Definitions



A person with low vision is one who has an
impairment of visual function for whom full
remediation is not possible by conventional
spectacles, contact lenses or medical
intervention and which causes restriction in
that person's everyday life.
A low vision service is a rehabilitative or
habilitative process, which provides a range of
services for people with low vision to enable
them to make use of their eyesight to achieve
maximum potential.
