    I had a question about something suspicious I noticed in my glasses prescription reports from my past 2 optometry visits. The first was in October 2009, the second was this past March 2012. I have been having some trouble seeing out of my left eye (with glasses from the 2009 prescription) of late, but my optometrist said that the change doesn't warrant new glasses. But, now as I examine the printouts he gave me after each of these visits, the numbers after the "x" are completely different between the two visits. In 2009, it was "010" for OD and "180" for OS. In March 2012, it was "180" for OD and "03" for OS. Which to me appears more or less completely swapped. But I am a layman and have no clue how to interpret these numbers (which is why I was just trusting my optometrist).

    I've typed the exact parameters from the 2 reports below. (I've triple-checked to make sure there are no typos, so if there appears to be a typo here, it's on the part of whoever typed up the report at my clinic.)

    2009:
    OD: -2.00 +0.75 x 010
    OS: -3.25 +1.50 x 180
    ADD: +3.00 OU

    2012:
    OD: -1.75 +0.75 x 180 20/20-2
    OS: -3.25 +1.75 x 03 20/50-2

    Assuming these numbers are correct, would this represent a significant change between 2009 and 2012, warranting new glasses?

    Thanks in advance,
    Stanley

    Go for test is the first thing that you have to do for obtaining prescription. Basically after two-three prescription get expired and if the period is already gone then you should definitely go for testing in the eyewear.
