“…These results are shown in table I and figures 1 and 2. Discussion The data confirm the finding of Misiak (1947) be seen that the partial correlations are of the same order of magni tude, except for those of Colgan where non-verbal intelligence is held constant. Here it is worth noting that the Wechsler Performance Score has been used, in the absence of data on the Progressive Matrices Test, which was employed by Lor anger and Misiak and by the present author.…”

“…The headaches relationship is strongly age sensitive while the eyestrain relationship is not so strong, suggesting that many other factors also influence eyestrain. This need not conflict with Prof Hopkinson's findings that complaints came from women and from the [35][36][37][38][39][40][41][42][43][44][45] Fi,~. A..P~vpor~acr~ of office workers in each age group who suffer from eyestrain (N = 626).…”

The factors influencing flicker sensitivity are reviewed. Sensitivity is increasing because of improving lighting standards and personal peak sensitivity occurs for people approximately 20 years old. There is wide variability between people and the effect of flicker is related to the individual threshold. Office surveys reveal that significant numbers of people see flicker and that this feature is associated with the 'unsatisfactory' ratings of the lighting. Some headaches and eyestrain are related to seeing flicker. Light modulation from fluorescent lamps at 50 and 100 Hz has been measured and the growth in the 50 Hz component with time has been studied. The 50 Hz component is the one which is normally seen. The lamp characteristics show this 50 Hz modulation to remain at a low value for the first 7-8000 hours operation and thereafter to rise more rapidly with operation. Planned lamp replacement is now essential.

“…It has been known for over 50 years that critical flicker fusion (CFF) is decreased in older adults (Coppinger, 1955; McFarland, Warren & Karis, 1958; Misiak, 1947). But only in the past 25 years has research comprehensively explored older adults’ problems in processing time-varying targets.…”

Given the increasing size of the older adult population in many countries, there is a pressing need to identify the nature of aging-related vision impairments, their underlying mechanisms, and how they impact older adults’ performance of everyday visual tasks. The results of this research can then be used to develop and evaluate interventions to slow or reverse aging-related declines in vision, thereby improving quality of life. Here we 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.
