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.
