Mascara has been proposed as a simple approach to correct for eye-motion artefacts via detection of induced B0 changes when blinking. In this study we measure the B0 changes from 10 different types of mascara. We can differentiate three different categories of mascara, in which in violation of Murphy’s law the cheapest brands result in the strongest B0 field changes.
