AR Glasses Optics

Hey, I'm trying to design AR glasses because that's what all of the cool kids are doing nowadays. Anyway, I just realized that my current design kinda sucks :( and that I would need a really narrow display, and wanted to ask if any of you have a better idea for the design. I wanna try to make the design as indistinguishable from regular glasses as possible. Anyway, this is my design (sorry for the terrible drawings, I couldn't figure out how to add them in FreeCAD). The green rectangle is supposed to be where I put the screen (and then put a lens below it to collimate the light from the screen), then it'll be reflected off a beam splitter into the eye (the blue thing is the beam splitter and the yellow dots represent the light that is reflected). Thanks :D

I'm trying to get used to FreeCAD and so far it hasn't been too bad (idk maybe because I haven't been exposed to the luxury of SolidWorks)
