Diagnostic Lens Selector
Instructions
Select the flat and steep radius and eccentricities for each eye. When a value is selected, the border will turn gray. When all 4 boxes are populated, the Suggested Diagnostic Lens number and corresponding parameters will be displayed at the bottom. If the Estimated Initial Center Clearance is a negative number, bearing is expected on the steepest lens and you may want to consider a Custom Stable lens.
