C
URVE ANGLE AND FRAME BASE
1. Curve angle: relative parameter formed between the median plane of each frame rim and the general
plane of the frame. It is used to compute the decentration necessary for curved corrective lenses. The
curve angle is expressed in degrees.
2. Frame base: parameter corresponding to the radius of the sphere going through the maximum
number of points traced on the circle. It allows a better correspondence between lens bases (bevel)
and the frame. Frame base is expressed in dioptres.
E
