When light passes from one transparent medium to another, it bends according to Snell’s law which states: that the angle of refraction is related to the

The optical properties of the prescription remain the same.

Procedure: 1) Add the cylinder power to the sphere power to arrive at the new sphere power.

2) Change the sign of the cylinder power.

3) Add or subtract
