What is Binocular Vision? A creature with two eyes that are used together to view a single image is said to have binocular vision. Creatures with binocular vision have many advantages over creatures with only a single eye or creatures who are not able to use their multiple eyes together. At a very simple level, a second eye provides a safe level of redundancy; if one eye is lost, another is still there, allowing the creature to see.

Binasal Occlusion After a head injury, stroke or brain tumor visual pathways in the brain can be disturbed. Disruption of nerve fibers in the brainstem can adversely affect the balance system and orientation systems. Walking in unfamiliar environments or crowded areas, like malls, can be overwhelming. The purpose of the binasal occlusion is to help with spatial orientation. Many patients have benefited from this treatment.

- Double vision, also known as diplopia, occurs when you see objects duplicated in your vision rather than a single clear representation of each object. Double vision may be temporary or permanent.

- Objects within the binocular visual field are visible to each eye, albeit from different angles. The monocular visual field (Figure 14.1) is determined with one eye covered. The area of overlap of the visual field of one eye with that of the opposite eye is called the binocular field (Figure 14.2). All areas of the binocular visual field are “seen” by both eyes.

Color vision Color vision is the ability of an organism or machine to distinguish objects based on the wavelengths (or frequencies) of the light they reflect, emit, or transmit.

Our Readers Want to Know: What Is the Difference Between Low Vision and Legal Blindness? Part 2 of the U.S. definition of legal blindness states this about visual field 1  : OR a visual field (the total area an individual can see without moving the eyes from side to side) of 20 degrees or less (also called tunnel vision) in the better-seeing eye.

Ocular dominance Dominant eye in vision. Ocular dominance, sometimes called eye dominance or eyedness, is the tendency to prefer visual input from one eye to the other. It is somewhat analogous to the laterality of right or left handedness, however the side of the dominant eye and the dominant hand do not always match. In normal binocular vision there is an effect of parallax, and therefore the dominant eye is the one that is primarily relied on for precise positional information. This may be especially important in sports which require aim, such as archery, darts or shooting sports.

depth perception depth perception. the ability to judge depth or the relative distance of objects in space and to orient one's position in relation to them. Binocular vision is essential to this ability. Also called stereopsis. depth per·cep·tion.

Sudden onset of binocular diplopia Sudden onset of binocular diplopia: Introduction. Sudden onset of binocular diplopia: Sudden onset of binocular diplopia is the rapid development of double vision because the eyes do not align properly. See detailed information below for a list of 3 causes of Sudden onset of binocular diplopia, including diseases and drug side effect causes. Causes of Sudden onset of binocular diplopia:

- Double vision, also known as Diplopia, is the simultaneous perception of two images of a single object-the patient sees two images of a single thing either all the time, or some of the time. The displacement may be horizontally, vertically or diagonally.ouble vision, which is sometimes confused with blurred vision, as mentioned above, is when the individual sees two images of a single object. Blurred vision is a single unclear image, while double vision is the perception of two images, when there is only one. Double vision affects people in different ways.

- What Is Perfect Vision? In cases of normal vision, also called perfect vision or 20/20 vision, the eye is able to focus light from objects precisely on the retina at the back of the eye. Refractive errors occur when the eye is unable to properly focus light on the retina.

Astigmatism A refractive error is an eyesight problem. Refractive errors are a common reason for reduced level of eyesight (visual acuity). Refraction refers to the bending of light, in this case by the eye, in order to focus it. A refractive error means that the eye cannot focus light on to the retina properly. This usually occurs either due to abnormalities in the shape of the eyeball, or because age has affected the workings of the focusing parts of the eye. There are four types of refractive error: Short sight (myopia).

Binocular Vision The advantages of a Binocular vision are: The first and the foremost advantage of a binocular vision is single vision. In addition to single vision it results in stereopsis – the most precise kind of depth perception. Enlargement of the field of vision. Compensation for blind spot and other differences.

- A lens that has one focal power, usually a correction for nearsightedness, farsightedness, and/or astigmatism. What is bifocal? In addition to a correction for nearsightedness, farsightedness, and/or astigmatism, a bifocal contains an addition for near vision.

What Is Depth Perception and How Important Is It? Depth Perception is also known as stereopsis. People with normal binocular vision (vision created by two separate eyes working together to form a single image) can perceive the depth and distance of objects.

Visual acuity Visual acuity is typically measured while fixating, i.e. as a measure of central (or foveal) vision, for the reason that it is highest there. However, acuity in peripheral vision can be of equal (or sometimes higher) importance in everyday life.

What is Binocular Vision? Dogs and coyotes have good binocular vision, because their eyes are more close together. This is good for them, because in the wild, they have to be able to see the distance between themselves and the rabbits, birds, or other creatures with eyes on the sides of their heads.

achromatic vision 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. achromatic vision monochromatic vision.

Psychology a binocular cue for perceiving depth; by comparing images from the two eyeballs, the brain computes distance-the greater the disparity (difference) between the two images, the close the object. - The slight difference in the two retinal images due to the angle from which each eye views an object.

Binocular disparity Binocular disparity refers to the difference in image location of an object seen by the left and right eyes, resulting from the eyes’ horizontal separation (parallax). The brain uses binocular disparity to extract depth information from the two-dimensional retinal images in stereopsis.

- All animals have binocular vision, meaning that they see with two eyes, but the brain combines the signals from both eyes into one image. Binocular vision helps make up for the blind spot caused by the optic disc. The overlap of the visual fields fills in the gaps.
