Wil Gomez with some wild speculation that absolutely makes common sense. There is precedent for Apple Glasses.
Glasses, just like a watch, are both stylish and utilitarian which is why Apple Watch has become such a success. It looks great– thanks to a growing variety of easily interchangeable bands– and is completely utilitarian in that it becomes an external extension to iPhone capability, just as both iPhone and iPad have taken functionality away from the confines of a Mac or Windows PC and made them more portable and mobile.
How will they differ?
They will differ from Google Glass in the ways that Apple makes everything different than what competitors do. First, it will be an extension of the iPhone (initially you’ll need an iPhone to make it work, but in the future Apple Glasses, just as Watch will be, will be fully standalone). Second, Glasses will be available in a variety of glass frames and styles, both in clear lenses and eventually prescription lenses (likely in concert with a major optometry chain). So, in many respects, Apple Watch is a precursor to another Apple wearable with entirely different functionality.
What will they do?
Augmented reality; application images which appear on the screen in the lenses that match up with what you see through the lenses, all within your field of vision. Apple Glasses will do what Google Glass did not.
They need to have a lower price tag.
