    My sister has been complaining about her distant vision for sometime and has gone for a few eyetests but as far as I can tell the Optometrists have been telling her she does not need glasses for distance just reading. She is after getting her prescription from an optometrist as follows:

    R+0.75/-0.25x70 L+1.00/-0.25x80 Add +1.75

    Does this mean she just needs reading glasses +1.75?

    Thanks.

    I understand the Add 1.75 part to be the reading addition. If she had glasses made using the prescription without the reading addition what type of vision correction would they give? Thanks
