The Nystagmus Network is a registered charity in England and Wales supporting people with nystagmus, raising awareness of the condition and funding research. Nystagmus is a form of visual impairment, characterised by involuntary movements of the eyes. Focus and depth perception are compromised which means that support is required with education, employment and, often, mobility and independent living. At least 1 in 1,000 babies are born each year with nystagmus. Many more may contract acquired nystagmus later in life.
