 | Prism Methods |
The Prism type exposes the following members.
Methods| Name | Description | |
|---|---|---|
  | ApicalAngle |
Calculates what apical angle the prism will need to deviate a ray of light by a given amount. Inputs are degrees of deviation and index.
|
| EffectiveDecentration |
Calculates the effective decentration from the optical center of a spherocylinder lens in centimeters.
|
| EyeResolver |
Determines which eye is being calculated. Inputs are the prism base angle, as well as the vertical and horizontal base directions
|
| PrenticesLawCentimeters |
Calculates prismatic effect in diopters. Inputs are the lens power in diopters and distance from optical center in centimeters.
|
| PrenticesLawMillimeters |
Calculates prismatic effect in diopters. Inputs are the lens power in diopters and distance from optical center in millimeters.
|
| PrimsDeviation |
Calculates the angle formed by the emerging ray and the original ray path. Inputs are apical angle in degrees and index of refraction.
|
| PrismCentrad |
Calculates prism based on the centrad in diopters. Input is the angle of deviation in degrees.
|
| PrismDiopter |
Calculates prism diopters. Inputs are displacement of light ray in centimeters and distance from prism in meters.
|
| PrismDiopterApproximation |
Approximates the power of a prism in diopters. Inputs are the apical angle in degrees and index of refraction.
|
| PrismDisplacement |
Calculates displacement of ray in centimeters. Inputs are the prism's dioptric power and the distance in meters.
|
| PrismDistance |
Calculates the distance a light ray is from a prism in meters. Inputs are the prism power in diopters and the displacement in centimeters.
|
| ResolvingPrismHorizontal |
Resolves the horizontal component of a given power and angle. Inputs are prism power in diopters and angle in degrees.
|
| ResolvingPrismVertical |
Resolves the vertical component of a given power and angle. Inputs are prism power in diopters and angle in degrees.
|
| ResultantPrism |
Calculates resultant prism magnitude. Inputs are the horizontal and vertical prism components in diopters.
|
| ResultantPrismAngleLeftEye |
Calculates the angle of prism for the left eye (OS) in degrees. Inputs are the horizontal and vertical prism components in diopters.
|
| ResultantPrismAngleRightEye |
