Vision

Vision

Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Anatomy of the Eyeball

Anatomy of the Eyeball

The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...

Photoreceptors and Visual Pathways

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...

Depth Perception and Spatial Vision

Depth Perception and Spatial Vision

Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Color Vision

Color Vision

Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

Cognitive Development During Adulthood

Cognitive Development During Adulthood

Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Area of Science:

Vision science
Psychophysics
Neuroscience

Background:

Dynamic vision is crucial for daily activities.
Age-related visual decline affects contrast sensitivity and motion perception.
Form-from-motion perception, relying on motion contrast, is less understood in aging populations.

Purpose of the Study:

To assess age-related changes in dynamic vision using a novel form-from-motion test.
To quantify the decline in motion contrast sensitivity across different age groups.
To explore the potential of this test for diagnostic applications.

Main Methods:

A computerized dynamic vision test using a form-from-motion stimulus (Landolt rings in a random-dot display) was administered to 1006 healthy subjects (20-85 years).
Motion contrast was manipulated by varying the percentage of moving dots within the stimulus.
Subjects identified the gap location of the rings, reporting performance across various motion contrast levels.

Main Results:

A consistent, gradual decline in dynamic vision performance was observed with increasing age across all motion contrast levels.
Nearly half of the subjects over 70 years old performed at chance level.
The decline was evident even at higher motion contrast levels, suggesting a broad impact of aging on this visual function.

Conclusions:

Dynamic vision, specifically form-from-motion perception, significantly deteriorates with age.
The developed computerized test effectively captures age-related visual decline.
This test shows promise for screening conditions like glaucoma, visual disturbances in brain-damaged patients, and assessing visual capabilities in drivers and athletes.
