    Default questions about multifocal lenses,

    when fitting multifocal lenses, how is the height of the reading area determined. the last set of online glasses l purchased l found that the reading area was too low.
    Thank you.

    Normally, the division is 70% of the lens height for distance and 30% of the lens height for reading.
