The Eye as an Optical Instrument: From Camera Obscura to Helmholtz's Perspective

  title={The Eye as an Optical Instrument: From Camera Obscura to Helmholtz's Perspective},
  author={Nicholas J. Wade and Stanley Finger},
  pages={1157 - 1177}
The era of modern vision research can be thought of as beginning in the seventeenth century with Johannes Kepler's understanding of the optics of the camera obscura with a lens and its relation to the eye. During the nineteenth century, Helmholtz used “The eye as an optical instrument” as the title for one of his Popular Lectures, and such a conception of the eye is now accepted as a fundamental feature of visual science. In analysing the optics of the eye, Helmholtz constructed some novel…

Advances in understanding the initial stages of the visual process have been made over the centuries. This heritage will be reviewed with respect to the passage of light through the eye, as well as
On the Physical Origins of Inverted Optic Images
It is demonstrated that inverted optic images (including inverted optic flow) can and do form in the absence of any biology and that sufficient conditions for inverted image formation predate the origins of life.

Philosophical instruments were designed to examine phenomena experimentally, rather than by naturalistic observation alone, and consisted of simple contrivances that manipulated time and space in ways that had not previously been appreciated.
Helmholtz at 200
Among the optical instruments Helmholtz invented were the ophthalmoscope, ophthalmometer, and telestereoscope; and mention is made of his investigations into accommodation, colour vision, eye movements, stereoscopic vision, binocular rivalry, and lustre.

In atiquity there was no differentiation between the eye, light and vision. Optics was the study of vision. Debate continued for nineteenhundred years, from Plato to Kepler, as to whether vision

The art of visual communication is not restricted to the fine arts; scientists also apply art in communicating their ideas graphically, and the development of a discipline can be traced through graphical representations, as explored here in the context of concepts of visual science.

A proposed increase in retinal field-of-view may lead to spatial shifts in images
It is demonstrated that when a monocular-like imaging system operates entirely with optically dense fluids, an increase in field-of-view (FOV) is observed compared to an experimental condition, where the ocular medium is optically neutral.
Seeing the Light: A Classroom-Sized Pinhole Camera Demonstration for Teaching Vision
We describe a classroom-sized pinhole camera demonstration (camera obscura) designed to enhance students' learning of the visual system. The demonstration consists of a suspended rear-projection
Overcoming Presbyopia by Manipulating the Eyes' Optics
An adaptive optics (AO) IOL metrology system was developed, providing an objective measure of through-focus retinal image quality and practical guidelines for patient selection and investigating the potential of higher order aberrations and pupil amplitude apodization to increase the depth of focus of the presbyopic eye.


In the Eye's Mind: Vision and the Helmholtz-Hering Controversy
These two German physicians, pioneers and giants in the fields of physiological optics and visual physiology, were founders of schools of research and teaching in Germany at a time when there was a highly competitive atmosphere setting the stage for a rapid expansion of knowledge in all scientific fields.
Light and Sight since Antiquity
Light and sight were not distinguished from one another until the dioptrics and the anatomy of the eye had been adequately described in the seventeenth century, then the problem of accommodation was exposed, and corrections for errors of refraction could be given theoretical support.

Porterfield and Wells on the Motions of Our Eyes
Both Porterfield and Wells investigated the involvement of eye movements in binocular vision and in postrotary visual motion, and both maintained that the eyes did not move following body rotation, whereas Wells, using an afterimage as stabilised retinal image, described the characteristics of postrotaries nystagmus and their dependence on head orientation.
