Accessory Structures of the Eye01:17

Accessory Structures of the Eye

4.3K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Vision01:24

Vision

61.2K
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.

Muscles of the Eye01:20

Muscles of the Eye

5.3K
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and...

Visual System01:26

Visual System

2.2K
Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

2.5K
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.

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

7.1K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Area of Science:

  • Neuroscience
  • Vision Science
  • Cognitive Psychology

Background:

  • The primate visual system features a central fovea for high acuity, necessitating eye movements for repositioning.
  • Previous research often focused on foveal vision during fixation and the negative aspects of eye movements, like saccadic suppression.

Purpose of the Study:

  • To compare human visual perception with and without saccadic and smooth pursuit eye movements.
  • To emphasize the diverse functions and optimized roles of eye movements in visual perception.

Main Methods:

  • Review comparing visual perception during fixation versus during active eye movements (saccades and smooth pursuit).

Main Results:

  • Eye movements are not solely for foveal acuity but are integral to active information sampling across the visual field.
  • The interaction between eye movements and visual perception is optimized for calibrating visual input.

Conclusions:

  • Eye movements and visual information uptake are intricately linked, enabling a more complete perception of the world.
  • Studying perception solely during fixation overlooks the critical contributions of eye movements.
