Vari-Focal
Vari-Focal are used for correcting vision for people who require two different prescriptions, for distance and close up. Vari-Focals work in the same way as Bi-Focals, but unlike Bi-Focals they have no visible dividing line between the different corrections. How this works is the one prescription progresses smoothly into the other prescription. This allows the wearer to see clearly whatever the distance. The great advantage with vari-focal lenses, is that they look like a single vision lens.
There are various different types of Vari-Focal lenses available.
Please see your optician for futher advice to which vari-focal best suites for requirements.
