Eye Diagnostics TRIZ Cases
- Rotating Light Array Ophthalmic Device for Low-Brightness Eye Inspection
A rotationally mounted linear array of light sources projects concentric rings onto the eye to enable precise optical measurements.
- Extreme Gaze Angle Detection for Powered Ophthalmic Lenses
Powered ophthalmic lenses detect extreme gaze angles using iris-facing photodetectors to trigger focal state changes, reducing manufacturing complexity.
- Compact Eye Exam Instrument Using Convex Reflector
A convex reflector folds the optical path to reduce instrument footprint while maintaining high-contrast image projection accuracy.
- Dual-Angle Ocular Scattering Measurement System
Segmenting detection into narrow and wide angular ranges resolves indirect assessment limitations for precise ocular scattering quantification.
- Adjustable Illumination Pattern for Eye Tracking Stray Light
A head-mounted optical measuring device uses an adjustable illumination unit to create a well-defined pattern for eye parameter capture.
- Optical Coherence Tomography Dual-Band Sampling for Extended Depth
Dual-band spectral sampling combines broadband sparse and narrowband dense data to reconstruct high axial resolution images.
- Ophthalmologic Apparatus Light Exposure Reduction
Second control unit decreases light amount irradiating the eye to be inspected after finishing a first scan and before starting a second scan.
- Ophthalmic Analysis System Interferometric Correction
A processing device corrects image data sets using interferometric measurement data to enhance geometric accuracy.
- Head-Mounted Display Eye Shift Correction
A head-mounted display detects user gaze shifts to adjust virtual object positioning for accurate alignment.
- Visual Field Testing Apparatus Color Sensitivity
- OCT Apparatus 3D Scan to Extract High-Fidelity 2D Images
An OCT apparatus captures three-dimensional tomographic images and extracts two-dimensional slices for display.
- Multi-Wavelength Visual Acuity Testing for Myopia Monitoring
Automated home testing detects myopia progression by analyzing chromatic aberration across multiple color wavelengths, reducing reliance on clinical visits.
