CVf is a custom-made single vision lens with a double-sided  aspherical design. It provides a clear natural view with less  distortions. This specific design reduces the thickness of positive  lenses, compensates for the difference in thickness when the eyes have very different prescriptions and adapts to the frame’s wrap angle.

The optimization of the design allows to obtain thinner positive lenses and eliminate the imperfections related to the eye enlargement effect. You can choose between standard base, base 3 or base 5, that best suits the angle of wrap so that the lens fits perfectly to the frame.

When the right lens and the left lens have very different powers, it ensures that the thicknesses and weight are automatically balanced to make the two lenses similar and aesthetically better.
