| 摘要 |
An optical zone for a lens has a center optical axis. A first region of the optical zone includes a first optical curve having a first optical axis that is collinear with the center optical axis. A plurality of secondary regions is formed within the first region. Each of the secondary regions has a respective secondary optical curve with a corresponding secondary optical axis. Each secondary optical axis is collinear with the first optical axis. Each of the secondary optical curves is decentered relative to the first optical curve.
