I believe that "Vision Pro", the name of Apple's new product is it's complete name, rather than the "Pro" version of a "Vision" product line.
Humans are already equipped with natural vision through our eyes and optic nerves. "Vision Pro" is a tool to apply and amplify that natural vision to accomplish professional and recreational tasks.
Therefore, future potential products in this line could be named Vision Pro Max (never Vision Max), or Vision Pro Air (never Vision Air), or Vision Pro SE (never Vision SE).
Additionally, the name "Vision Pro" is more distinctive and more easily trademarked than the single common word "vision".
