Comparison of (a) reaction time (ms) separated by rings (ring 3, ring 4, ring 5), (b) reaction time (ms) separated by upper and lower quadrants between baseline (BL; white), helmet only (H); light grey), helmet + clear visor (HCV; grey), helmet + smoke-tinted visor (HSV; black), and helmet + mirror-tinted visor (HMV; black striped) conditions. Data are presented as mean ± SD. * indicates significant difference from baseline (p < 0.05). # indicates significant difference from HO (p < 0.05). ‡ indicates significant difference from HMV (p < 0.05). ¥ indicates significant difference from ring 3 (p < 0.05). $ indicates significant difference from ring 4 (p < 0.05).
