Contrast Sensitivity

About

Measure how well subtle differences in visual contrast can be detected with a fast, easy-to-use edge orientation test. Contrast Sensitivity Test presents progressively lower-contrast edges in different orientations. Simply identify the direction of each edge and the app automatically adjusts the difficulty to determine a contrast sensitivity score. Simple to use Clear instructions, large response controls and a straightforward testing sequence make the assessment easy to complete. Standardised testing Screen brightness and stimulus presentation are controlled during each test to support consistent, repeatable measurement. Clear results Results are presented in decibels (dB), with published age-based Melbourne Edge Test reference data available for context. Designed for repeat testing A quick, structured format makes it easy to repeat the assessment and observe changes over time. Built around established methods The testing approach uses a four-choice edge orientation task based on established contrast sensitivity assessment principles. Contrast Sensitivity Test is part of the NeuroTools collection of digital tools for measuring neurological, sensory and functional performance. Results are provided for informational and assessment purposes and should be considered alongside other relevant information.
