The 30-year-old from Trinidad and Tobago is in Dunedin to cover the New Zealand-West Indies test with the help of his wife, Gale Browne-Tyson, for the Family Focus Broadcasting Network (FFBN).
Mr Tyson was born with a condition called keratoconus.
He can make out only outlines and shapes.
But the avid sports fan refuses to let his impairment get in the way of his passion.
He fell in love with cricket and football as a youngster, tuning in to the radio and listening to broadcasts.
"Even when I was still at school, I would go home and listen to games in Australia and New Zealand late into the night," he said.
"My mother would get upset because I had to go to school the next day.
But cricket became my life and it was more important sometimes than exams.
"I remember sitting at home in the '80s when I was 9 or 10 and working out the average for Viv Richards . . .
I just love the game. Sports is just my thing."
He began working for FFBN in 2002 and it was there he was able to put his passion into practice.
"Every time I went on air, I spoke about sport.
So, eventually, I said this is my passion and I need to get into writing about sport and become a sports analyst."
Of course, Mr Tyson faces a unique challenge in that he cannot see the action.
But his passion for cricket, a healthy imagination and an extraordinary memory compensate for his lack of vision.
To get the information for his regular reports, Mr Tyson listens to commentary, talks to the other journalists about the game and questions players and coaches in press conferences.
This is his first tour and he said it would not be possible without the help of his wife.
"She is the reason why I'm here.
I just feel God placed her in my life for a particular purpose: to allow my dreams to come true and to fulfil my dreams."
