eye exam numbers between and optometrist versus opthamologist?

I have a question about eye exam numbers? Supposedly I see 20/20 with my glasses but the number the opthamologist gave me is so different on the new perscription than from my last exam from an optometrist. Can you tell me if they are relatively the same? He said they are.and mentioned that I would not even need to get new glasses but because they are scratched now, I would like to, but I am concerned whether to buy a new pair because of the cost, or if I should go elsewhere and be rechecked. I am blind as a bat, but I am concerned and have not placed an order yet because I am worried about these new numbers. Thank you!

At present i am wearing this number

RIGHT EYE:

------------------

SPH -6.00

CYL -1.25

AXIS 3 degree

LEFT EYE

----------------

SPH -7.50

CYL -2.25

AXIS 165 degree

I went for my eye check-up today and doctor gave me following number

===========

RIGHT EYE

------------------

SPH -7.50

CYL +1.75

AXIS 90

LEFT EYE

-----------------

SPH -10.00

CYL +2.50

AXIS 77

    The second one, from the ophthalmologist is in the + cyl form , it has to be converted to a - cyl to really see the difference.

    The right eye becomes - 5.75 - 1.75 X 180

    The left eye becomes - -7.50 - 2.50 X 167

    Now we can see that they are almost the same thing. Just a little 0.25 change here and there, and a 0.50 change on the right cyl.

    Axis 180 & 3 are only 3 degrees apart , even though it looks like a lot.

    It looks very normal , and they are virtually the same from both places.

    Actually they aren't that far apart. The 2nd number or cylinder is written in (-) on one and (+) on the other. When you transpose the prescription on the newest one it would read:

    R -5.75 -1.75 x 180

    RIGHT EYE:

    ------------------

    SPH -6.00

    CYL -1.25

    AXIS 3 degree

    L -7.50 -2.50 x 167

    LEFT EYE

    ----------------

    SPH -7.50

    CYL -2.25

    AXIS 165 degree

    The new Rx should sharpen things up a bit, and the old ones will make a great spare pair being very similar. You had a slight decease in your nearsighted correction and a small change in the astigmatism correction both eyes.

    um yeah that's a pretty big difference you can get new ones made with the new rx and if you can't see out of them make an appt with the doctor again usually there is not a charge for a reck of your rx. I would get them made at a place where you know if the doctor messed up your rx they would replace your lenses for free after getting them recked
