Wilcoxon signed-rank (paired) test with Bonferroni correction for cheek and brow movements between expressions (eyebrow raise, frown, smile, and squeezed eyes) performed while wearing the glasses in different positions on the nose bridge (low, medium, and high). Statistical significance annotations: *if p ∈ [0.05, 10−2); **if p ∈ [10−2, 10−3); ***if p ∈ [10−3, 10−4); and ****if p ≥ 10−4.
