Available tools
- Acuity Chart Distance Reference Label Record an explicit acuity-chart distance reference without converting visual acuity or choosing a testing distance.
- Astigmatic Power One Meridian Term Tool Paraxial sphero-cylinder meridian power S+C*sin²(theta-axis) in radians, without a prescription recommendation.
- Chart Distance Unit Basis Flag Tool Compare a supplied chart distance to an explicit reference after unit conversion; no acuity score is inferred.
- Cornea Radius Unit Crosswalk Convert an explicitly supplied corneal radius between millimeters and meters without estimating refractive power.
- Corneal Curvature Radius Diopter Reference Tool Conventional index-minus-one over radius power using a caller-supplied keratometric index, not true two-surface corneal power.
- Eye Tracker Screen Gaze Angle Term Tool Flat-screen geometric gaze offsets from explicitly calibrated coordinates and viewing distance, not an eye-tracker calibration or diagnosis.
- Eyetracker Reference Origin Shift Tool Translate supplied eye-tracker coordinates between origins in one coordinate basis.
- Lens Thickness Optical Path Factor Tool Uniform-index slab optical path and excess over a supplied surrounding medium, not a full crystalline-lens model.
- Ocular Angle Kappa Sign Label Label a supplied ocular angle and its explicit positive-sign convention without deriving an angle from anatomy.
- Ocular Axis Orientation Sign Tool Relabel supplied axis components under explicit orientation signs without inferring eye laterality.
- Ocular Laterality Label Token Tool Classify an explicitly supplied ocular record label under disjoint caller-provided vocabularies.
- Ophthalmic Chart Distance Letter Height Factor Tool Geometric equal-angular-size chart scaling, without asserting clinical equivalence between chart designs.
- Ophthalmic Device Calibration Timestamp Label explicitly recorded calibration timestamp text without interpreting validity or setting a service interval.
- Ophthalmic Meridian Orthogonal Pair Pair an explicitly supplied zero-inclusive half-turn axis with its orthogonal meridian without interpreting ocular power.
- Ophthalmic Refraction Cylinder Sign Label Label the sign and magnitude of a supplied cylinder power without transposing or recommending a prescription.
- Ophthalmology Interpupillary Half Distance Offset Tool Compare explicit total and monocular distance records, without selecting a spectacle fit or determining patient measurements.
- Pupil Edge Blur Uncertainty Term Tool Propagate supplied bounded edge-location errors into a diameter interval, without estimating blur from an image.
- Pupil Ellipse Axis Ratio Tool Calculate pupil ellipse axis ratio from explicit caller-supplied inputs.
- Retina Disc Diameter Scale Express a supplied retinal image distance in explicitly measured disc-diameter units without anatomical size calibration.
- Retinal Image Angle Length Factor Tool Supplied reduced-eye planar scale times angle or tangent, without an individual eye biometry or retinal magnification model.
- Retinal Image Eye Side Tag Attach explicit eye laterality to a retinal image record without identifying image orientation or anatomy.
- Retinal Mask Support Share Tool Account for explicit research mask areas and support flags without retinal image interpretation.
- Retinal Pixel Angle Factor Tool Apply a supplied retinal research image angular calibration, without inferring retinal anatomy or disease.
- Retinal Scan Bscan Spacing Budget Tool Explicit endpoint-inclusive versus equal-cell B-scan placement convention, without an acquisition-density recommendation.
- Snellen Decimal Logmar Source Crosswalk Tool Numerical Snellen fraction, decimal and logMAR crosswalk, excluding counting-fingers or other non-Snellen categories and clinical interpretation.
- Tear Film Research Breakup Time Gap Tool Research event-time interval from supplied blink and image observations, without detecting tear-film breakup or applying a clinical cutoff.
- Visual Angle Stimulus Size Tool Return the exact centered planar stimulus angular width from supplied compatible dimensions, without an acuity score.
- Visual Field Solid Angle Small Angle Term Tool Solid angle of an ideal centered rectangular angular patch versus its small-angle product, without a visual-field test interpretation.
- Visual Grid Origin Gap Tool Calculate visual grid origin gap from explicit caller-supplied inputs.
- Visual Stimulus Frame Slack Tool Calculate visual stimulus frame slack from explicit caller-supplied inputs.
