A GREAT grandfather is taking on a 107-mile charity walk – despite only having tunnel vision.

Bob Cornwall, from Haverhill, who has glaucoma, is breaking in his walking boots with a three-mile jaunt every day in preparation for the trek.

The grandfather-of-six was inspired by the death of his wife of 59 years Betty, 78, in January and hopes to raise hundreds of pounds for the International Glaucoma Association when he sets off on his mission on July 14.

Mr Cornwall’s journey will take him along the Devon and Dorset coast from Bournemouth to Torquay stopping off at bed and breakfasts along the way for some well-deserved rest.

He has enlarged sections of maps so he can read them with a magnifying glass and check he is still on track.

The 81-year-old, who has three daughters and nine great-grandchildren, said: “Betty always told me to go for it with everything and now I am.”

His quest is being supported by Sensing Change, one of just seven pilot projects in the UK which supports people with sensory loss. The group estimate that there are more than 4,000 people who are registered with sight loss in Suffolk.
