The Human Balance System Balance is achieved and maintained by a complex set of sensorimotor control systems that include sensory input from vision (sight), proprioception (touch), and the vestibular system (motion, equilibrium, spatial orientation); integration of that sensory input; and motor output to the eye and body muscles.

Retinal Disparity The images overlap in the center, and the brain connects these together into one seamless view. Thus, Retinal Disparity is the difference between the visual images that each eye perceives because of the different angles in which each eye views the world. Retinal disparity is important for depth perception.

vision Top, Anatomy of the eye. Vision is the reception of images by the eye as a result of the passage of light into the eye. Light is focused by the lens on the retina, where it is converted into nerve impulses that are transmitted to the centers in the brain where images are interpreted.

Miosis Definition (MSH) The dioptric adjustment of the EYE (to attain maximal sharpness of retinal imagery for an object of regard) referring to the ability, to the mechanism, or to the process. Ocular accommodation is the effecting of refractive changes by changes in the shape of the CRYSTALLINE LENS.

- Low vision is a term often used interchangeably with visual impairment and refers to a loss of vision that may be severe enough to hinder an individual's ability to complete daily activities such as reading, cooking, or walking outside safely, while still retaining some degree of useable vision.

RenÃ© Descartes The three components of the vision system are the object being viewed, the light, and the eye. When light strikes an object, a portion of the visible spectrum may be absorbed by the molecules comprising the object. Some portion that is not absorbed reflects off the object and strikes the

Our Readers Want to Know: What Is the Difference Between Low Vision and Legal Blindness? Visual Acuity and Low Vision. Visual acuity is a number that indicates the sharpness or clarity of vision. A visual acuity measurement of 20/70 means that a person with 20/70 vision who is 20 feet from an eye chart sees what a person with unimpaired (or 20/20) vision can see from 70 feet away.

Visual perception See also: Visual system. Visual perception is the ability to interpret the surrounding environment using light in the visible spectrum reflected by the objects in the environment. The resulting perception is also known as visual perception, eyesight, sight, or vision (adjectival form: visual, optical, or ocular).

Balance (ability) In biomechanics, balance is an ability to maintain the line of gravity of a body within the base of support with minimal postural sway. Sway is the horizontal movement of the centre of gravity even when a person is standing still. A certain amount of sway is essential and inevitable due to small perturbations within the body or from external triggers. An increase in sway is not necessarily an indicator of dysfunctional balance so much as it is an indicator of decreased sensorimotor control. Main

Exotropia When both eyes are properly aligned and aimed at the same target, the visual portion of the brain fuses the forms into a single image. When one eye turns inward, outward, upward, or downward, two different pictures are sent to the brain. This causes loss of depth perception and binocular vision.

Eye convergence The object of convergence is the directing of the yellow spot in each eye towards the same point, so as to produce singleness of vision; diplopia, or double vision, at once resulting when the image of an object is formed on parts of the retina which do not exactly. correspond in the two eyes.

""" Why am I having trouble focusing my eyes? """ Problems with your vision can often cause headaches and poor balance. Diseases affecting vision can arise from the eye, the part of the brain that interprets visual stimuli, or the nerve fibers that transfer information from the retina to the brain.

Binocular vision Binocular vision is vision in which creatures having two eyes use them together. The word binocular comes from two Latin roots, bini for double, and oculus for eye. According to Fahle (1987), having two eyes confers six advantages over having one. It gives a creature a spare eye in case one is damaged.

What is Visual Perception? - Definition & Theory There is a reason why this occurs, and that is what we will look at in this lesson. Visual perception is the ability to see, organize, and interpret one's environment. In the example above, your eyes 'took in' the lines as well as the points on the ends of the lines. At the same time, your brain was organizing and making sense of the image.

Sense of balance The balance system works with the visual and skeletal systems (the muscles and joints and their sensors) to maintain orientation or balance. For example, visual signals are sent to the brain about the body's position in relation to its surroundings.

- Visual perception is a function of our eyes and brain. We see images as a whole rather then in parts. However, images can be broken down into their visual elements: line, shape, texture, and color. These elements are to images as grammar is to language. Together they allow our eyes to see images and our brain to recognize them.
