Sample text

Thus r H will be infinite as the cylinder is plane parallel to the axis. A section perpendicular to the axis will have (J = 90°, sin fJ = 1, and r H = r as you would expect. A useful application of this result is to demonstrate that any spherical surface can be replaced by two identical plane cylinders, with axes mutually perpendicular. 6, two cylinders with axes 90 and 180 have the same curvature R. A generalized axis e is taken, along which the curvature is RfJ. Since If the thickness of a cylindrical or spherocylindrical lens is required along or perpendicular to the axis of symmetry, then the problem is similar to the spherical lens situation, except that there are two meridians to deal with.

The traditional nomenclature for a toric lens is: Example: • Sphere curve: power of the spherical surface • Base curve: lowest absolute power (longest radius) on the toroidal surface • Cross curve: highest absolute power (shortest radius) on the toroidal surface. 00 DC toroidal base curve The terms 'base curve' and 'cross curve' originate from the traditional method of manufacturing front surface toric glass single vision lenses. The term 'base curve' is now more likely to be used to describe the front spherical curve of a semi-finished lens which is designed to have a toroidal surface subsequently placed on the back.

4 ern = 4 mm Out Note that although Prentice's Rule states decentration in ern, it is usual to quote answers in mm. If the focal power is low or the prismatic power required is high, then too much decentration may be required to provide the prism in this way. 50 OS lens? 5) = +8 em =80 mm Out The maximum possible blank size of most modern lenses is about 80 mm, and so obviously 80 mm of decentration cannot be incorporated into a lens. In cases such as these, prism must be worked onto the lens using the Workshop Prism Formula .
