The optical cross is the graphical representation of the two primary or principal powers on a lens. Toric transposition is the graphical representation of the powers (or curves) on the front surface of the lens and the back surface of the lens. DL = D1 + D2 or FL = F1 + F2. For optician training or ABO NOCE study, this lesson is based on an exercise sheet that a member asked for help reviewing. The lesson covers the concept of toric transposition and then goes on to work nine individual step-by-step problems.
