This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The eye is an optical instrument that projects scenes of the visual world onto the retina. However the human eye is far from being a perfect optical system, and, as a consequence, the images projected on the retina are blurred by ocular aberrations, as well as diffraction and scattering. Therefore in the last years, multiple technologies based on wavefront sensing and Adaptive Optics (AO) have been developed for the measurement and correction of ocular aberrations. As a result important knowledge has been gained on the contribution of the different components of the eye to the degradation of image quality. However the processes underlying neural adaptation to ocular aberrations are not yet well understood. Understanding the effects of a particular low order aberration, astigmatism, is particularly attractive to investigate adaptive processes in the visual system due to the inherent oriented nature of the blur that it produces. Typically, the impact of ocular aberrations on vision is studied using wavefront sensors with monochromatic, generally infrared, light. However, the retinal image quality is degraded by the presence of both monochromatic and polychromatic aberrations in the ocular optics. The study of the impact of retinal image quality on vision should therefore consider both the aberrations in the visible light, as well as the effect of chromatic aberrations. In addition optical and structural properties of the eye change with age and with certain ocular conditions and treatments, altering the natural aberrations, as well as the interactions between monochromatic and chromatic aberrations, and consequently the visual function. xvi Summary of the thesis The understanding of the interactions of these aberrations and their effect upon correction is essential to explore the limits of human spatial vision, and to design and optimize new alternatives of correction of Presbyopia/Myopia and more complex individualized refractive corrections. In this thesis we have used AO techniques to study the effect of specific monochromatic aberrations and their combinations on vision, to test neural adaptation to those aberrations and their correction, to measure chromatic aberrations of the eye in normal and pseudophakic eyes, and to test vision with simulated multifocal solutions for Presbyopia...

Download or read book Optics of the Human Eye written by David A. Atchison and published by CRC Press. This book was released on 2023-03-31 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the optical structure and optical properties of the human eye. For ease of reference, the most commonly useful topics are at the beginning and topics with narrower appeal are placed towards the end. The book is divided into five sections, covering: Basic optical structure of the eye, including the refracting components, the pupil, axes, and simple models of the eye Image formation and refraction of the eye, including refractive errors, measurement, and correction Interactions between light and the eye, considering transmission, reflection, and scatter in the media and at the fundus Aberrations and retinal image quality Depth-of-field and age-related changes in the optics of the eye There have been many developments in the field of visual optics since the first edition was published in 2000. There have been advances in instrumentation for imagery, biometry, and aberrations of the eye. The refraction anomaly of myopia has increased in prevalence throughout the world, and is getting increasing attention because of its association with ocular pathology in the middle and later years of life. Ocular aberrations are now considered in terms of Zernike polynomials rather than Taylor polynomials. Aberrations can be manipulated to better understand their effects on visual performance to improve imagery of the retina for the betterment of diagnosis of various ocular conditions, and to treat the progression of myopia in children. To deal with these developments, the section on aberrations and retinal image quality has undergone considerable revision. This book will be an invaluable purchase for all those with an interest in vision, such as optometrists, ophthalmologists, vision scientists, optical physics, and student of visual optics. An understanding of the optics of the human eye is particular important to designers of ophthalmic diagnostic equipment and visual optical systems such as telescopes.

Available in PDF, EPUB and Kindle. Book excerpt: An important part of the information that we receive from the world is through the sense of vision: the eye projects images on the retina, which transforms them into nerve impulses that reach the neuronal cortex, where these impulses are interpreted. However, the images projected onto the retina are not perfect, as they are affected by diffraction, scattering, and aberrations, which degrade contrast and decrease the resolution limit of the eye.To understand the effect of aberrations on vision, it is necessary to develop technologies and experiments that allow objectively and subjectively assess their interaction. In this sense, Adaptive Optics (AO) has played an important role in increasing our knowledge about the neural processes of vision, since AO can be used to measure, correct and induce aberrations. Understanding what role aberrations play and what their impact is on vision will help to develop better correction designs for the eye...
