A sight loss charity that has operated for 168 years said it was "devastated" after failing to raise enough money to secure its long-term future.
Vista, which offers lifelong support to people with sight loss in Leicester, Leicestershire and Rutland, launched a campaign in February to raise £2m to tackle financial difficulties.
The charity said a third of its work, which is a statutory requirement, will now be transferred to another organisation while it "explores options" to safeguard other services.
Steve Payne, director of care and services at Vista, said the charity's financial situation was "very fragile".
When launching the campaign, Vista said the money was needed to cope with "rising costs and increasing demand".
However, despite the "remarkable efforts" of its donors, the charity said it would not be able to continue in its current form.
Jayne, from Sileby, said her 10-year-old daughter, Grace, has been helped by Vista ever since she was diagnosed with sight loss.
"We're a little bit worried because of the unknown," she said.
"The NHS is great and we have services there. The education authority is pretty good but everybody's stretched, so you can be waiting for a long time.
"Vista used to bridge that gap, so it's all a bit concerning.
"Vista have tried really hard and I feel for them as well. We just want them to never give up the fight."
The charity confirmed a third of its work, including running a sight loss register, providing support to people who have been recently diagnosed and cane training, will be transferred to BID Services, a Birmingham-based charity which helps people with hearing and sight loss.
However its other non-statutory services are under threat.
These include services for children and young people, such as peer-to-peer meet ups and activities, as well as family inclusion events, where relatives of the visually impaired can take part.
Tech support, community meet-ups and three charity shops are also under threat.
"We're absolutely devastated," said Steve Payne.
"We had an amazing response from the public for our appeal, but sadly we were not able to meet the targets we wanted.
"Our financial situation is very fragile, I don't want to give any illusion that it's not.
"I think it would be fair for me to say it's too early to say what could happen with Vista moving forward.
"We are working really hard in the background to see what we can secure either as Vista or with partners that want to join in and support us with that.
"I don't want to make promises, but I'm pretty sure there will be something left for people."
Vista said the transfer of services to BID would take place on 6 May.
