    Hi,
    I have had prescription lens since Jan and was wondering what the numbers stand for.
    The OD Sph is 075
    The OS Sph is 025
    I see other ppl talk of -2 to +5 etc etc.But what do they mean in relation to mine.
    I appreciate the help.
    Thanx

    A prescription written down without a sign such as - or + almost means it is
    meant as + power (plus)
    Please give more details of what is written down on your prescription, I
    hardly can believe those notations where the only ones.
    That is, if you want more information.

    Dear Sir,

    OD, means "right eye"
    OS, means "left eye"

    Sph: Means spherical (i.e., no astigmatism cut into the lens)

    075 means 0.75 diopters (you need to tell us plus or minus)

    025 means 0.25 diopters (you need to tell us plus or minus)

    Best,
