Standardize Contrast Sensitivity Function (CSF) measurements with precision WebGL stimuli, advanced Bayesian adaptive methods, and local-first data integrity. Built for the future of clinical research.
A comprehensive toolkit for advanced psychophysical testing and longitudinal follow-up.
Real-time rendering of Gabor patches, Sloan letters, Landolt C, and swept-frequency gratings with high contrast resolution using noisy-bit dithering.
Interactive dashboards for psychometric function fitting, CSF curve modeling (DoG, Log-Parabola, Exponential), and longitudinal trend analysis.
Secure client-side data persistence using IndexedDB. All subject demographics, session history, and trial data remain on your device.
Leverage state-of-the-art adaptive procedures including qCSF, QUEST, and Psi Bayesian methods for rapid, information-gain driven thresholds.
Tailored interface for clinical trials: track treatment arms, dosages, vision prescriptions, and automated protocol compliance.
Optimized for desktop and tablet environments (iPadOS/Android) with touch-friendly controls and automated display calibration.
CSF Station is a research-grade web application designed to measure the Contrast Sensitivity Function (CSF) using advanced psychophysical methods. It is built for vision researchers and clinicians who require precise, efficient, and traceable visual function testing.
No. While CSF Station provides high-precision measurements, it is a research and clinical support tool. Final diagnosis and prescribing decisions must be made by qualified practitioners based on full clinical examinations.
We prioritize privacy and security. CSF Station uses a local-first data model, storing all subject and session data in your browser's IndexedDB. Data never leaves your device unless you explicitly choose to export or backup your database.
Supported stimuli include Gabor patches, Sloan letters, Landolt C, and Campbell-Robson charts. Testing methods range from traditional Staircase and Constant Stimuli to modern Bayesian adaptive procedures like qCSF, QUEST, and Psi.
Yes. CSF Station is fully optimized for mobile devices, including iPadOS and Android tablets. It features touch-enabled controls, automated hardware resolution detection, and full-screen modes for accurate measurements.
