I just bought a Minox 8x25 macroscope and I found it was Argon filled. are there other benefits with argon?

According to Minox, "Due to its larger molecules, argon gas has a slower rate of diffusion than the conventional nitrogen, which guarantees that the super gas remains inside the binoculars for much longer than is the case with nitrogen."
