The Metropolitan Society for the Blind has changed its name to BlindAid.
The charity, which provides a range of services for blind people, has carried out the rebrand because the organisation is not widely recognised, according to a spokesman.
BlindAid will shortly launch a new website and new publicity materials.
"The charity’s former name did not encapsulate that the organisation is a service provider," the spokesman said. "The aim of the rebrand is to raise the profile of the charity and increase fundraising."
BlindAid provides services for about 1,500 people in inner London, including home visits for more than 500 people, telephone support and information and advice at several hospitals.
The charity also provides small grants to assist with aids and adaptations, communications equipment and domestic appliances.
The spokesman said the charity’s services would not change as a result of the rebrand. He said no one from the charity was available to confirm how much the rebrand cost.
