Journal ArticleDOI
The shape of the anterior and posterior surface of the aging human cornea.
TL;DR: The shape of the anterior corneal surface provides no definitive basis for knowing the asphericity of the posterior surface and the results show the effective refractive index is 1.329, which is lower than values commonly used.
Journal ArticleDOI
Change in shape of the aging human crystalline lens with accommodation
TL;DR: The results show that during accommodation there is a decrease in both the anterior and the posterior radius of the lens, although the change in mm per diopter of the latter is much smaller, and an increase in the equivalent refractive index during accommodation was determined.
Journal ArticleDOI
Two factors in visual fatigue caused by stereoscopic HDTV images
TL;DR: St stereoscopic HDTV images were displayed within the corresponding range of depth of focus, and remained still in the depth direction, and visual fatigue was almost the same as that induced by watching images displayed at the depth of the screen.
Journal Article
A Unified Formula For Light-adapted Pupil Size
Andrew B. Watson,John I. Yellott +1 more
TL;DR: A new unified formula is developed that incorporates the effects of luminance, size of the adapting field, age of the observer, and whether one or both eyes are adapted.
Peripheral refraction along the horizontal and vertical visual fields in myopia
TL;DR: Myopia has more effect on peripheral refraction of adult eyes along the horizontal than along the vertical visual field, and both peripheral myopic shifts in peripheral M and J(180) asymmetry were unaffected by magnitude of myopia.

Journal Article
Transmission of the Ocular Media
TL;DR: The spectral transmittance of ultraviolet, visible, and near infrared light through the ocular media of humans has been measured and shows that the transmission of ultraviolet radiation decreases with the age of the eye.
Journal ArticleDOI
The Luminous Efficiency of Rays Entering the Eye Pupil at Different Points
Walter Stiles,B. H. Crawford +1 more
TL;DR: In this article, a variable graduated neutral wedge is inserted at the aperture P and this enables the two halves of the photometric field to be adjusted to equality of brightness by the subject.
Journal ArticleDOI
Does Education Explain Ethnic Differences in Myopia Prevalence? A Population-Based Study of Young Adult Males in Singapore
TL;DR: There is a high prevalence of myopia in Singapore and education was strongly associated with prevalence and severity, but interethnic variation observed was not fully explained by differences in education level.
Journal ArticleDOI
The chromatic eye: a new reduced-eye model of ocular chromatic aberration in humans
TL;DR: The reduced eye was further modified by changing the refracting surface to an aspherical shape to reduce the amount of spherical aberration, providing an improved account of both the longitudinal and transverse forms of ocular chromatic aberration.
