The extent to which monocular visual performance of subjects with normal amounts of ocular aberrations can be improved with adaptive optics (AO) depends on both the pupil diameter and the luminance for visual testing. Here, the benefit of correction of higher order aberrations for […]

1. Introduction
The human eye is an extremely robust, and rather simple, optical instrument. It is composed of only two positive lenses, the cornea and the crystalline lens, that project images of the world into the retina initiating the visual process. Compared with artificial optical systems, often formed by many […]

Corneal small aperture inlays provide extended depth of focus as a solution to presbyopia. As this procedure is becoming more popular, it is interesting to compare its performance with traditional approaches, such as monovision. Here, binocular visual acuity […]

Binocular open-view instrument to measure aberrations and pupillary dynamics

Autores: Emmanuel Chirre, Pedro M. Prieto and Pablo Artal
Revista: Optics Letters
Volumen: Vol. 39
Paginas: pp. 4773-4775

ISBN: 0146-9592
We have designed and built a binocular Hartmann–Shack wave-front sensor using a single microlens array and camerafor real-time aberration measurement of both eyes in an open-view configuration. Furthermore, the use of a longwavelength (1050 nm) laser diode makes the illumination source completely invisible, so […]
