TRANSIENT ADAPTATION OF THE EYES OF A MOTORIST
A DEVICE IS BEING DEVELOPED THAT WILL AID IN THE STUDY OF TRANSIENT ADAPTATION OF THE EYES OF A MOTORIST DRIVING ALONG A HIGHWAY AT NIGHT WHERE HE IS CONFRONTED WITH STREET LIGHTS AND THE HEADLIGHTS OF ONCOMING AUTOMOBILES. A GLARE METER WILL ASSESS THE STRAY LIGHT AT THE FOVEA AND A SECOND METER WILL MEASURE THE AVERAGE LUMINANCE OF A SMALL PORTION OF THE VISUAL FIELD CENTERED AROUND THE PRIMARY LINE OF SIGHT. THESE DEVICES WILL BE MOUNTED IN A FIXED POSITION IN THE AUTOMOBILE TO RECORD STRAY LIGHT AND AVERAGE LUMINANCE. THIS INFORMATION WILL BE FED INTO AN ELECTRONIC ANALOG COMPUTER THAT WILL EVALUATE THE STATE OF ADAPTATION AT THE FOVEA AND CONSIDER THE IMMEDIATE PAST HISTORY OF THE EYES OF THE OBSERVER.
