Visual prosthesis. 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 International Agency for the Prevention of Blindness (IAPB) is a global alliance of eye health organisations working for the prevention of blindness and vision impairment. [4] IAPB was established in 1975 to work as an umbrella body for global blindness prevention activities. This agency is a partner of World Health Organization. [5][6]
Vision rehabilitation. Vision rehabilitation (often called vision rehab) is a term for a medical rehabilitation to improve vision or low vision. In other words, it is the process of restoring functional ability and improving quality of life and independence in an individual who has lost visual function through illness or injury. [1][2] Most ...
Specialty. Ophthalmology, optometry. Anterior ischemic optic neuropathy (AION) is a medical condition involving loss of vision caused by damage to the anterior portion of the optic nerve as a result of insufficient blood supply (ischemia). This form of ischemic optic neuropathy is generally categorized as two types: arteritic AION (or AAION ...
Visual or vision impairment (VI or VIP) is the partial or total inability of visual perception.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.

Photokeratitis or ultraviolet keratitis is a painful eye condition caused by exposure of insufficiently protected eyes to the ultraviolet (UV) rays from either natural (e.g. intense direct or reflected sunlight) or artificial (e.g. the electric arc during welding) sources. Photokeratitis is akin to a sunburn of the cornea and conjunctiva.
The mission of the Foundation Fighting Blindness is to fund research that will lead to the prevention, treatment and cures for the entire spectrum of retinal degenerative diseases, including retinitis pigmentosa, macular degeneration, Usher syndrome, Stargardt disease and related conditions. These diseases, which affect more than 10 million ...
A retinal implant is a visual prosthesis for restoration of sight to patients blinded by retinal degeneration. The system is meant to partially restore useful vision to those who have lost their photoreceptors due to retinal diseases such as retinitis pigmentosa (RP) or age-related macular degeneration (AMD).
