The dataset provides contrast sensitivity results measured under different conditions, displayed on a LCD display (ViewPixx/3d, VPixx Technologies Inc., Saint-Bruno, Canada). All test procedures were based on the software Matlab (MATLAB R2020a, MathWorks Inc., Natick, MA, USA) using the Psychophysics Toolbox Version 3 (Brainard, 1997 and Kleiner et al., 2007). Contrast sensitivity was assessed by using a new contrast sensitivity test based on the method of adjustment incorporating Gabor patches of different spatial frequencies (see test conditions below) and orientations (0°, 45°, 90° and 135°).
The data is structured into subjects ("Subject"), their refraction group ("Refraction Group": myope and non-myope) and the test / stimulation conditions.
Test and stimulation conditions include three variables :
- Location (2 levels: Optic nernve head (ONH) and screen full-field (FF)),
- Wavelength range (4 levels: short-wavelengths (S), middle-wavelengths (M), long-wavelengths (L) and polychromatic light (P)),
- Spatial frequecy in cycles per degree (cpd) (5 levels: 3 cpd, 6 cpd, 12 cpd, 18 cpd and 24 cpd)
