I was born with eye disease. At school I even couldn't read the blackboard. By the time I got to university, I couldn't really see images(图像) at all. I just can tell the difference between light and dark. In the first year of my PHD, I was almost 100% blind.
When I was young I used to get very angry if I encountered something I found difficult or couldn't do because of my eyes. But over time I learned that wasn't a helpful response. There's no point getting wound up by the fact that I can't see, because it won't change it.
I started climbing when I was young. My dad took me up my first rock route(路线) when I was two. All my early climbing was outdoor traditional climbing. My dad had been in the Mountain Rescue and was part of Mountaineering Club, so we would go for weekends away climbing throughout the UK.
He taught me everything I know and I led my first route outside when I was 11. At this time I could just about see well enough to place rock gear(齿轮), but not well enough to pick out the routes from the ground. People are usually amazed when they discover that not only do I climb, but I also lead climbs.
At university I joined the Mountaineering Club and was able to climb much more frequently. We had regular trips to indoor walls and weekends away outdoors. I developed a great circle of climbing friends and went on multiple trips to Europe. On these I started Alpine climbing and ice climbing too.
There was a time when I thought I might have to give up leading as my eyesight got worse. But I never thought I would stop climbing. I just learnt to adapt myself to the eye disease with the support of my friends. It's quite possible that I wouldn't be as good a climber if I weren't blind—if I didn't have these challenges. That concentration and determination is built through my disability.
