The effects of spectacle frames on field of vision.
Spectacle frames with thick frames and wide and low-set temples were obtained from an optical goods distributor. Peripheral visual fields were mapped with a Goldmann Projection Perimeter to determine if there was evidence of a safety hazard. A novel way of displaying visual fields was employed. Frame fronts caused more obstruction than temples, which were not found to be a particular problem. Large lenses and thin frames are still recommended for aviator's spectacles and sunglasses. Unusually wide, solid temples should not be worn while flying or driving.
