KARACHI: Muhammad Zarnosh picks up his toolbox and reaches for his young son's hand, ready to leave home for the plumbing and electronic repairs shop where he works in an impoverished neighborhood in the Pakistani port city of Karachi. 
Zarnosh, now in his thirties, experienced gradual vision loss since birth but around ten years ago he lost his sight completely. Since then, he has had to depend on friends and family to help him move around, but that hasn’t stopped him from carrying on with his work as a repairman. 
Zarnosh learnt plumbing and electric repairs from his father as a teenager. When he became blind, he strived to continue his job even though it put him at risk
“It’s better to do work and labor to earn a livelihood for my children than to beg," he told Arab News in an interview in Karachi’s Qasba Colony area. “I am disabled but I am toiling for bread and butter. I have seen people who have no hands or legs but still do hard work. I believe that hard work is the right thing."

According to Human Rights Watch, estimates of the number of people living with disabilities in Pakistan wildly vary from 3.3 million to 27 million. Pakistan ratified the Convention on the Rights of Persons with Disabilities in 2011.
Last month, Pakistan passed a new disability law through a joint session of parliament, raising hopes that discrimination, especially in the workplace, against millions of Pakistanis could be curbed. 
While it remains to be seen how far the Pakistani state will implement the new law, Zarnosh said he was confident that despite his disability, he got the job done as well as any able-bodied repairman. Whoever called him for work once, he said, always called again. 
Speaking about the onset of blindness, Zarnosh said he initially had trouble seeing at night but then a decade ago “it also ended.”  
"Now, when I go for work, I have to take someone with me,” he said. Apart from needing someone to accompany him to work, there was also the added risk of accidental electrocution. 
"There are wires, these are burnt, they are mixed up,” Zarnosh said. “I take them out, separate them, some are cold and some hot. So many times, I got electric shocks.
“What can I do? What will I do, if not this? I have to do hard work. I haven’t learnt anything else,” he added. 
But Zarnosh said he never loses hope, despite the setbacks, or considers his ability a “difficulty”. After all, he has a family to provide for. 
“I couldn’t study. I learnt this skill. But I want my children to study, to join any office, join the army or police," he said. "The only difficulty I have is [providing for] the education of my children."
