Pupilheight is the abbreviation of pupil center height, which refers to the distance from the point where the visual axis of the eye passes through the lens to the lowest point at the bottom of the groove at the lower edge of the frame.

Pupil height can be divided into far pupil height and near pupil height. When there is no special requirement, the pupil height of hyperopia glasses is generally a little on the horizontal line of the geometric center of the frame. The pupil height of myopia glasses is slightly lower than the horizontal line of the geometric center of the frame. However, there are strict requirements for pupil height when preparing progressive multifocal glasses. Generally, the pupil height is taken according to the golden section of the distance between the upper and lower frames.
