How your fundraising helps
Every day, 250 people in the UK start to lose their sight. Many people won't get any practical or emotional support when they need it most. We want to change that.
It costs just £250 for someone with sight loss to attend an RNIB Living Well with Sight Loss course which help attendees increase independence, boost confidence and connect with others to share experiences.
Your fundraising will help ensure that no one faces sight loss alone.
