To gain more insight into the relationship between foveal and peripheral refractive errors in humans, spheres, cylinders, and their axes were binocularly measured across the visual field in myopic,… Expand
Inter‐individual variability in the dynamics of natural accommodation in humans: relation to age and refractive errors.
1. To study the relationship between accommodation under natural viewing conditions, age and refractive errors, we have measured time courses of accommodation in thirty‐nine human subjects aged 5‐49… Expand
A paraxial schematic eye model for the growing C57BL/6 mouse
PURPOSE The mouse eye has potential to become an important model for studies on the genetic control of eye growth and myopia. However, no data are published on the development of its optical… Expand

Purpose Photorefraction is a convenient way to determine refractive state from a distance. It is, therefore, useful for measuring infants and noncooperative subjects. However, its reliability (or… Expand

PURPOSE Recent epidemiologic studies have shown that children who spend a higher proportion of time outdoors are less likely to develop myopia. This study was undertaken to investigate whether light… Expand
The effect of bright light on lens compensation in chicks.
PURPOSE It has been shown that sunlight or bright indoor light can inhibit the development of deprivation myopia in chicks. It remains unclear whether light merely acts on deprivation myopia or, more… Expand
Effects of longitudinal chromatic aberration on accommodation and emmetropization
PURPOSE Less accommodation was found when human subjects read in blue (peak at about 440 nm) than when they read in red light (above 600 nm; [Kroger & Binder, British Journal of Ophthalmology 84… Expand
An evaluation of the lag of accommodation using photorefraction
OBJECTIVE The lag of accommodation which occurs in most human subjects during reading has been proposed to explain the association between reading and myopia. However, the measured lags are variable… Expand
Accommodation, refractive error and eye growth in chickens
We raised chickens with defocusing lenses of differing powers in front of their eyes. For this purpose, small hoods made from soft, thin leather were carefully fitted to their heads. Lenses were… Expand
