Difficulty Driving at Dusk or Dawn? There is evidence that the lenses of the eyes become yellow and less transparent with age, and the pupils become smaller and less able to dilate in dim light. This can make driving at dusk or dawn problematic. Color Deficiency Color deficiency (blindness) may cause problems when identifying traffic signals or brake lights of other vehicles while driving. With cataracts, your ability to tell the difference between colors gradually decreases. Contrast Sensitivity Contrast sensitivity is the visual ability to see objects that are not outlined clearly or do not stand out from their background. Examples: Difficulty seeing pedestrians walking along poorly lit roadways and road signs in fog or at night. Useful Field of View Useful field of view refers to the amount of visual information that can be processed in a brief glance using both eyes. It is directly related to your ability to process information quickly and accurately. It takes less time to simply see and identify a single object than it does to divide your attention between two or more objects. The ability to process information gradually slows with age in most individuals, particularly for situations in which the environment is very complex. Examples: You can identify and react relatively easily to a stop sign at an empty intersection. If you add a pedestrian crossing in front of you and an oncoming vehicle making a left turn into the intersection, it can become much more complicated. Depth Perception Depth perception gives you the ability to judge the distance of objects in relation to yourself, especially when those objects are moving toward or away from you. Example: Depth perception is important in judging the distance and speed of approaching vehicles when merging or turning. Peripheral Vision Peripheral vision is the ability to see outside your immediate central field of view to either side or above or below. Example: Seeing a vehicle approaching you from either side, without having to take your attention away from what is in front of you. AARP DRIVER SAFETY 16 HOW DO WE NAVIGATE CHANGES? 2 1 2 3 4 5 6
