I get it, it’s the 32nd century and the glasses are maybe heads up displays that only he can see and use. But don’t you think in three thousand years they would have figured out how to build that stuff INTO or ONTO the eye? Instead of making the person, or the person choosing to wear an ancient form of corrective lenses.

We’ve had buttons for a long time, some people are just hipsters.
But also, Star Trek has a long history of justifying contemporary-looking people as a fashion choice.

And also makes casting and wardrobe choices a lot simpler, but I don’t think the book said that.
