About this trial
The goal of this clinical trial is to evaluate the glare protection provided by two filters compared to no filter. Using the Lumiz 100™ device (a headset with gradually increasing light), participants will measure their discomfort thresholds under three different conditions (one per filter). Each measurement will be repeated three times. The study requires a single visit of 2 hours for each participant. Glare protection will be quantified by comparing discomfort thresholds across the no-filter condition and the two studied filters.
