      <title>THE USEFUL FIELD OF VIEW TEST: A NEW TECHNIQUE FOR EVALUATING AGE-RELATED DECLINES IN VISUAL FUNCTION</title>
      <link>https://trid.trb.org/View/390472</link>
      <description><![CDATA[Many older adults eventually experience difficulty in everyday visual activities, prompting them to consult with an eye care specialist. In some cases, a thorough examination may reveal no clinical basis for these difficulties. New techniques for evaluating age-related declines in visual function have substantiated the existence of deficits in visual attention that are not adequately captured by standard clinical measures, and which are predictive of real world problems in driving and mobility. These new techniques may serve an important function in guiding the diagnosis, and treatment of those older adults experiencing functional visual problems.]]></description>

      <title>EFFECTS OF ALCOHOL ON EVENT-RELATED BRAIN POTENTIALS PRODUCED BY VIEWING A SIMULATED TRAFFIC SIGNAL</title>
      <link>https://trid.trb.org/View/290304</link>
      <description><![CDATA[The P-300 event-related brain potential was monitored during simulated traffic signal tasks for 10 subjects who were tested at three levels of mean blood alcohol content: 0.00 %, 0.06 %, and 0.13 %.  A significant increase in latency occurred for the 0.13 % level indicating that an increased mental processing time was required to determine if a red or a green light had been presented.]]></description>

      <title>OPTOMETRIC EXPERT TESTIMONY. FOUNDATION FOR THE HORIZONTAL GAZE NYSTAGMUS TEST</title>
      <link>https://trid.trb.org/View/290309</link>
      <description><![CDATA[The courts require that a foundation be laid for admission of the Horizondal Gaze Nystagmus Test into evidence.  Some courts will not accept police officers as experts, but will instead require that an optometrist provide the necessary foundation.  The optometrist will be expected to establish the correlation between nystagmus and alcohol consumption, and to educate the court of the desirability of the test for use by the law enforcement community.  The optometrist should prepare prior to trial to assist the prosecutor in achieving these goals.]]></description>

      <title>VISUAL ACUITY AS A FUNCTION OF AGE</title>
      <link>https://trid.trb.org/View/181380</link>
      <description><![CDATA[The literature relating visual acuity and the aging process is reviewed. The Snellen fraction, parameters affecting visual acuity and difficulties in comparing different studies in visual acuity are discussed.  Visual acuity was found to be a poor 20/1,000 to 20/800 at birth but improved to an almost normal acuity of 20/20 during the first year of life and remained relatively constant from 40 to 50 years of age. There was a moderate but steady decline in acuity as a person ages above 60 and on to the age of 80. The disease and physiological etiologies for this loss in acuity are provided. Methods which may be used to maintain or improve visual performance with age are suggested.]]></description>

      <title>WAXED WINDSHIELDS ARE HAZARDOUS IN THE RAIN</title>
      <link>https://trid.trb.org/View/45020</link>
      <description><![CDATA[Seven automobiles were washed and waxed at four car washes. Photographic determinations were made of the glare produced by the wet or dry waxed windshield in a headlight beam. When wet, the waxed windshields scattered three times more light than in the normal human eye.  The wet wax scattering was 24.8 times higher than when dry.  No wax residues should be permitted on windshields and the National Highway Traffic Safety Administration should issue a mandatory windshield cleaning requirement after waxing.

      <title>A MODEL STUDY OF FACIAL INJURY CAUSED BY IMPACT WHILE WEARING AN OPTHALMIC FRAME</title>
      <link>https://trid.trb.org/View/65485</link>
      <description><![CDATA[Damage to facial tissue caused by an opthalmic frame when there is impact to the face was studied by means of a paraffin-covered mannequin head.  Under mild conditions of impact it was easily observed that metal frames and metal components do more tissue damage than is done by a zylframe. A series of the commonly dispensed frames was compared for facial injury potential caused by impact to the face. /Author/]]></description>

      <title>VISUAL ACUITY AND HIGHWAY ACCIDENTS</title>
      <link>https://trid.trb.org/View/67086</link>
      <description><![CDATA[An analysis of binocularly obtained visual acuity test scores of 13,786 automobile drivers was made in terms of the number of accidents reported by each driver during a 12 month period.  For each of eight different age categories the drivers were classified as having poor acuity if their scores were below the lower quartile, and as having good acuity if their scores were above in median.  The percent of drivers with poor acuity who reported three or more accidents was approximately double the percent of drivers with good acuity who reported three or more accidents.  The proportion with poor acuity who reported two accidents was approximately 50% greater than the proportion for those with good acuity.  These differences were statistically significant and prevailed at all age levels above 19 years. the differences in proportions reporting one accident and no accident for the poor and good acuity categories were not significant. /Author/]]></description>

      <title>SPECTACLE FRAMES REDUCE THE FIELD OF VISION: A DRIVING HAZARD</title>
      <link>https://trid.trb.org/View/107823</link>
      <description><![CDATA[THE IMPORTANCE OF ADEQUATE PERIPHERAL VISION IN DRIVING MAY BE NEGATED BY STYLISH SPECTACLE FRAMES. TESTS WERE MADE WITH HIGH SCHOOL STUDENTS WEARING VARIOUS SPECTACLE FRAMES, AND WITHOUT SPECTACLES. RESULTS STRESS THE IMPORTANCE OF FOUR FEATURES TO BE CONSIDERED WHEN PRESCRIBING GLASSES WHICH WILL BE WORN WHILE DRIVING: LARGE LENS AREA; THIN LENS RIM AT THE SIDE AND BOTTOM; THIN, HIGH TEMPLES; AND LENS SET CLOSED TO THE EYE. SINCE MOST SPECTACLES REDUCE THE FIELD OF VISION TO A CERTAIN EXTENT, DRIVERS SHOULD BE ADVISED TO TURN THEIR HEADS FURTHER TO THE SIDE WHEN CHECKING FOR DANGER. /HSL/]]></description>

      <title>DISAPPEARING HEADLIGHTS: AN EVALUATION OF THE EFFECTIVENESS OF A NEW STYLING TREND IN AUTOMOBILES</title>
      <link>https://trid.trb.org/View/113342</link>
      <description><![CDATA[THE AUTHOR EVALUATES THE EFFECTIVENESS OF DISAPPEARING HEADLIGHTS. IN SUPPORT OF HIS STATEMENT "HEADLIGHT CONCEALMENT....OFFERS NO ADVANTAGES BEYOND NOVELTY," HE POINTS OUT THE FOLLOWING DISADVANTAGES: (1) THEY MAKE THE DIRECTION OF A MOVING CAR HARD TO DETECT; (2) THE HEADLIGHTS ARE OFTEN AN EFFECTIVE DEVICE TO USE AS A WARNING SIGNAL AND WITH DISAPPEARING HEADLIGHTS, FLASHING ONES LIGHTS REQUIRES SEVERAL SECONDS TO GET THEM UNCOVERED; (3) CONCEALED HEADLIGHTS ARE NOT CLEANED BECAUSE THEY ARE NOT NOTICED OR EXPOSED TO RAIN AND THE ACCUMULATED DIRT CAUSES GLARE; AND (4) THERE IS ALWAYS THE POSSIBILITY OF MECHANICAL FAILURE (THIS OCCURRED IN THE 1968 FORD MOTOR COMPANY'S COUGARS WHICH WERE RECALLED BECAUSE THE LIGHTS FAILED IN AN UNSAFE POSITION, THAT IS, THEY WOULD NOT OPEN). /SRIS/]]></description>
