Averted vision is a technique for viewing faint objects which uses peripheral vision.
In biology, binocular vision is a type of vision in which an animal having two eyes is able to perceive a single three-dimensional image of its surroundings.
Bitemporal hemianopsia, also known as bitemporal heteronymous hemianopsia or bitemporal hemianopia, is the medical description of a type of partial blindness where vision is missing in the outer half of both the right and left visual field.
Christmas is an annual festival commemorating the birth of Jesus Christ,Martindale, Cyril Charles.
The Christmas season, also called the festive season, or the holiday season (mainly in the U.S. and Canada; often simply called the holidays),, is an annually recurring period recognized in many Western and Western-influenced countries that is generally considered to run from late November to early January.
Christmas Eve is the evening or entire day before Christmas Day, the festival commemorating the birth of Jesus.
Christmas traditions vary from country to country.
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.
Cone cells, or cones, are one of three types of photoreceptor cells in the retina of mammalian eyes (e.g. the human eye).
Cortical magnification describes how many neurons in an area of the visual cortex are 'responsible' for processing a stimulus of a given size, as a function of visual field location.
Depth perception is the visual ability to perceive the world in three dimensions (3D) and the distance of an object.
Eye movement includes the voluntary or involuntary movement of the eyes, helping in acquiring, fixating and tracking visual stimuli.
Eye movement in music reading is the scanning of a musical score by a musician's eyes.
The flicker fusion threshold (or flicker fusion rate) is a concept in the psychophysics of vision.
The fovea centralis is a small, central pit composed of closely packed cones in the eye.
The foveal system of the human eye is the only part of the retina that permits 100% visual acuity.
Fundus photography involves capturing a photograph of the back of the eye i.e. fundus.
A ganglion is a nerve cell cluster or a group of nerve cell bodies located in the autonomic nervous system and sensory system.
In critical theory, sociology, and psychoanalysis, the gaze (translated from French le regard) is the act of seeing and being seen.
Gestalt psychology or gestaltism (from Gestalt "shape, form") is a philosophy of mind of the Berlin School of experimental psychology.
Glaucoma is a group of eye diseases which result in damage to the optic nerve and vision loss.
Humans (taxonomically Homo sapiens) are the only extant members of the subtribe Hominina.
Juggling is a physical skill, performed by a juggler, involving the manipulation of objects for recreation, entertainment, art or sport.
Macular degeneration, also known as age-related macular degeneration (AMD or ARMD), is a medical condition which may result in blurred or no vision in the center of the visual field.
Magnocellular cells, also called M-cells, are neurons located within the Adina magnocellular layer of the lateral geniculate nucleus of the thalamus.
New Year is the time or day at which a new calendar year begins and the calendar's year count increments by one.
New Year's Day, also called simply New Year's or New Year, is observed on January 1, the first day of the year on the modern Gregorian calendar as well as the Julian calendar.
In the Gregorian calendar, New Year's Eve (also known as Old Year's Day or Saint Sylvester's Day in many countries), the last day of the year, is on 31 December which is the seventh day of Christmastide.
Ophthalmology is a branch of medicine and surgery (both methods are used) that deals with the anatomy, physiology and diseases of the eyeball and orbit.
Ophthalmoscopy, also called funduscopy, is a test that allows a health professional to see inside the fundus of the eye and other structures using an ophthalmoscope (or funduscope).
Optometry is a health care profession which involves examining the eyes and applicable visual systems for defects or abnormalities as well as the medical diagnosis and management of eye disease.
Parafovea or the parafoveal belt is a region in the retina that circumscribes the fovea and is part of the macula lutea.
Peter Wiedemann (born 23 October 1953 in Erlangen, West Germany) is a German ophthalmologist, specialist in medical and surgical retina and head at the Department of Ophthalmology at the Leipzig University, Germany, since 1993.
Physiology is the scientific study of normal mechanisms, and their interactions, which work within a living system.
The retina is the innermost, light-sensitive "coat", or layer, of shell tissue of the eye of most vertebrates and some molluscs.
Rod cells are photoreceptor cells in the retina of the eye that can function in less intense light than the other type of visual photoreceptor, cone cells.
A scotoma (Greek σκότος/skótos, darkness; plural: scotomas or scotomata) is an area of partial alteration in the field of vision consisting of a partially diminished or entirely degenerated visual acuity that is surrounded by a field of normal – or relatively well-preserved – vision.
Tunnel vision (also known as "Kalnienk vision") is the loss of peripheral vision with retention of central vision, resulting in a constricted circular tunnel-like field of vision.
Vision science is the scientific study of vision.
Visual acuity (VA) commonly refers to the clarity of vision.
The visual cortex of the brain is a part of the cerebral cortex that processes visual information.
The visual field is the "spatial array of visual sensations available to observation in introspectionist psychological experiments".
Visual perception is the ability to interpret the surrounding environment using light in the visible spectrum reflected by the objects in the environment.
The visual system is the part of the central nervous system which gives organisms the ability to process visual detail, as well as enabling the formation of several non-image photo response functions.
