The ability to drive safely is closely related to effective visual function. Approximately 90% of the information a driver receives is visual, making good eyesight essential for operating a vehicle. Key functions that contribute to safe driving include:
- Peripheral Vision: The awareness of the surrounding environment to detect potential hazards from the left and right sides.
- Visual Acuity: The clarity of an individual’s vision, which is essential for recognizing and reading road signs, cues from other drivers, as well as reading the dashboard and touch screens inside the vehicle.
- Scanning & Tracking: The ability to continuously monitor your surroundings while driving, including pedestrians and other vehicles.
- Contrast Sensitivity: The ability to distinguish objects from their background, especially at night time or in challenging weather conditions.
- Visual Perception Skills: The skills that help individuals interpret visual information – crucial for decision making while driving, such as understanding what a sign means even if partially covered by a tree.
- Depth Perception: The ability to understand the space and distance between objects. This is crucial for braking distance and understanding the space between yourself and other vehicles.
Conditions like macular degeneration can severely impact a number of these visual processes above, in turn, affecting an individual’s ability to drive. Understanding these effects and knowing when to seek assistance can help you or your loved one stay safe on the road.
Recognize The Warning Signs of Visual Decline
It’s important for drivers and their loved ones to understand the warning signs that may indicate a decline in visual functioning. Some of these signs can include:
- Changes in Depth Perception
- Inability to Read Signs at a Distance
- Difficulty Driving at Night
- Collisions or Near Misses
- Problems with Vision in Inclement Weather
- Difficulty Seeing Faded Lane Markings
If any of these signs are observed in either yourself or a loved one, it may be time to contact an Occupational Therapy Driver Rehabilitation Specialist (OT DRS) for a comprehensive driving evaluation.
