At 90, Salome Nyambura’s eyesight is okay. However, if you ask her, she sees things differently. In distances beyond 50 metres, people appear like gangly silhouettes pirouetting in the horizon.
“I hurt my eyes the moment I learnt to read the Bible,” she tells me, quickly adding that she has a distant ache in her back. “I would sit next to an oil lamp and read into the night. I did not know then that the poor lighting affected my eyes. Soot, too, hurt me.”
