It is believed that contact lenses are better for sports than spectacles. However, there are few quantitative studies to back up this claim. There are multiple hypothesized causes for decreased performance in spectacles, such as prismatic deviation, chromatic aberrations, and restricted field of view with a frame. The purpose of this study was to investigate if there is a difference in performance between contact lenses and spectacles while performing a rapid pointing task. Subjects were tested by using an AcuVision 1000, which required them to point and touch targets presented to them rapidly. Subjects performed this task in both contact lenses and spectacles while wearing a tracker that monitored their head movement. They were given a trial run before scoring to allow for learning of the device and task. The targets were presented at an interval of 0.80 seconds, with the next target appearing either when time had expired, or when the current target was hit. The printout from each trial showed the number and location of correct, late, and missed targets. The number of correct, late, and missed targets were compared between contacts and spectacles, as was the time to complete the task. The mean time of completion was faster with contact lenses by 1.5 seconds. The total number of correct responses overall was significantly higher in contact lenses (+5.32 ± 7.60), the total number of missed responses was significantly lower (-5.16 ± 7.46), and the number of late responses were virtually the same (+0.16 ± 8.08). When looking at the central targets of the AcuVision 1000, there were more correct responses (+1.581 ± 5.188) and less late responses (-0.87 ± 5.80) in contact lenses with a similar number of missed responses when compared to spectacles (-1.032 ± 2.938). When looking at the peripheral targets, the number of correct targets was higher (+3.42 ± 5.45) while the number of missed targets was lower (-4.10 ± 6.12) in contact lenses, with a similar number of late responses (+0.677 ± 5.128). We did not find a significant difference between spectacles and contact lenses when comparing refractive errors, which leads us to believe that chromatic aberrations and prismatic effect did not play a role in the diminished performance in spectacles found in this study. The difference in performance between contact lenses and spectacles is likely due to the constraints of the frame, especially while turning the head towards targets.
