Alvarez Lens Technology
The “Alvarez Lens” is composed of two moveable parts with a flat surface facing each other and a “Saddle Form” on the outer surfaces, see images below. The refractive power of the combined lenses varies proportionately with he amount of relative overlap of the two parts and the resultant lens thickness.

The two lenses are mounted within a frame spectacle assembly using a flexible screw (Dial /
Adjuster). The screw also acts as the adjustment mechanism for the product, to vary the relative position of the two lenses. The left and right lenses can be adjusted independently to take account of variation in the user’s eyesight.
