Since Google introduced its smart glasses in 2013, with very little success among consumers, there have been some attempts made by various companies to try to extend their consumption.
So far with very little success and limited to very specific applications.
Pero como se trata de buscar una alternativa al móvil, lo siguen intentándolo y uno de los últimos ha sido Facebook y sus Ray-Ban Stories, que parece ser que también van a tener unas ventas limitadas.
Replacing the mobile phone is not going to be easy at all, and there are those who say that we will have a "device" for many years in the future. It has become so versatile, so powerful and easy to handle that it is hardly replaceable, no matter how much metaverse Mr. Zuckerberg looks for.

The new Ray Ban smart glasses need to connect to a mobile to talk, and they hardly take photos and nothing else. They are a mobile accessory with the disadvantage for our privacy that it is not easy to know when they are recording us with them.
I have seen information from some Xiaomi glasses that do present information on the lenses so that they can be used with Augmented Reality APPs, but they are still in the prototype phase.

In conclusion, smart glasses will soon be 10 years old and are still only used in very specific market niches.
Mobile is still "the king" of communications and human applications, and at the moment no one is expected to overshadow it in the near future.
But of course, nobody knows the future.
