Norris admitted he’s had a rough year but that now he’s been practicing and wearing glasses, he feels like he’s coming back. "Determination got me through that one," said Norris, who was making his first televised appearance since February. "I've had rough year but I've been on the practice board and started wearing glasses and I feel like I'm coming back. "Simon Whitlock gave me his glasses to try and since then I can actually see again. They've made a huge difference and I hope things are on the up now." for more information about the PDC World Darts Championship, including schedules and the prize fund breakdown.
