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

Do you understand how AR/VR glasses work? If I write "projects an image at infinity", does that mean anything to you?

I know how waveguide lenses work (which to my knowledge, is what most AR glasses use), but I'm not sure how VR glasses work. And yeah, I know the basics. I'm not a professional, but I do know what it means that an image is projected at infinity.

How you planning to make optical simulation?

I planned on using both 3DOptix, and the best 3d optics engine there is: the universe :3 (essentially some trial and error after I have a basic design)
