Lewis has enjoyed a strong 2018 on the ProTour and it has enabled the former finalist to qualify for Blackpool as the 16th seed, throwing open the possibility of a last-16 showdown with Michael van Gerwen.
However, Lewis has insisted that he is not looking too far ahead as the Stoke-on-Trent thrower looks for a return to form on the big stage.
The 33-year-old told Live Darts: "James is a great player, you can't underestimate him. Everyone's already talking about me and MVG meeting in the last 16 but I can't look any further than the first round.
"If you take your eye off the ball in that round, you could be out. If you look around the room for a mug, you're the mug. I've made the semi-finals on the last two occasions there so hopefully I can go two better and win it."
Lewis heads into the tournament having won just two of his last seven matches at PDC Major tournaments.
