Information on vision test performance and personal and driving habits was obtained for 17,769 California drivers and was compared with their driving records, i.e., accidents and convictions for traffic citations. Of the vision tests evaluated, dynamic visual acuity is by far the one most closely related to driving record, followed by static visual acuity, visual field, and “night vision.” The results show that mileage, age, and sex are also important factors influencing driving record, and that conviction experience is a much more stable driving record variable than accident experience.

Limited research exists examining self-perceived vision and driving ability among individuals with glaucoma, and this study assessed the relationship between glaucoma, visual field, and visual acuity with driving capability. 137 individuals with glaucoma and 75 healthy controls were asked to evaluate self-rated vision, self-perceived driving ability, and self-perceived distracted driving. Visual acuity and visual field measurements were also obtained. Multivariable linear regressions were run to test each visual measure with driving outcomes. The average age was 72.2 years, 57.3% were male, and 72.5% were White. There were significant associations for a one-point increase in visual field and quality of corrected vision (RR = 1.06; 95% CI = 1.03–1.10), day vision (RR = 1.05; 95% CI = 1.03–1.08), night vision (RR = 1.08; 95% CI = 1.05–1.13), visual acuity score and higher quality of corrected of vision (RR = .41; 95% CI = .22-.77), day vision (RR = .39; 95% CI=.22–.71), and night vision (RR = .41; 95% CI = .18–.94); visual acuity score and ability to drive safely compared to other drivers your age (RR = .53; 95% CI = .29–.96). Individuals with poorer visual acuity and visual fields rate their vision and ability to drive lower than those with better vision, and this information will allow clinicians to understand where to target interventions to enhance safe driving practices.

Abstract Retinitis pigmentosa is an inherited neurodegenerative disease of the retina. We investigated smoking as a modifiable environmental factor for the progression of this currently untreatable disease. Clinical data, smoking history, macular function and morphology including visual acuity, visual field sensitivity, ellipsoid zone width and central retinal thickness were investigated. Association between pack × years and these parameters were evaluated using generalized estimating equation models to adjust confounding factors such as age and sex. A total of 410 patients with retinitis pigmentosa (≥20 years old; 209 female) were included, 164 had a smoking history. Patients without smoking history revealed a better visual acuity than smokers (0.39 versus 0.57, P = 0.001). The pack × years index was associated with worse visual acuity and thinner central retinal thickness after adjusting for age and sex (P = 0.0047 and 0.0099, respectively). Visual field and ellipsoid zone width showed a non-significant decline with increasing pack × years. This study indicates an association of smoking with worse macular function and structural integrity in retinitis pigmentosa patients, and hence a potential detrimental effect of smoking on the disease course.

Age And Sex

Using a Landolt ring with a gap of 40' of arc which moved at a decreasing velocity until the gap was discriminated, we measured the dynamic visual acuity of 826 subjects, males and females ages 5 to 92 years, and found rapid development between the ages of 5 and 15 years. This experiment showed that dynamic discrimination peaked at age 15 and then declined at a constant rate from age 20 on. The discrimination of male subjects was superior to that of female subjects at most ages, but a significant sex difference was observed only at age 5. We speculate that males may have better discrimination than females but variability is substantial.

Government Data

This paper reports on a comprehensive literature review of the older driver and older commercial driver literature. The review included sources of data from private and government data bases, empirical research published in public journals, and existing commercial vehicle driving task analyses. The review uncovered key abilities which degrade with age, including: static visual acuity, dynamic visual acuity, contrast sensitivity, useful field of vision, field dependence, depth perception, glare sensitivity, night vision, audition, reaction time, multilimb coordination, control precision, decision-making, selective attention, and attention sharing. The review also sought to identify which of those abilities might effect the performance of critical commercial driving tasks. Although much investigation has been done of older person abilities, most of the studies have looked at persons in either medical or judicial systems. We found little data on driving degradation of older but healthy drivers.
