In the first part of the study, the toric lenses were rotated, \u223c45\u00b0 in the infero\u2010temporal direction and a video recording of lens reorientation was made from which blink\u2010by\u2010blink measurements of lens orientation were taken.

Lenses showed more rotation during rather than between the blink (p &lt; 0.0001). Between blinks, AAfA and AOT showed significantly more rotation than PCT and PVT (p \u2264 0.04). There were no significant differences between lenses for rotation during the blink. The PB lenses showed faster re\u2010orientation further away from the zero position. AAfA showed no significant difference in rotation speed with varying orientation position. In Part 2, all the PB lenses rotated significantly more under the effect of gravity than the ASD lenses. The mean total rotation of the AAfA lenses, from their settled position, was 11.4\u00b0 compared with 25.9\u00b0 for PVT (p = 0.01), 18.4\u00b0 with AOT (p = 0.02) and 37.4\u00b0 with PCT (p &lt; 0.0002). The mean total rotation of the AAfA lenses, from their settled position, was 11.2\u00b0 compared with 32.8\u00b0 for PVT (p &lt; 0.001), 16.1\u00b0 with AOT and 33.1\u00b0 with PCT (p &lt; 0.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions.<\/jats:title>\n                    <jats:p>The four lens designs show similar re\u2010orientation speeds.
