Take note that visual triggers don't necessarily mean that it triggers when the thing sees you or you see it. If the trap actually says "Trigger sight", then it means it actually triggers by looking at it, which means you have to look at and interact with it indirectly (e.g. through a mirror, hence why every rogue's kit has one) to avoid triggering it. When it says "Trigger visual" that means that within some area (usually shown on a map), if you are visible, then you will trigger the trap. You might be able to bypass this by something like invisibility, but the spell can also be made with Truesight or something similar to override that.
