摘要:
Progressive lenses designs are disclosed having optical parameters such as the width of a far vision zone, the width of a near vision zone, the width of a corridor, the maximum residual cylinder, the maximum gradient of residual cylinder, that vary with addition. Such lens designs may provide improved performance for individuals requiring different amounts of addition (such as individuals having different ages) who spend more time performing different types of activities such as viewing hand-held devices like smart phones and tablets or reading books.
