What type of lens is an executive lens categorized as?

An executive lens is categorized as a one-piece lens because it is designed as a single, continuous piece of material that incorporates both distance and near vision correction within the same lens. The distinguishing feature of an executive lens is its large, flat segment for near vision, which is often located at the bottom of the lens and provides a wide visual field for tasks requiring close-up focus. This design maximizes the reading area while maintaining the distance vision area above it, creating a smooth transition without the visible line found in traditional bifocal lenses. This integration of different vision zones into one seamless lens enhances functionality and aesthetics, making it easier for the wearer to switch between different focal points without disruption.
