 | Thickness Methods |
The Thickness type exposes the following members.
Methods| Name | Description | |
|---|---|---|
  | ApproximateSagFormula |
Calculates an approximate sagittal depth. Inputs are surface power in diopters, lens diameter in millimeters and index of refraction.
|
| ApproximateThickness |
Calculates an approximate lens thickness. Inputs are surface power in diopters, lens diameter in millimeters, index of refraction and center OR edge thickness in millimeters.
|
| CenterThickness |
Calculates the edge thickness of a minus lens. Inputs are the front sagittal depth, back sagittal depth and edge thickness in millimeters.
|
| EdgeThickness |
Calculates the edge thickness of a minus lens. Inputs are the front sagittal depth, back sagittal depth and center thickness in millimeters.
|
| MinusPrismLensEdgeThickness |
Calculates the edge thickness of minus lens with prism. Inputs are the sagittal depth, minimum center thickness and prism base thickness in millimeters.
|
| PlusPrismLensCenterThickness |
Calculates the center thickness of a plus power lens with prism. Inputs are sagittal depth, minimum edge thickness and prism base thickness.
|
| PlusPrismLensThickestEdge |
Calculates the edge thickness of a plus lens with prism. Inputs are the prism base thickness and minimum edge thickness in millimeters.
|
| PrismPowerFromThickness |
Calculates the power of a prism based on it's thickness. Inputs are the thickness DIFFERENCE between the two edges, lens Diameter in millimeters and index of refraction.
|
| PrismThickness |
Calculates the thickness of a exclusively prismatic lens. Inputs are the prism power in diopters, lens diameter in millimeters and index of refraction.
|
| SagittalDepth(Double, Double) |
