Fixation light hue bias revisited: Implications for using adaptive optics to study color vision

Current vision science adaptive optics systems use near infrared wavefront sensor 'beacons' that appear as red spots in the visual field. Colored fixation targets are known to influence the perceived color of macroscopic visual stimuli (Jameson, D., & Hurvich, L. M. (1967). Fixation-light bias: An unwanted by-product of fixation control. Vision Research, 7, 805-809.), suggesting that the wavefr...

Color Vision: Mice See Hue Too

A transgenic mouse has been generated with three cone types, instead of the normal murine two. Remarkably, some of these mice use the extra cone to make trichromatic color discriminations similar to those that are the basis of human color vision.

Adaptive optics for peripheral vision

Understanding peripheral optical errors and their impact on vision is important for various applications, e.g. research on myopia development and optical correction of patients with central visual field loss. In this study, we investigated whether correction of higher order aberrations with adaptive optics (AO) improve resolution beyond what is achieved with best peripheral refractive correctio...

Applications of Adaptive Optics for Vision Science

There are a number of applications of adaptive optics for basic research in vision science, as it is now possible to study microstructures in the living human retina which could not be done before. One of the biggest merits provided by adaptive optics is that it is non-invasive. In this chapter, we describe the applications of an adaptive optics system for vision research, not only for basic sc...
