This has been a thing since 3D graphics, it's also why fov adjustments have been common place since at least Quake.
btw you can adjust the fov more in Doom using console commands. The command is "g_fov". Now the difference here is going to be even more exaggerated on my 32:9 display, but here's a quick screen shot of the difference between a FOV of 100 and FOV of 75 in Doom 2016. Note, that a fov of around 75 is really common on consoles to try and reduce that fisheye effect.
Thanks Trunks, I'll play around with it a bit. I don't wear glasses, but I think I understand what you're saying.
