
    site... I understand Proclear/Biocompatibles are 1 month.... so, does that
    mean I will go through the XCs twice as fast? ao, are they both OK for 1

    seems that Coopervison makes both, but the XCs are definitely cheaper

    Just wanted to comment on this--I wear the Extreme H20 lenses, and they
    work well for me (I have dry eye), but I noticed from the beginning
    that I needed more minus power in this brand--to achieve the same
    acuity as in other brands. Has anyone else noticed this?

    I wonder if people just trying these lenses for the first time would
    find them "weak" and vision blurry as I did, and give up on them for
    that reason.

    The correct lens power for any given brand/design/fit is determined
    while the lens in on the eye. It is not unusual for someone to need + or
    - .25 or so difference from one brand to another. The only way to get
    "weak" blurry vision is if the lens is incorrectly fitted and
    prescribed, like basing it on a spectacle correction and not checking
    the visual acuity and adjusting it appropriately.
