Abstract
In this lecture, I will present some of the problems I wanted to solve during my career in Visual Optics. I was interested in a better understand of the optical properties of the human eye. This is a very simple optical system, but extraordinarily well adapted to the special requirements of our visual system. A better understanding of the optical physics properties of the eye allows to develop new technologies to improve vision in many people. This is related to another of my career's interests: to transfer the research results to practical solutions useful for the patients. In this context, I will revise the main optical properties of the eye and different experiments we developed during the last decades in my laboratory. In particular, some of them based in the use of adaptive optics to manipulate light wavefronts in the eye to correct aberrations and scatter. I will also present several recent results ranging from the nature of the lens movements, the development of new types of intraocular lenses to new opto-electronic instruments for the correction of cataracts and presbyopia.
