Hey! and Welcome!
Most display setups will always have some difficulty with humidity.
However with the Vision's, I beleive the area for the lighting is option. As in you can fill it in with a peice that's provided. At least it used to be the case.
However there's many ways to help regulate Humidity if your concerned. Alot of people using Tanks or Terrariums put aluminum foil over 3/4's of the screens or vents, or even regular silver duck tape (outside only).
Also your choice of substrate will change things up too. For humidity issues it's hard to go past Coconut Fiber based substrates, like eco earth, for maintaining and holding humidity.
The choice is really yours, but be prepared to do a little tinkering regardless of what you choose. I always say that's half the fun!
Here's mine, and how I deal with my screen on top.
