• TESTING THE PARELLISM USING FLAT
SURFACE

6. (1)POWER : we are checking
spherical and cylinder power…
• Power is checking by patient
prescription card.
(2)AXIS : We are checking axis of
cylinder power.
(3)CENTRATION : We are checking

orientation if we are prescribing….

8. TESTING PARELLISM USING FLAT
SURFACE

9. RIMLESS FRAME ALIGNMENT
