[ p = f1 + f2 + (f1 times f2 times d) ] where: Discover how to use a crossed cylinder calculator to determine the power of crossed cylinder lenses in optometry. Using the cross cylinder calculator can be a breeze when you follow these simple steps:
Lens 1 Has Smallest Cylinder Axis.
It examines the pressure distribution and contact forces between two cylinders that cross each other at an angle. A crossed cylinder lens combines two cylindrical lenses with perpendicular orientations to correct astigmatism and other refractive errors like myopia or hyperopia. ( p ) is the power of the crossed cylinder lens (diopters).
