Eye Diagnostics TRIZ Cases
- Optical Biometer Partial Annular Light Source
Segmented light source and movable reference arm resolve optical path modulation range limits while maintaining measurement precision.
- Age-Adjusted Target Screening for Ophthalmic Fatigue
Adjusting target size and position by age prevents overestimated accommodation distances that cause prescription errors.
- Ophthalmologic Apparatus Chin Rest Elevation Adjustment
Integral elevation adjustment of chin and forehead rests accommodates non-perpendicular facial alignment for elderly patients.
- Variable Power Measuring Lens for Higher Order Aberration Correction
A measuring instrument with a lens of gradually changing strength determines higher order aberration corrections through subjective refraction.
- Inflatable Ophthalmic Mask with Sealed Cavities
An inflatable mask creates sealed ocular cavities to prevent cross-contamination while stabilizing the patient for accurate measurements.
- Sports Glasses Optical Simulation via Afocal Lenses
Afocal demonstration lenses simulate magnification and distortion to predict wearer tolerability, reducing asthenopic complaints from skewed lens geometry.
- Binocular Eyeglass Simulation with Unified Accommodation
A binocular eyeglass simulation method calculates lens distortion and blur using unified eye accommodation for accurate stereoscopic viewing.
- Digitally Controllable Mask for Ophthalmological Eye Inspection
Electronic signal control replaces mechanical apertures in ophthalmological apparatuses, eliminating manual adjustment requirements.
- Perimeter Visual Field Database Segmentation for Glaucoma Diagnosis
A perimeter device segments measurement results into distinct databases for normal and glaucomatous eyes to enable accurate diagnostic evaluation.
- Conical Frustum Meniscus Lens for Ophthalmic Stability
Conical frustum meniscus wall resolves ophthalmic size constraints by enhancing optical power and stability through electrostatic control.
- Subjective Optometry System with Identifier-Based Data Retrieval
A subjective optometry system uses readers to acquire objective measurement and previous glass data for initial calibration settings.
- Eye Tracking System for Simultaneous Multi-Target Visual Recognition
A characteristic testing system uses polar coordinates to detect line of sight direction and visually recognize multiple simultaneous targets.
- Ophthalmologic Imaging Tracking Controller for Scan Position Stability
A tracking controller maintains scan position relative to a photographing portion using real-time front images from an observing optical system.
- Swept Source Interferometry Arbitrary Sweep Patterns
Arbitrary sweep patterns modulate wavelength output to attenuate moving scatterer signals, reducing motion artifacts in swept-source interferometric imaging.
- Computer Eye Models for Intraocular Lens Peripheral Vision
Computer eye models simulate intraocular lens optical performance to reduce peripheral aberrations caused by anterior corneal geometry variations.
