Following their marriage in 1976, Sargy Mann and Frances Carrey moved to Peckham Rye, where they remained until 1990 when they moved to Suffolk. This was a time of significant change in Sargy's life, both from a professional and a personal point of view. The family had to survive on only the salary earned by Sargy for three days of work per week at Camberwell College of Arts, and at the same time Sargy's sight started to deteriorate considerably. For ten years, Sargy had no solo exhibitions - until 1987 when he met Christopher Burness and first showed at Cadogan Contemporary.

From the late 1970's, Sargy's experimenting with light and colour continued and his style gradually matured and asserted itself. His subjects went from Lemmons and its surrounding to Peckham Rye and family life. As Sargy's sight started to decline, he continued to pursue his study of the limits of light an colour perception.

"My paintings don't reflect in a straightforward way how I was seeing; people looking at my paintings always think that I was seeing far more than was the case. Seeing is subjective, you see in your brain, and I always saw at my best when I was painting."

- Sargy Mann, in 'Sargy Mann: Probably the Best Blind Painter in Peckham', 2008
