"She knew of Malawi's achievement and was so pleased that this was made possible by the fund, with eyesight being its principle objective. She was so happy for Malawians."
Sophie was referring to the Queen Elizabeth Diamond Jubilee Trust Fund, which provides financial support to help combat avoidable blindness across the Commonwealth including in Malawi.

The now 18-year-old royal's eye condition compelled Countess Sophie to research blindness, a passion that led her to be named the Global Ambassador for the International Agency for the Prevention of Blindness.
She has raised awareness for several sight charities over the years, including Seeing Is Believing, blindness prevention charity Orbis UK and The Visions Foundation, which works to help people who are visually impaired.
Over one billion people live with preventable sight loss and in 2012, the Queen Elizabeth Diamond Jubilee Trust (QEDJT) was launched, with the aim to end avoidable blindness across the Commonwealth and beyond.
