I am near (short) sighted. My last eye test was five years ago in 2011. I've just had another eye test today (at the same Opticians), and they said I needed new lenses. I then chose new frames, and they'll be ready to pick up next week. In the meantime, I'm wondering how my prescription has...

    First , we have to convert the first one to the same format as the new one, from + cyl to - cyl

    The old one becomes - 2.00 - 0.50 x 90

    The only real change is that your astigmatism correction has increased to - 1.00 and - 1.25 from - 0.50

    The minor changes in the sphere power and the axis is negligible.

    It will probably take a few days to get used to that change, but it should make colors brighter and everything should be sharper.
