MPORTANT NOTES
> The maximum distance between the apex of the bevel and the front face is 5 mm.
>
The finishing position can be modified in four points: top, bottom, temporal, nasal. Only the bevel apex is
displaced along this point. The opposite side remains fixed and the curve of the bevel is unchanged.
>
If you wish to reposition the whole bevel, move the bevel apex in one direction to the required position. Then
do the same from the opposite point.

IMITS
> If the maximum thickness of the lens is less than 2 mm, the applied bevel will automatically be of 50% type,
whichever type of bevel is selected initially.
> To make a safety-bevel of any type, the minimum distance between the bevel apex and the front/rear face
must be greater than 1.6 mm. If it is less than 1.6 mm at any point of the lens, the safety-bevel will not be
produced at this point.
