Optometry Tools
Browse all available optometry tools.
Available tools
- Chart Acuity Step Budget Tool Count supplied chart index steps inclusively; no visual acuity conversion or scoring is assumed.
- Contact Lens Parameter Unit Label Record supplied contact-lens parameter and unit wording without choosing a lens parameter.
- Eye Dominance Supplied Test Code Tool Retain an explicitly supplied test response without inferring dominance.
- Frame Decentration Reference Gap Tool Compare supplied bench frame and pupil coordinates in one axis basis.
- Frame Optical Center Decentration Reference an explicit optical-center coordinate to a supplied frame center and sign convention without selecting lens placement.
- Lens Axis Wrapped Angle Tool Wrap an explicitly supplied unoriented research axis to a half-turn coordinate; no prescription is generated.
- Lens Base Curve Supplied Index Crosswalk Tool Same-curvature refracting-surface power under explicitly supplied indices, without selecting a lens base curve.
- Lens Blank Edge Clearance Margin Compare explicit lens-blank and required diameters without determining frame tracing, optical centering, or dispensing suitability.
- Lens Cylinder Axis Unit Flag Tool Convert a supplied axis unit and optionally normalize a 180-degree orientation; no prescription calculation.
- Lens Edge Center Thickness Geometry Term Tool Ideal spherical-surface sagittae with an explicit convex/concave thickness convention; negative edge thickness exposes inconsistent model dimensions.
- Lens Meridian Power Pair Return explicit spherocylindrical principal-meridian powers and the orthogonal axis without prescribing lenses.
- Lens Power Unit Reference Tool Compare supplied signed optical-power units to an explicit reference without a prescription or lens recommendation.
- Lens Prescription Plusminus Axis Token Tool Parse an explicit signed sphere/cylinder and integer axis token without selecting a prescription.
- Lens Transposition Cylinder Axis Wrap Tool Algebraic sphero-cylinder transposition with axis normalized to [0,180), not a prescription recommendation.
- Near Target Angular Size Tool Compute exact geometric angular extent of a centered planar target from compatible supplied dimensions.
- Optical Axis Reference Gap Tool Calculate optical axis reference gap from explicit caller-supplied inputs.
- Optometric Acuity Log Scale Step Factor Tool Apply an explicit logMAR step without selecting a chart scoring convention.
- Optometric Chart Distance Acuity Factor Tool Scale an explicitly calibrated Snellen chart fraction for a supplied test distance.
- Optometric Trial Frame Vertex Reference Tool Paraxial thin-lens vergence transfer F/(1-dF) through signed distance d, without a patient vertex-distance prescription.
- Optometric Uncorrected or Corrected Tag Label explicitly recorded optical correction status without interpreting acuity or treatment effect.
- Optometry Device Photometric Reference Gap Tool Calculate optometry device photometric reference gap from explicit caller-supplied inputs.
- Prism Base Axis Sign Token Tool Relabel supplied prism components under explicit signs without deriving a lens prescription.
- Prism Base Direction Code Label a supplied prism-base code and check an explicit code list without computing or recommending prism correction.
- Prism Power Decentration Prentice Term Tool Prentice thin-lens prism product with millimeters converted to centimeters; sign follows the supplied lens power and displacement, without patient base-direction assignment.
- Pupil Center Coordinate Gap Tool Calculate pupil center coordinate gap from explicit caller-supplied inputs.
- Spectacle Asymmetric Frame Decentration Pair Tool Explicit planar model decentration and conservative circular-blank budget, without selecting spectacle fitting measurements.
- Spectacle Bridge Fit Clearance Term Tool Audit explicit planar bridge/support dimensions without a fitting recommendation.
- Spectacle Fitting Cantilever Offset Gap Tool Calculate spectacle fitting cantilever offset gap from explicit caller-supplied inputs.
- Spectacle Frame Effective Diameter Clearance Tool Residual circular blank clearance after supplied frame effective diameter, planar decentration and radial allowance.
- Spectacle Pantoscopic Height Projection Term Tool Rigid planar tilt of a supplied frame height about an explicit pivot.
- Visual Stimulus Angular Step Tool Convert a supplied research stimulus coordinate step under an explicit angular calibration, without an acuity interpretation.
- Visual Stimulus Distance Factor Tool Calculate visual stimulus distance factor from explicit caller-supplied inputs.
- Visual Test Support Share Tool Calculate visual test support share from explicit caller-supplied inputs.
