eSight is a wearable medical device designed to improve the functional vision of those living with low vision or legal blindness. The device was developed by Canadian-based company eSight Corp.
eSight was founded in 2006 by Conrad Lewis, a Canadian electrical engineer with two legally blind sisters. His motivation was to build a device that would enable his sisters to see, be able to work and independently perform virtually all activities of daily living (ADLs). [1] [2]
The first generation of the device, eSight 1, was released in October. The second generation, eSight 2, was released in May 2015 and contained several hardware upgrades, including HD OLED screens, enhanced color and screen resolution and a longer battery life. [3]
The eSight 3 was released in February 2017. [4] [5] [6] In May 2017, Time magazine included eSight on its list of “The Best Tech of 2017 So Far.” [7]
The current generation, eSight 4 was released in early 2020.
eSight includes two HD color displays, one in front of each eye, with prescription lenses tailored to the user's particular prescription. The displays integrate dual independent, and high contrast OLED screens, 1024x768 resolution and a 37.5 degree field-of-view. The camera on the front of the device captures video in Ultra HD at 21.5 MP and allows for up to 24x zoom. eSight's user interface also features HDMI and USB inputs, Bluetooth, Wi-Fi and removable SD cards.

Geordi La Forge is a fictional character who appeared in all seven seasons of the American science fiction television series Star Trek: The Next Generation and its four feature films as well as the third season of Star Trek: Picard. Portrayed by LeVar Burton, he served as helmsman of the USS Enterprise-D in the first season of The Next Generation, then occupied the role of the chief engineer for the rest of the series and in the films before appearing as a commodore in Picard. La Forge has been blind since his birth and uses technological devices that allow him to see – a VISOR in the series and the first film, replaced by ocular prosthetic implants in the last three films and in Picard.
Glasses, also known as eyeglasses or spectacles, are vision eyewear with clear or tinted lenses mounted in a frame that holds them in front of a person's eyes, typically utilizing a bridge over the nose and hinged arms, known as temples or temple pieces, that rest over the ears.
A head-mounted display (HMD) is a display device, worn on the head or as part of a helmet, that has a small display optic in front of one or each eye. An HMD has many uses including gaming, aviation, engineering, and medicine. Virtual reality headsets are HMDs combined with IMUs. There is also an optical head-mounted display (OHMD), which is a wearable display that can reflect projected images and allows a user to see through it.
An active shutter 3D system is a technique of displaying stereoscopic 3D images. It works by only presenting the image intended for the left eye while blocking the right eye's view, then presenting the right-eye image while blocking the left eye, and repeating this so rapidly that the interruptions do not interfere with the perceived fusion of the two images into a single 3D image.
Visual or vision impairment is the partial or total inability of visual perception. For the former and latter case, the terms low vision and blindness respectively are often used. In the absence of treatment such as corrective eyewear, assistive devices, and medical treatment – visual impairment may cause the individual difficulties with normal daily tasks including reading and walking. In addition to the various permanent conditions, fleeting temporary vision impairment, amaurosis fugax, may occur, and may indicate serious medical problems.
A virtual retinal display (VRD), also known as a retinal scan display (RSD) or retinal projector (RP), is a display technology that draws a raster display directly onto the retina of the eye.
The CNIB Foundation is a Canadian charitable organization and volunteer agency dedicated to assisting Canadians who are blind or living with vision loss, and to provide information about vision health for all Canadians. Founded in 1918 as the Canadian National Institute for the Blind to assist soldiers who had been blinded in the First World War, CNIB originally offered sheltered care and specialized employment to people with vision loss. It has since expanded to include other programs and services, including research, public education, rehabilitation counselling and training, advocacy and an alternative-format library for people living with a print disability. It is a member of the Braille Authority of North America.
JORDY or Joint Optical Reflective Display is an optical viewing device developed based on NASA technology. It is used to help the visually impaired see and read.
A visual prosthesis, often referred to as a bionic eye, is an experimental visual device intended to restore functional vision in those with partial or total blindness. Many devices have been developed, usually modeled on the cochlear implant or bionic ear devices, a type of neural prosthesis in use since the mid-1980s. The idea of using electrical current to provide sight dates back to the 18th century, discussed by Benjamin Franklin, Tiberius Cavallo, and Charles LeRoy.
Braille technology is assistive technology which allows blind or visually impaired people to read, write, or manipulate braille electronically. This technology allows users to do common tasks such as writing, browsing the Internet, typing in Braille and printing in text, engaging in chat, downloading files and music, using electronic mail, burning music, and reading documents. It also allows blind or visually impaired students to complete all assignments in school as the rest of their sighted classmates and allows them to take courses online. It enables professionals to do their jobs and teachers to lecture using hardware and software applications. The advances in Braille technology are meaningful because blind people can access more texts, books, and libraries, and it also facilitates the printing of Braille texts.
The Braille Institute of America (BIA) is a nonprofit organization with headquarters in Los Angeles providing programs, seminars and one-on-one instruction for the visually impaired community in Southern California. Funded almost entirely by private donations, all of the institute's services are provided completely free of charge. The organization has seven regional centers: Anaheim, Coachella Valley, Laguna Hills, Los Angeles, Riverside, San Diego and Santa Barbara, as well as outreach programs at more than 200 locations throughout Southern California. It is a member of the Braille Authority of North America.
The Retina display is a branded series of IPS LCD and OLED displays by Apple Inc. and have a higher pixel density than its traditional displays. Apple has registered the term "Retina" as a trademark with regard to computers and mobile devices with the United States Patent and Trademark Office and Canadian Intellectual Property Office. The applications were approved in 2012 and 2014 respectively. The Canadian application cited a 2010 application in Jamaica.
