Based on that explanation (I'm going off of that and the profiles so I may miss some manga scan that says otherwise), he seems to still be in the process making it so that's always active based on that "almost".
But let's set that aside and assume he has to be aware of any materials that contact Infinity, Boa's beams are essentially just supernatural light, which is far from something he wouldn't have accounted for.
(I'd also say that logically the fact he can see would mean he has that much precision to let light in but I admit that's largely my own conclusion rather than what's in the manga).
