Background: Motorcycle helmets are one of the most important protective gears in the automotive industry. However, some riders think they hinder their vision, which leads to helmet non-compliance. Hence, thorough research is required to evaluate the same. Aim and Objective: To assess the effect of full-face and half-face helmets on functional vision and visual reaction time (VRT). Setting and Study Design: Comparative experimental crossover study. Methods: The subjects aged between 18 and 35 years and who gave written consent to participate were included. Functional vision and VRT were assessed with and without the helmets. Helmets tested included a full-face helmet and a half-face helmet. Results: A total of 52 subjects aged 20 ± 1.5 years, participated in the study. Of those, 16 were males and 36 were females. The mean stereopsis without any helmet was 44.42 ± 6.3 arcs of second that reduced to 60.57 ± 13.34 arcs of second with a full-face helmet and to 60.38 ± 14.27 arcs of second with a half-face helmet. Repeated-measure analysis of variance showed a significant reduction in stereopsis in both types of helmets ( P < 0.05) as compared to without a helmet. However, contrast sensitivity, VRT, and visual field did not show any significant difference ( p > 0.05) when compared to the baseline or within the helmet types. Conclusion: The visor significantly affects the stereopsis while viewing through it. The study did not find the exact cause of this reduction, and hence, further evaluation is recommended.

“…[ 2 ] The field of view and use of helmets have received fair attention in the scientific literature. [ 5 ] McKnight et al [ 6 ] analyzed data for the actual causes of road accidents and concluded that 11% of the accidents were related to the rider's field of view. In recent times, Joshi et al .…”

“…Moreover, a common reason behind helmet non-use is a limited visual field, which certainly presents a problem because peripheral vision is an essential factor for safety in alpine skiing [10,11]. Advanced visual reaction time, visual memory, and visual discrimination are directly translated to improved sport performance and reduced locomotor injury risk [12].…”

The Influence of Protective Headgear on the Peripheral Vision Reaction Time of Recreational-Level Skiers

Alpine skiing is characterized by specific and dynamic conditions and demands constant processing of visual information and fast decision-making. A fast response time is necessary for protective movements which reduce the number and severity of additional head impacts. The apparent detriments to visual performance caused by protective headgear are concerning and should be considered moving forward in recreational alpine skiing. The aim of this study was to examine the effects of wearing the three most common combinations of protective headgear in skiing on the timing of visual stimuli perception and adequate response when simulating on-the-slope situations. The sample consisted of 45 recreational-level skiers (27 M, 18 F; age 30.6 ± 8.19 years) who had finished basic alpine skiing school, had been skiing 6–10 years continuously, and were students of Faculty of Kinesiology, University of Zagreb. They did not report any serious medical conditions regarding vision. The overall testing was conducted in the winter season during January and February of 2022. Reaction time on perceived visual stimuli was observed in a way that a skier was approaching behind a participant’s back from both the left and right side. A 2 × 3 (helmet*condition) mixed-model repeated-measures ANOVA was used to determine differences between helmet users and non-users in each tested condition. When observing the results, it was confirmed that the response time of the participants was the slowest when wearing a ski helmet and goggles combined. Furthermore, one of the most important findings was the determined differences in reaction time between helmet users and non-users, i.e., prior helmet users tended to react faster to the upcoming visual stimuli when wearing combined ski helmet and goggles. In the design and construction of the goggles, it is also necessary to pay attention to reducing the thickness of the frame in order to reduce the distance between the eye and the lens, which consequently reduces interference in the peripheral parts of the field of vision. In future studies, the same testing protocol with all the possible combinations of wearing a ski cap, a helmet, sunglasses, and goggles is necessary to gain a clearer insight into the effect of each item of headgear separately and in various combinations.

“…Moreover, common arguments for helmet non-use are impaired hearing and impaired vision [ 13 , 14 , 15 , 16 ]. In addition, it has been suggested that a helmet might alter skiers’ ability to sense the surroundings, potentially leading to dangerous situations.…”

The benefit of protective headgear for recreational skiers is an ongoing debate in the snow sports industry, and there are a lot of opposing opinions. Due to the dynamic conditions in which winter sports are performed, athletes demand rapid and constant processing of visual information. A sufficient level of anticipation helps athletes to properly position themselves to reduce the forces transferred to the head or even move to avoid a collision. To objectively identify the impact of protective headgear on the visual field when skiing, it is necessary to conduct suitable measurements. The sample consisted of 43 recreational-level skiers (27 M, 16 F; age 31.6 ± 8.23 years). A predefined testing protocol on an ortoreter was used to assess the visual field for three conditions of wearing protective headgear. Differences in perceived visual stimuli between the three conditions were evaluated by repeated measures analysis of variance (ANOVA). Based on the observed results, it can be concluded that the combination of wearing a ski helmet and ski goggles significantly negatively influences visual performance in a way that the visual field is narrowed, for both helmet users and non-users, only when comparing the tested conditions. When comparing helmet users and non-users, there are no differences in the amount of visual impairment; therefore, the habit of wearing a helmet does not influence the ability of perceiving visual stimuli.
