I have used Vogmasks for 3 years (and used other masks for years before that), and I wear them when visiting WDW and cruising
DCL. When outside I am also usually wearing Solar Shields sunglasses over my normal glasses and sun protective clothing including a hat. so if I am outside you can't see most of my face, including my eyes. My current Vogmasks are the N99 with dual exhale ports, but I also have the original style with no exhale ports (it gets a lot hotter and in warm humid Florida with get damp almost wet, so I have found the dual port ones are more comfortable in such an environment).
I have NEVER encountered a problem from Disney employees, including security. At the WDW bag check line, when I get up to the security officer if it is decently shaded and I do not have a migraine I will pull my sunglasses to the top of my head so they can at least see my eyes. I smile and hand them my bag-ready-to-be-searched. Other times it is too sunny and/or I have a migraine and the sunglasses stay on. They have never asked or said anything about the mask.
I have had kids near me at WDW or on the cruise ask their parents some variation of "why is she wearing that" ? Most parents reply "to keep her from getting sick" or "for allergies", which happen to be the reasons I do

A couple of times the parent has prompted the kid to ask me, and a few times a particularly bold child just came up to me directly and asked. I always answer "for allergies and to keep me from getting sick". that has always been a satisfactory answer and the kid will thank me or not and walk away.
Unlike when I wear the mask at home when taking public transit, adults don't as noticeably try to avoid me at WDW. At home on public transit about half the people who were aiming to sit beside me choose not to when they realize/clue in I am wearing the mask. At WDW perhaps pepople don't pass me quite as close as they may others, and leave be a bit extra room in lines, but for the most part it is negligible.
I have had ONE incident at WDW where an idiot adult walking towards me clearly saw the mask, then proceeded to literally jump right in front of me and make a noise (I do not even know how to describe it) right in my face. I rapidly shifted away from him and he just kept on walking. I have no clue what he was trying to do other than be an absolute idiot.
I have asked for a
DAS while wearing the mask.
When interacting with CMs indoors where I am requesting something (e.g. guest services; hotel desk), if there aren't many other people around I will pull the mask down briefly and smile as I start the conversation and then put the mask back up and continue the conversation. it seems to put people a bit at ease and I don't mind doing it under certain circumstances.
I have also worn my Vogmask or a 3M N99/N100 mask in airports, on airplanes, on trains, and on public transit. I've worn it to baseball games in a MLB park and many other public venues. When indoors I try to put the sunglasses on the top of my head so at least people can see my eyes. At airports people usually will not sit right beside me, which I am fine with. On our last trip, the family with the two little girls who were hacking and coughing DID decide to sit beside and across from me, though. I relocated myself as I did not want to be covered in whatever germs they were spreading, let alone catch it.
My advice: if you know or feel you need to wear the mask, WEAR IT. Ignore the idiots (their problem) and don't worry about the side glances and occasional mutterings or kids asking questions (well, if they ask you directly, answer them

). If people don't want to sit or stand beside you, or if they give you a wider berth or a buffer zone when standing in line, be glad for the extra space and that there are people who are that considerate (even if it is really because they think you have the plague) !
Decide in advance if there are situations where you will be ok with briefly or for a longer time taking the mask off or pulling it down, and then decide at the time if you still wish to.
Have an answer in your head for if people ask why you are wearing the mask ("so I don't get sick" works very well, IME).
FWIW, I first started wearing my mask regularly when my job required me to commute about 90 minutes each way on city buses. The first few months I did not wear a mask and I was constantly sick. Once I started wearing the mask for the commute, I rarely got sick.
Finally, sometimes the mask gets annoying and you need to adjust it. Bring hand sanitizer or sanitizing wipes and try to train yourself to use them on your hands BEFORE you go messing with the mask. You won't always catch yourself, but with time you will more often.
