Abstract: Various embodiments disclose a quasi progressive lens including a first optical zone capable of providing distance vision, a second optical zone capable of providing near vision and a transition zone connecting the first and second optical zones. Physical dimensions (e.g., length and width) of the transition zone are adjusted to increase the size of the second optical zone in comparison to progressive lenses and to reduce residual cylinder power and aberrations along the convergence path in comparison to bifocal lenses.

Abstract: 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.
