In a letter dated 29/5/19, this charity stated: “Regarding RNIB’s stance on human embryo experimentation, I can confirm that RNIB does not fund medical research. Donations go towards services for blind and partially sighted people and achieving our vision of a world without barriers for people with sight loss. As such, RNIB does not have a stance on the use of human embryos in research because it is not relevant to our work.”
