Ben Ramus: Our epic challenge for Retina UK

This July, Ben Ramus will lead a group of twelve adventurers as they take on the renowned National Three Peaks Challenge, in aid of national sight loss charity, Retina UK. Ben has decided to take on the epic challenge in recognition of two of his uncles’ sight loss journey, as they live with the rare inherited sight loss condition, retinitis pigmentosa.
