however if they shot from a distance outside of the critical radiation intensity for power loss to occur, targetting with telescopic vision of course, he would be able to effectively shoot/melt it. Would really do anything though even if heat vision reached sublimation heat since then it'd just be kryptonite vapour which is proven a quite effective form against Superman. The only real way that it could be effective at disposing would be to induce a small scale nuclear fusion, actually change the chemical composition of the kryptonite. Don't think heat vision has the juice for that...
