Fitting
Single vision lens
To maximise the visual benefits of an aspheric lens, a vertical fitting height must be specified. The optical centre of the lens should be placed 1mm below the centre of the pupil for every 2° of pantoscopic tilt of the frame. For example, of the pantoscoptic tilt is 10°, the height specified should be 5mm below the pupil centre.
Progressive lens
As per design specifications. (All Essilor and Nikon progressive lenses should be fitted on pupil centre).
