Tiivistelmä väitöstutkimuksesta:
When we think about testing vision, most of us imagine reading letters on a chart. But seeing well in everyday life, like driving safely, spotting pedestrians, or recognizing faces is about much more than that. Despite this, most rules and regulations for driving licenses still rely on these simple tests.
This dissertation looks for better ways to understand how people really see and function. First, a review of existing studies was done to find out which vision and cognitive tests are commonly used to assess fitness to drive, and which tests research says are related to driving performance. The review showed that the link between vision, cognition and driving is complex and depends on many factors, including disease severity and compensational skills.
Next, the tests that were most important according to research were included in a study with glaucoma patients and healthy participants in which all participants completed neuropsychological tests, vision tests and drove in a driving simulator. Interestingly, both groups performed similarly in the driving simulator. The results suggested that some cognitive tests, like the Trail Making Test, can be affected by visual field loss and should be interpreted with caution.
Finally, four new portable tests were assessed to measure everyday visual skills like reaction time, face recognition, and visual search and a visual field test that also monitors compliance using a webcam. These tests proved reliable and consistent.
Together, the findings show that real-world vision is more than what an eye chart can measure and that understanding this difference can help create fairer, more accurate ways to assess how people see and function in daily life.
