Towers said: "Sometimes people think 'well he's got a guide dog so he can just get on with it', but in actual fact, if you're walking down a street and you hear a loud noise and you can't see what actually happened, it can be quite nerve racking"
"I always live in hope that one day they'll find a cure for myself, but for the moment it's just appreciating what I do have"
Chris suffers from Rod-Cone Dystrophy, a disease with a 1 in 40,000 prevalence, which pertains a group of inherited eye disorders that affect the light sensitive cells of the retina called the cones and rods.
"From a very young age I wasn't able to see in the dark because the rods in my eyes had died away
"As a 5-year-old, you don't really realise, you just think its normal life.
"But as I got into my thirties my cones started to deteriorate as well.
"I can see you right now, but its kind of like a silhouette and I get quite a lot of flashing lights in my eyes.
"It's sort of like looking into the fog"
