Show No State Tests Drivers On Night-Time Vision NEW YORK. Even though night-time auto accidents occur more frequently and cause more deaths than day-time crack-ups, no state at present tests drivers on their ability to see at night, Dr. James E. Lebensohn, of the Northwestern North-western university medical school, has revealed in an article, published pub-lished by the National Society for the Prevention of Blindness. In his article, Dr. Lebensohn reported re-ported that accidents at night cause twice as many deaths as those during the day-time. He also pointed point-ed out that although only one-third of the driving is done after dark, two-thirds of the traffic deaths occur oc-cur at night. Dr. Lebensohn said that the three most important visual factors fac-tors in night driving are: 1. ability to see well in poor light; 2. ability to see against glare; 3. ability to recover from glare. Tests to check those faculties should be included in regular drivers' examinations. Night-time accidents pile up a higher toll in deaths, injuries and property damage, Dr. Lebensohn said, because the driver's eye reacts re-acts more slowly as the amount of light decreases; therefore, the margin for error is smaller. 'The driver is allotted less time and space than in the day-time to avoid contact or reduce the force of the impact," he said. |
