Cohen was diagnosed with Retinitis Pigmentosa, a genetic disorder of the eyes that causes loss of vision. Cohen had bad eyesight in his childhood, but was able to get by using aids. However, his eyesight has declined since then. In the final year of his PhD program, Cohen started to have trouble reading books. In his 50s, Cohen became legally blind.[citation needed]

Cohen also created a Dangerous Vision website[7] to share his experience with vision loss more widely.
