FIELD OF VIEW WITH AND WITHOUT MOTORCYCLE HELMETS

The total field of view for 19 experienced motorcyclists at 10 angular positions was obtained by moving a target along a circular perimeter and recording the angle at which it was first perceived. All subjects were tested with no helmet, two full coverage helmet models, two full facial coverage helmet models, and goggles. Along the horizontal plane, visual restriction was less than 3% with full coverage helmets are compared to no helmet. The full facial coverage helmets produced 7.3% and 21.9% lateral field reduction. The helmet with the large restriction was a "worst case" helmet representing a small percentage of helmet sales and typically used in off-street situations. Lateral vision with goggles was approximately equivalent to that achieved by the most restrictive helmet. /Author/
