What Percentage Of Rx Work Falls In The Range Of My Q-2100?

When Optical Dynamics determined the power range of the Q-2100 Digital Lens system, they studied over a million prescriptions dispensed in the US.

The +4.00 to -6.00 range with cylinders out to a -2.50, and add powers from +1.00 to +3.00, cover approximately 93% of the total Rx range studied.
