Night-blind individuals often have restricted visual fields or other visual impairments that limit their ability to travel at night. The study reported here compared two night-vision devices: one wide-angle light and one with a high-intensity beam. It concluded that no one night light is best for all individuals and that depending on the cause of the night blindness, a smaller angle, high-intensity light may be more useful than a wider angle one.
