Pros
Pro Augmented Reality possibilities
Because these glasses have their displays right in the middle of your vision, they can project digital images ontop of reality (augmented reality - AR for short). This means you can get contextual data about an item right in your field of view. This tech can be used by interior designers to see how a room would look like with different furnishings in different places, as well as more everyday uses like drawing a navigation line ontop of the road when navigating.
Pro You can run any Android apps on the device
While there is no access to the PlayStore, you can sideload apps onto it. The primary interface for Android apps will be the wired controller.
Pro Reflective display
Instead of shining light directly into your eyes, the light simply reflects off the glass, meaning its less obtrusive.
Pro Adaptable technology
The technology used in the Carl Zeiss Smart Glasses project can be transferred to normal glasses, or wherever curved glass is present. This solves the fundamental issue with Google Glass, which required an out-of-place flat piece of glass to function.
Pro Low-profile
The glasses look very much like regular, non-smart glasses.
Cons
Con Unadjustable
These glasses don't have any ability to be adjusted - this isn't tech you'll be easily be able to share with others while remaining comfortable. It also means that if you normally wear glasses, you will need to wear those under these smart glasses.
Con Clunky controls
Most of the controlling will be done through the wired touchpad. This is a clunky implementation, and requires a wired attachment. It isn't ideal for out-and-about usage, which is what smart glasses excel at.
Con Not meant for consumers
While they could be used for consumers, they haven't been designed for average consumers. These are meant for businesses - possibly museums, engineering firms, or designers. There may not be much non-enterprise software available for the average user.
Con Hardware only (for now)
Carl Zeiss is a company that makes optics, and doesn't work on software. This is only a hardware solution, with no software implementation yet. Currently Carl Zeiss is seeking a software partner, however this will take time for them to develop a complete product once they do find a suitable partner.
Con Not yet available
These glasses are currently in prototype stage. It's not clear when and even if they will go into production.
