Peli Lens
The Peli Lens is a mobility aid for people with homonymous hemianopia. It is also known as “EP” or Expansion Prism concept and was developed by Dr. Eli Peli oSchepens Eye Research Institutein 1999. It expands the visual field The visual field is "that portion of space in which objects are visible at the same moment during steady fixation of the gaze in one direction"; in ophthalmology and neurology the emphasis is mostly on the structure inside the visual field and it i ... by 20 degrees. He tested this concept on several patients in his private practice with great success using 40Δ Fresnel press-on prisms (Peli 2000). Development of the lens and clinical trials were funded by NEI-NIH Grant EY014723 awarded to Chadwick Optical. The results of the multi-center clinical trials were published in 2008 reporting a 74% patient acceptance rate.Bowers A, Keeney K, Peli E.

Mobility Aid
A mobility aid is a device designed to assist individuals with impaired movement. These devices help people walk, maintain balance, or get around more easily. Mobility aids include walking supports like canes, crutches, and walkers for those with limited walking ability, as well as wheelchairs and scooters for individuals who cannot walk or need assistance over longer distances. For people who are blind or visually impaired, tools such as white canes and guide dogs offer essential support. There are also aids designed for use within buildings, such as stair lifts and transfer devices that help users move between floors or from one position to another. The term “mobility aid” generally refers to mechanical or assistive devices and is often used in official contexts, including tax or medical equipment classifications. These devices are typically intended to offer mobility similar to what a person might achieve when walking or standing without help. Emerging technologies cont ...

Homonymous Hemianopia
In linguistics, homonyms are words which are either; '' homographs''—words that mean different things, but have the same spelling (regardless of pronunciation), or '' homophones''—words that mean different things, but have the same pronunciation (regardless of spelling). Using this definition, the words ''row'' (propel with oars), ''row'' (a linear arrangement) and ''row'' (an argument) are homonyms because they are homographs (though only the first two are homophones); so are the words ''see'' (vision) and ''sea'' (body of water), because they are homophones (though not homographs). A more restrictive and technical definition requires that homonyms be simultaneously homographs ''and'' homophoneshomonym ''Random House Unabridged Dictionary'' at dictionary.com—that is, they have identical spelling ''and'' pronunciation but different mea ...

Visual Field
The visual field is "that portion of space in which objects are visible at the same moment during steady fixation of the gaze in one direction"; in ophthalmology and neurology the emphasis is mostly on the structure inside the visual field and it is then considered “the field of functional capacity obtained and recorded by means of perimetry”.Strasburger, Hans; Pöppel, Ernst (2002). Visual Field. In G. Adelman & B.H. Smith (Eds): ''Encyclopedia of Neuroscience''; 3rd edition, on CD-ROM. Elsevier Science B.V., Amsterdam, New York. However, the visual field can also be understood as a predominantly ''perceptual'' concept and its definition then becomes that of the "spatial array of visual sensations available to observation in introspectionist psychological experiments" (for example in van Doorn et al., 2013). The corresponding concept for optical instruments and image sensors is the field of view (FOV). In humans and animals, the FOV refers to the area visible when eye mov ...
