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 pantoscopic tilt is 10°, the height specified should be 5mm below pupil centre
Progressive lens
As per design specifications. (All Essilor and Nikon progressive lenses should be fitted on pupil centre)
Note:
Do not use solvents such as acetone or ammonia to clean Airwear lenses
They may attack the material via the unprotected edge where the hard coat has been cut away during edging. Progressive markings are easily removed with non-acetone nail polish remover (readily available in supermarkets or pharmacies). Eucalyptus or tea tree oil may also be used.
