SIMPLE TRANSPOSITION made easy!

This complete tutorial talks in detail about simple transposition .The simple transposition is a process of conversion of a lens prescription from one form to another optically equivalent form. The video explains the 3 easy to transpose .
Step 1 : algebriac sum of the sphere and the cylinder
Step 2 : changing the sign of the cylinder
Step 3 : changing the axis of the cylinder through 90 degrees.
this video explains transposition using three examples .

[@tomcruise9317]

Mam then why it is done if they tell same meaning

[@InsightOphthalmology]

One prescription might be more comfortable to the patient than the other( although both mean the same) ; hence we can utilise transposition there
