TLDR
In this paper, the authors evaluated a qualitative trend on using motion perception tasks as a potential visual perceptual correlates in screening elderly drivers who might have difficulty in driving and calculated a motion index score which was indicative of performance.Abstract:
Changes in the demographics indicates that the population older than 65 is on the rise because of the aging of the ‘baby boom’ generation. This aging trend and driving related accident statistics reveal the need for procedures and tests that would assess the driving ability of older adults and predict whether they would be safe or unsafe drivers. Literature shows that an attention based test called the useful field of view (UFOV) was a significant predictor of accident rates compared to any other visual function tests. The present study evaluates a qualitative trend on using motion perception tasks as a potential visual perceptual correlates in screening elderly drivers who might have difficulty in driving. Data was collected from 15 older subjects with a mean age of 71. Motion perception tasks included—speed discrimination with radial and lamellar motion, time to collision using prediction motion and estimating direction of heading. A motion index score was calculated which was indicative of performance ...read more

Aging and vision.
TL;DR: In this article, the authors summarize salient developments in research on aging and vision over the past 25 years, focusing on spatial contrast sensitivity, vision under low luminance, temporal sensitivity and motion perception, and visual processing speed.

Evidence from a cohort of able bodied adults to support the need for driver training for motorized scooters before community participation.
TL;DR: Basic driving skills for motorized scooters need to be taught and learned with assessment for competency recommended before unrestricted community driving is allowed.

Visual motion perception predicts driving hazard perception ability
TL;DR: This work aims to examine the basis of previous findings of an association between indices of driving safety and visual motion sensitivity and to examine whether this association could be explained by low‐level changes in visual function.

TL;DR: In this paper, the authors identify whether measures of visual processing ability, including the useful field of view test, are associated with crash involvement by older drivers and find that older drivers with a 40% or greater impairment in the SVM were more likely to incur a crash during 3 years of follow-up, after adjusting for age, sex, race, chronic medical conditions, mental status, and days driven per week.

Visual attention problems as a predictor of vehicle crashes in older drivers.
TL;DR: The identification of a visual attention measure highly predictive of crash problems in the elderly is pointed to a way in which the suitability of licensure in the older adult population could be based on objective, performance-based criteria.

Contrast sensitivity throughout adulthood
TL;DR: Reduced retinal illuminance characteristic of the aged eye could account for a large part of older adults' deficit in spatial vision, but appeared to play little role in their deficit in temporal vision.
